`
`Description
`
`[0001] The invention relates to a feed
`pump as well as to an adjustable feed-,
`flow control- and shutoff element for
`fluids, in particular to an electrically
`operated element that can be used as
`feed pump, restrictor, and/or shutoff
`element.
`[0002] Feed pumps for fluids are known
`in many embodiments. In order
`to
`convey liquids, typically displacer units
`are used, and
`for gases usually
`continuous-flow machines. However,
`continuous-flow machines are equally
`suited as feed pumps for liquids. If
`especially simple and economically
`designed feed pumps are to be used
`where efficiency is not a high priority,
`simply
`designed
`continuous-flow
`machines with rotating vane blades or
`the like are especially suitable. For many
`applications, reversing the direction of
`flow makes sense, which, however, can
`be realized with
`the
`typically used
`electric drives only with an expensive
`control. If additional tasks are to be
`completed,
`such as,
`for example,
`restriction of flow-through or a shutoff
`function, a circuit with additional
`components cannot be avoided.
`[0003] A problem on which
`the
`invention is based is seen in particular in
`providing a variable and universal feed
`element which, if applicable, can restrict
`or prevent a flow-through.
`[0004] According to the invention, this
`problem is solved by the teaching of the
`independent claims, wherein features
`listed
`in
`the respective
`independent
`claims further develop the solution in an
`advantageous and useful manner.
`[0005] A feed pump according to the
`invention
`for
`fluids,
`having
`the
`characteristics of Claim 1, has a very
`simple design and can be produced
`
`
`
`2
`
`in
`large quantities
`in
`economically
`series- and mass production. The feed
`drive comprises an electrically operated
`rotor with a series of permanent
`magnets, which
`is a
`rotor of a
`synchronous machine. By arranging the
`rotor between a series of coil pairs, a
`random direction of rotation can be
`selected with
`suitable
`electronic
`actuation. In this way, the feed pump is
`provided for a feed in various directions.
`The feed rate can be selected in a simple
`manner by controlling the speed of the
`rotor.
`[0006] The coils arranged at both sides
`of the disk-shaped rotor allow a precise
`actuation of the feed rotor and the
`control of its speed. Advantageously, the
`coils can also be developed as flat coils
`that are placed on a circuit carrier and in
`this way are easy and economical to
`produce.
`[0007] The housing halves of
`the
`housing preferably have a respective
`funnel shape, which widens from a line
`connection respectively in the direction
`of a connecting plane so that the housing
`halves each have a connecting flange for
`a detachable and sealing connection. The
`disk-shaped rotor is preferably disposed
`approximately at the same height as said
`connecting section developed as flange
`because
`this point has
`the
`largest
`diameter. So as
`to be able
`to
`accommodate the rotor, the connecting
`section has a flat cylindrical contour of
`low height. On the outside, the two
`housing flanges can be screwed together,
`for
`example,
`or
`detachably
`or
`permanently
`connected
`in
`another
`manner. For example, gluing or welding
`is also an option.
`[0008] The rotor as well as the housing
`can be advantageously made of synthetic
`material,
`in particular of
`injection-
`molded
`synthetic material, with a
`
`Petitioners' Exhibit 1011, pg. 3

`

`DE 103 07 696 A 1
`
`to

`respective
` The permanent
`improve
`firmness.
`magnets of the rotor can be preferably
`encapsulated by the synthetic material so
`as to avoid coming into contact with the
`feed medium because of a thin coating
`with synthetic material. If the coils are
`embedded in the synthetic material of
`the housing in the same way, the feed
`pump can also convey aggressive and
`corrosive fluids and media without
`having to fear damage or wear and tear.
`So as to even further improve the
`resistance
`to media
`influences,
`the
`surfaces may be provided with an
`additional coating that seals all pores and
`can offer protection against corrosion
`and abrasion.
`[0009] A feed-, flow control and shutoff
`element according to the invention for
`fluids having the characteristics of the
`independent Claim 23 comprises a rotor
`that is rotatable in a housing and [a] has
`vane-
`and
`shutoff
`section
`that
`corresponds with the appropriate shutoff
`segments
`of
`the
`housing. With
`appropriate actuation of the rotor, the
`element according to the invention can
`function as flow control element or as
`shutoff
`element.
`The
`remaining
`activation of the rotatable rotor with the
`drive coils corresponds to the feed pump
`already described above. In addition, the
`functions of the precise positioning of
`the rotor in certain angle positions can
`be realized with suitable positioning
`coils. Said positioning
`coils
`also
`cooperate with the permanent magnets
`of the rotor and can place the rotor in
`certain angle positions in which through-
`flow is restricted or completely stopped.
`[0010] The number of the positioning
`coils and the drive coils as well as the
`number of
`the permanent magnets
`determines the feasible feed volume as
`
`
`
`3
`
`well as the realizable efficiency of the
`pump.
`[0011] The feed pump according to the
`invention is suitable, for example, as a
`recirculation pump for liquids in a great
`number of applications. For example, it
`can be used as a recirculation pump for
`coolant
`in
`stationary
`or mobile
`operation. The feed-, flow control- and
`shutoff
`element
`according
`to
`the
`invention can be used in particular as
`feed pump for a heating system or, for
`example, for a communal heating/ power
`station. Here, the return sense of rotation
`is in particular of advantage because in
`this way, a cold motor can be flushed
`with heated water from a water reservoir
`prior to start. To that end, the water can
`be removed in an upper area of the
`reservoir. Then the sense of rotation
`can be reversed and the water that was
`heated by the heat of the motor can be
`fed back into the reservoir.
`[0012] Other
`also
`are
`applications
`feasible and useful, such as, for example,
`a use in the chemical industry where
`frequently aggressive media have to be
`pumped. This is where wear and tear and
`an unexpected pump failure can lead to
`problems. The feed pump according to
`the invention and/or the feed-, flow
`control- and shutoff element according
`to the invention can provide a remedy
`for these problems.
`[0013] Further
`and
`characteristics
`advantages of the present invention are
`described in the dependent claims as
`well as the descriptions of the figures
`below.
`[0014] The invention is explained in
`greater
`detail
`below,
`using
`the
`description of preferred exemplary
`embodiments and with reference to the
`attached drawings, which show:

`the
`component
`according to FIG. 1,
`[0018] FIGS. 4 and 5 a schematic
`representation of a rotor in top view and
`in section;
`[0019] FIGS. 6 and 7 a top view of
`respective schematic representations of
`housing halves of
`the component
`according to the invention, and
`[0020] FIGS. 8 and 9
`schematic
`representations of the drive-generating
`components of the component according
`to the invention.
`[0021] Using the following FIGS. 1 to
`9, a component according
`to
`the
`invention is explained, which, depending
`on the design of a rotor that will be
`explained farther below, as well as one
`of two housing halves joined together,
`can be a feed pump 2 or a controllable
`feed-, flow control- and shutoff element
`4. To simplify matters, reference will be
`made in this context either to a feed
`pump 2 or a pump 2 or an element 4.
`The component described as element 4
`has
`the aforementioned controllable
`functions of feed, flow control and/or
`shutoff. Identical parts principally have
`the same reference numbers
`in
`the
`FIGS. 1 to 9 and therefore do not
`require multiple explanations.
`[0022] The element 4 comprises a
`housing 6, which consists of a first
`housing half 18 (respectively at the top
`in FIGS. 1 to 3) and a second housing
`half 20 (respectively at the bottom in
`FIGS. 1 to 3). In the assembled state,
` housing halves 18, 20 are
`both
`detachably or non-detachably connected
`to one another in a center connecting
`
`
`
`4
`
`section 26. The connecting section 26 is
`designed as a flange that simultaneously
`has a guide-, positioning- and sealing
`function.
`In
`the shown exemplary
`embodiment, the second (lower) housing
`half 20 has a circumferential centering
`web 38 which encloses the flange of the
`first housing half 18 in a sealing and
`positive-locking manner (see FIGS. 2
`and 3).
`[0023] Both housing halves 18, 20 have
`a funnel-shaped design and taper in
`opposite directions to a respective line
`connection 24. As needed, said line
`connection can have a design such as,
`for example, also as a connecting flange
`or as a hose connection or the like. The
`two housing halves 18, 20 can be either
`screwed
`together, which creates a
`detachable connection; however, other
`types of detachable connections are
`feasible as well, for example with
`clamps, clips, locking hooks or the like.
`If the housing halves 18, 20 are not to be
`separated again after assembly, they can
`also be glued, welded or
`riveted
`together. In that case, in case of a defect,
`only
`the entire component can be
`exchanged rather than individual parts.
`[0024] A
`rotor 8
`that
`is
`rotatably
`disposed on a plane approximately at the
`height of the connecting element 26 will
`be explained in detail later using FIGS.
`4 and 5. The rotor 8 has a flat cylindrical
`contour, with a hub 30, a peripheral ring
`32, and vane blade sections 34 and
`shutoff- or disk sections 36 arranged in-
`between. With its hub 30, the rotor 8 is
`rotatably run on a bearing on a shaft 28
`of the second housing half 20. Said
`bearing optionally can be a friction
`bearing or a roller bearing. As soon as
`the rotor 8 rotates, it is centered by its
`drive elements as well as by the flow
`forces of the pumped fluid engaging at
`said rotor so that in the ideal case, said
`
`Petitioners' Exhibit 1011, pg. 5
`
`

`

`DE 103 07 696 A 1
`
`rotor loses the engaging contact with the
`shaft 28 and simultaneously has a
`cantilever bearing or a flow bearing.
`[0025] A generally known direct current
`synchronous machine is used as drive for
`the rotor 8. For this purpose, the rotor 8
`has in its peripheral ring 32 a series of
`evenly spaced permanent magnets 12,
`which can be firmly anchored in the
`peripheral ring 32 as small, cylindrical
`units, for example. In the connecting
`section 26, drive coils 10 are arranged
`8,
`above
`and
`below
`the
`rotor
`respectively, on the same periphery as its
`permanent magnets 12, said drive coils
`being able to ensure a rotation of the
`rotor 8 with appropriate activation. For
`example, the drive coils 10 can be
`applied as printed circuit boards on a
`ring-shaped circuit carrier 16. Arranged
`8,
`above
`and
`below
`the
`rotor
`respectively, is a circuit carrier ring 16
`provided with drive coils 16. The drive
`coils 10 are preferably always arranged
`in opposite pairs so that they can ensure
`a magnetic
`field
`in
`a direction
`perpendicular
`to
`the direction of
`movement of the rotating permanent
`magnets 12.
`[0026] The drive principle of
`the
`synchronous motor is shown by way of
`the schematic representations in FIGS. 8
`and 9.
`In
`the
`shown exemplary
`embodiment, a permanent magnet 12 of
`the rotor 8 is to execute a movement
`from left to right, which corresponding
`to the perspective view, corresponds to a
`counter-clockwise rotation. The polarity
`of the respective opposite pairs of drive
`coils 10
`is selected such
`that
`the
`permanent magnet 12 is pulled into the
`direction of the coil pair 10. Shortly
`before the magnet 12 passes the coil pair
`10, the voltage is turned off so that the
`magnet coasts by unpowered. Shortly
`after the magnet 12 has passed the coil
`
`
`
`5
`
`pair 10, the polarity of the voltage is
`the magnet 10
`reversed
`so
`that
`[Translator’s note: sic, 12?] is repelled
`by the coils 10. The speed of the rotor 8
`can be controlled with corresponding
`activation of the coils.
`[0027] To place the rotor 8 in smooth
`and non-jerking
`rotation,
`the drive
`preferably works with “handshake.” This
`means turning off the electrical field
`shortly before the magnet passes. Such a
`torque gap can usefully be about 4o and
`is
`overall
`compensated
`by
`the
`multiplicity of magnets and coil pairs.
`[0028] A current flows through the coils
`when a voltage is applied to the coils.
`Said
`current
`causes
`a
`respective
`magnetic field in the coil, which also
`builds up in the air gap. The impeller
`with the permanent magnets is located in
`said
`air
`gap. Because
`of
`the
`aforementioned field, the magnets are
`attracted. If they are approx. 2o before
`the complete overlapping, the current is
`turned off until the magnet is positioned
`2o after the complete overlapping. Then
`the coil is loaded with an opposite phase
`position and voltage so that the magnetic
`field
`then
`reverses and
`repels
`the
`magnet.
`[0029] The speed can be controlled in a
`simple manner with
`the electronic
`the drive coils 10.
`activation of
`Likewise, the direction of rotation of the
`rotor 8 and thus the feed direction of the
`pump 2 and/or the element 4 can be
`reversed in a simple manner.
`[0030] The rotor 8 has the vane blade
`sections 34 required for conveying fluid,
`which
`in
`the
`shown
`exemplary
`embodiment are respectively separated
`from the shutoff sections 36. If the
`component according to the invention is
`to be operated only as a feed pump 2, it
`is possible to provide only vane sections
`34.
`In
`the
`shown
`exemplary
`
`Petitioners' Exhibit 1011, pg. 6
`
`

`

`DE 103 07 696 A 1
`
`vane
`respective
`five
`embodiment,
`sections 34 and five shutoff sections 36
`are provided (see FIGS. 4 and 5). In the
`respective same position as the vane
`sections 34, permanent magnets 12 are
`arranged in the peripheral ring 32, thus
`five
`in
`the
`shown
`exemplary
`embodiment. However,
`significantly
`more magnets 12 may be provided,
`which can correspondingly increase the
`feed performance of the drive. The more
`magnets and coils there are, the higher
`the
`achievable
`feed
`performance.
`However, the number of coils is limited
`by the space available in the circuit
`carrier ring 16. If the feed performance
`is to be increased nevertheless, it may be
`necessary to enlarge the outer diameter
`of the connecting section 26 and thus the
`circuit carrier ring 26 as well as the rotor
`8.
`[0031] The vane sections 34 consist of
`obliquely positioned blades
`that are
`arranged between the hub 30 and the
`peripheral ring 32 of the rotor 8. The
`oblique positioning of the blades is
`preferably dimensioned such that the
`rotor 8 does not exceed a desired length.
`The edges of the vane blades 34, which
`point downward in the shown illustration
`(FIG. 4), respectively border an edge of
`an adjacent shutoff section 36, which
`preferably has the same width as the
`vane blades 34, but no tilt. This means
`that they are designed as flat disk
`segments which during a rotation of the
`rotor 8 alternately brush over the shutoff
`segments 40 and the funnel segments 44
`of the second housing half 20 at a small
`distance.
`[0032] Their design is illustrated in the
`top view in FIG. 6. An equal number of
`funnel segments 44, of shutoff segments
`40 as well as of shutoff sections 36 at the
`rotor 8
`facilitates a
`flow-through
`restriction or a shutoff of the element 4,
`
`
`
`6
`
`depending on the control of said rotor.
`For
`this purpose,
`a number of
`positioning coils 14 are provided
`adjacent to the drive coils 10, which in
`cooperation with the permanent magnets
`12 facilitate a specific rotation angle
`positioning of the rotor 8. Because the
`rotor 8 has five permanent magnets 12
`in the shown exemplary embodiment,
`but only four respective positioning coils
`14 are provided in the connecting section
`26, the rotor 8 can be brought into nearly
`any desired position. In
`this fixed
`positioning, the drive coils 10 are turned
`off.
`[0033] For
`suitable
`example, with
`activation of the positioning coils 14, the
`rotor 8 can be brought into a position in
`which a respective shutoff section 36 is
`arranged congruently above a shutoff
`segment 40 of the second housing half
`20. In that case, the flow can pass the
`rotor 8 without hindrance. No feed takes
`place. However, if the shutoff sections
`36 of the rotor 8 are brought into a
`congruent position above the funnel
`segments 44, the element 4 is locked; no
`fluid can flow
`through. In-between,
`random
`intermediate positions
`are
`the element 4
`possible,
`in which
`functions as a variable restrictor. With
`inactivated positioning coils 14 and
`suitable activation of the drive coils 10,
`the element 4 can convey
`in any
`direction and at a variable feed rate.
`[0034] The positioning coils 14 located
`in the second housing half 20 can be
`preferably activated such that the rotor 8
`is pulled onto the face of the second
`housing half 20 and rests there firmly.
`With sufficiently precise production, an
`approximate sealing of the closed rotor 8
`can be achieved, which can withstand a
`certain fluid pressure.
`[0035] As illustrated by the longitudinal
`section in FIG. 2 as well as the top view
`
`Petitioners' Exhibit 1011, pg. 7
`
`

`

`DE 103 07 696 A 1
`
`in FIG. 6, the radially inward pointing
`shutoff segments 40 do not border each
`other in the center, but rather leave a
`center cross-section that corresponds to
`the
`inner cross-section of
`the
`line
`connection 24 open. At the contact
`surface of the rotor, the upper areas of
`the shutoff segments 40 are each
`connected by the ring section 42, in the
`center of which the shaft 28, which
`projects perpendicularly upward and
`situates the rotor 8, is arranged. The
`funnel segments 44, which regularly
`alternate with the shutoff segments 40,
`have approximately the same contour as
`the corresponding funnel section 22 of
`the first (upper) housing half 18.
`[0036] Their design
`smooth
`and
`transition into the upper line connection
`24 is illustrated in the schematic top
`view in FIG. 7.
`[0037] Furthermore, the FIGS. 6 and 7
`show the arrangement of the ring-shaped
`circuit carrier 16 with the drive coils 10
`and the positioning coils 14 arranged
`thereon.
`[0038] The rotor 8 can advantageously
`be made of injection-molded synthetic
`material, which may have a stiffening
`fiber
`reinforcement,
`for
`example.
`12
`Preferably,
`the magnets
`are
`encapsulated so that they do not come
`into contact with the feed medium. For
`example, the permanent magnets 12 can
`be inserted into the injection mold and
`then encapsulated with the synthetic
`material in one shot. In this way, large
`quantities of the rotor 8 can be produced
`very economically in the desired design.
`[0039] In the same way, the two housing
`halves 18, 20 can be made of injection-
`molded synthetic material. Here too, the
`synthetic material used for this purpose
`can have a fiber reinforcement. It may
`also be of advantage here as well if the
`coils 10, 14 are encapsulated so as not to
`
`
`
`7
`
`come into contact with the feed medium.
`The circuit carrier rings 16 can be placed
`into an injection mold and encapsulated
`in the same way. The terminal contacts
`for activating the coils 10, 14 can be led
`out of said form and in doing so, be
`hermetically encapsulated.
`[0040] A useful funnel angle of the two
`housing halves 18, 20 may be, for
`example, at an angle of approx. 20 to 60o
`relative
`to
`the
`longitudinal
`axis.
`Preferably, the angle is approx. 35 to 45o
`to achieve relatively favorable flow
`conditions.
`[0041] Glass fiber or carbon fiber is
`especially
`suitable
`as
`fiber
`reinforcement. A
`suitable
`synthetic
`material
`is basically any
`injection-
`moldable thermoplastic. If applicable,
`the components can also be produced
`from thermosetting synthetic material in
`a molding process. The use of synthetic
`material has in particular advantages
`with respect to media resistance of the
`surfaces as well as with respect to the
`production costs of large quantities.
`[0042] The feed pump according to the
`invention is suitable as an economic
`mass
`product,
`for
`example
`as
`recirculation pump of a coolant system
`of a motor vehicle or the like. It is
`excellently suitable as a recirculation
`pump of a heating plant or also as a feed
`pump for the chemical industry.
