- VPE valve-pump unit
- This valve-pump unit VPE provides two selective switching positions of a multi-way valve MWV in the form of a 4/2-way valve between the first circuit and the second circuit.
- FIG. 2 illustrates which components of the first and second circuit are integrated into this valve-pump unit VPE by means of a common housing section Gg.
- the housing section Gg thus has a centrally supporting and integrating function.
- a single electric motor or electric motor EM designed as an internal rotor and dry-runner, is joined to the multi-way valve MWV in such a way that the multi-way valve MWV encloses the electric motor EM in a ring—roughly completely or in a closed manner—within the common housing section Gg.
- the electric motor EM forms a central or central driving component of the valve-pump unit VPE.
- the stator S of the electric motor EM is arranged within a pipe section RA or at least a pipe-like section RA, with this pipe section RA being adequately sealed at both ends in an assigned area relative to its periphery and thus providing a drying space for the stator S and forms the rotor R of the electric motor EM within the pipe section RA.
- the multi-way valve MWV joined to the pipe section RA has at least one section 2 that is stationary with respect to the housing section Gg and at least one section 4 that can be pivoted with respect to the housing section Gg in a first or a second direction of rotation of the electric motor EM.
- Heat transport medium channels 6 (or liquid channels 6) in the multi-way valve MWV extend between the housing section Gg and the electric motor EM.
- the individual sections 2, 4 of the multi-way valve MWV can be cut out in sections on the outer circumference to save weight and, in connection with the common housing section Gg, form individual cavities in which pumped fluid or pumped liquid can collect (FIG. 2).
- the valve-pump unit VPE has a first pump stage PSi, for example in the form of a flow pump stage, e.g. in the form of a radial pump stage, and a second pump stage PS2, for example in the form of a flow pump stage, e.g. in the form of a radial pump stage, each of which has a Drive shaft 8 of the electric motor EM can be driven.

- the two pump stages PSi, PS2 each have at least one first and second housing section Gia, G or G2a, G2b.
- a three-stage reduction gear RG for selectively adjusting the multi-way valve MWV is provided or arranged between the pump stage PSi and the electric motor EM.
- the sectional view in Fig. 4 (corresponding to a section through the section line or plane Si - S1 in Fig. 2) illustrates the gears Z1, Z2, Z3 of the first and second gear stages and the sectional view in Fig. 2 (corresponding to a section through the section line or plane S2 - S2 in Fig. 2) the gear Z4 of the fourth gear stage.
- the gear Z4 meshes with an internal toothing 24 formed on the pivotable section 4 of the multi-way valve MWV, so that the section 4 functions in the sense of a ring gear which can be selectively pivoted via the gear Z4.
- the section 4 pivots in a direction of rotation of the electric motor EM, which corresponds to the pump operation of the electric motor EM.
- the section 4 can also pivot in a direction of rotation of the electric motor EM that is opposite to the pump operation.
- a freewheel FL - for example in the form of a clamping roller freewheel - is provided or arranged between the drive shaft 8 and the gear wheel Zi, which only transmits a torque to the reduction gear RG in a direction of rotation opposite to the pump operation of the electric motor EM and thus the selective adjustment of the multi-way valve MWV allows in at least two switching positions (Fig. 4, Fig. 2).
- the freewheel FL could also be arranged at a different point on the reduction gear RG.
- the drive shaft 8 extends through a roller bearing arrangement - in the form of a floating bearing - to accommodate the drive shaft 8 in the housing section Gg, the freewheel FL, a seal 12, a plain bearing 16 and into a metal bushing 20, e.g. Brass bushing on which the impeller of the PSi pump stage sits.
- a roller bearing arrangement - in the form of a floating bearing - to accommodate the drive shaft 8 in the housing section Gg, the freewheel FL, a seal 12, a plain bearing 16 and into a metal bushing 20, e.g. Brass bushing on which the impeller of the PSi pump stage sits.
- the drive shaft 8 extends into a hub section N of a centrifugal clutch K, via which the pump stage PS2 is connected to the electric motor EM.
- a drive shaft 10 extends from this centrifugal clutch K through a seal 14, a sliding bearing 18 and into a metal bushing 22, for example a brass bushing, on which the impeller of the pump stage PS2 is seated.
- the centrifugal clutch K is designed in the sense of an opening clutch, which opens at a certain speed of the drive shaft 8 and thereby releases the operative connection of the electric motor EM to the pump stage PS2.
- the pump stage PS2 can be uncoupled or ejected by the centrifugal clutch K in pump operation if required in a corresponding operating mode of the electric motor EM.
- the centrifugal clutch K is arranged within the pipe section RA between the electric motor EM and the pump stage PS2.
- the two seals 12, 14 help to keep the reduction gear RG, the centrifugal clutch K and the electric motor EM dry.
- the sectional views in Figs. 5, 6 illustrate the said centrifugal clutch K, which has a closed rotating disc section 34 formed on the hub section N and a closed rotating disc section 34 formed on the disc section 34 Ring section 32 includes.
- arcuate claws 30 for receiving a closed to running spring element 28 is formed.
- claws 30 are spaced radially from the ring section 32 with respect to their extent in the circumferential direction of the centrifugal clutch K in such a way that they form an arcuate gap with the ring section 32 into which an associated spring element 28 is inserted.
- each of these spring elements 28 carries a so-called dome lining element 26, which is formed in a manner corresponding or complementary to the section of the drive shaft 10 shown in FIG.
- This dome lining element 26 can be an element consisting of suitable friction means and binding agents or an element comprising such friction means and binding agents.
- the dome covering element 26 can also be formed from an elastomer or can include such an elastomer.
- the coupling lining element 26 forms a positive and non-positive connection with the said output shaft section (FIG. 5).
- the clutch in the form of a closing centrifugal clutch.
- the electric motor EM of the valve-pump unit VPE can be operated in two directions of rotation: a) in said pump operation in a first direction of rotation; and b) for driving the reduction gear RG in a second direction of rotation, opposite to the pump operation, for adjusting the multi-way valve MWV.
- the reduction gear RG is decoupled from the electric motor EM via the freewheel FL.
- the adjustment of the pivotable or rotatable adjustable multi-way valve MWV can be carried out stepwise or stepped or continuously from one switching position to another switching position of the multi-way valve MWV.
- FIG. 2 One of two switching positions of the 4/2 multi-way valve MWV can also be seen in Fig. 2, in which an outflow or outflow connection Aps2 of the pump stage PS2 or of the second circuit is in fluid connection or flow connection is established.
- Fig. 2 illustrates a series connection of the two aforementioned circuits - i.e. the first and second heat transport medium circuit - in which the outlet Aps2 is fluidically connected to an inlet Zpsi - not shown in Fig. 2 - of the pump stage PSi or the first circuit.
- the same also applies to an outflow or outflow connection Apsi—not shown in FIG. 2—of the pump stage PSi or the first circuit, which is fluidically connected to an inlet Zps2—not shown in FIG. 2—of the pump stage PS2 or the second circuit connected is.
- the outlet Apsi is fluidly connected to the inlet Zpsi and on the other hand the outlet Aps2 is fluidically connected to the inlet Zps2, specifically via an assigned channel 6 in the multi-way valve MWV.
- the delivered fluid or delivered liquid is diverted accordingly in the multi-way valve MWV.
- the multi-way valve MWV can have an arrangement of correspondingly designed channels 6--not shown here--which bring about or bring about such mixed states within the multi-way valve MWV.
- more freewheels can also be provided, namely on the pump stage PSi between the metal bushing 20 and the drive shaft 8 and / or on the pump stage PS2 between the metal bushing 22 and the drive shaft 10.
- This has the Advantage that pumped fluid is not slowed down in the direction of rotation of the electric motor EM, which is opposite to the pump operation, but rather can advantageously continue to flow due to its mass inertia.
- the proposed valve-pump unit makes it possible to greatly simplify the previously mentioned heat-transport medium circuits or a heat-transport medium system having such heat-transport medium circuits.
