Description

DISTRIBUTOR BODY OF A FLUID VALVE Technical field of the invention

The invention relates to a distributor member of a valve for fluid, in particular a heat transfer fluid, an associated valve and fluid circuit. This distributor member and/or this valve and/or this fluid circuit will find their applications, for example, in the field of motor vehicles.

Technical background

Fluid circuits are known that allow thermal conditioning of different parts or areas of a motor vehicle, in particular its batteries and/or its passenger compartment. With the proliferation of hybrid or electric engines, these circuits have many branches in order to be able to meet the thermal management needs of the vehicle in various operating modes.

To circulate the fluid in their different branches, such circuits include a large number of valves connecting the branches together according to different configurations depending on the desired operating mode. Such a number of valves increases the pressure losses. They also make the control of the circulation of the fluid more complex and increase the cost of these circuits.

Rotary valves have also been proposed that allow multiple inputs/outputs to be connected in order to provide more possibilities for fluid circulation between the branches of the circuits compared to standard two-, three- or four-way valves. However, these valves have a large footprint that limits their use.

The present invention aims to at least partially overcome the drawbacks stated above and to this end proposes a distributor member of a fluid valve, said distributor member being intended to be movable in rotation about a longitudinal axis, said distributor member comprising a body having a first fluid distribution channel, extending axially along the longitudinal axis, and a first chamber communicating with this distribution channel, the first chamber opening radially, such that angular positions of the body determine a passage of the fluid between an inlet and/or outlet channel, called axial, and at least one of the inlet and/or outlet channels, called peripheral, of the valve, through the first chamber and the first distribution channel.

Thus, thanks to the invention, an improvement is ensured in the compactness of the distributor member itself and that of the valve with which it is associated. Indeed, the distribution channel positioned axially along the longitudinal axis of the valve allows for an inlet and/or outlet of the fluid in the axis of the valve and not only in the periphery thereof. In this way, the size can be reduced. In addition, the distributor member, by the multiplicity of its angular positions, allows numerous possibilities for distributing the fluid when integrated with the valve in a fluid circuit.

Detailed description of the invention

As illustrated in Figures 1 and 2, the invention relates to a distributor member 10 of a valve for fluid, in particular a heat transfer liquid.

This distributor member 10 is intended to be movable in rotation about a longitudinal axis X. The distributor member 10 comprises a body 12 and may optionally comprise a first plate 14 and a second plate 16, parallel and orthogonal to the longitudinal axis X, connected by the body 12. The body 12 has lateral edges 18, located in the present example at the level of a fictitious cylinder connecting peripheral edges 20 of the plates 14, 16. It is understood that the first and second plates 14, 16, when present, define a diameter of the distributor member 10.

The distributor member 10 can be configured to rotate in a clockwise and/or counterclockwise direction.

The body 12 of the distributor member 10 further has a first distribution channel 22 for the fluid. This first distribution channel 22 extends axially along the longitudinal axis X. This means that the longitudinal axis X of rotation of the distributor member 12 passes through the distribution channel 22. Advantageously, the first distribution channel 22 is centered on the longitudinal axis X.

The body 12 also has a first chamber 24 communicating with the distribution channel 22. This first chamber 24 also opens radially.

In this way, angular positions of the body 12 of the distributor member 10 determine a passage of the fluid between an inlet and/or outlet channel, called axial 108, and at least one of the inlet and/or outlet channels, called peripheral 110a-110f, of the valve 100 (see figures 3 to 6), through the first chamber 24 and the first distribution channel 22.

The body 12 of the distributor member 10 may further have one or more second chambers 25a-25c opening radially so that angular positions of the body 12 also determine a passage of the fluid between different peripheral inlet and/or outlet channels 110a-110f of the valve 100, through the or at least one of the second chambers 25a-25c. In the examples illustrated, there are four second chambers 25a-25c.

The first chamber 24 and/or said second chamber(s) 25a-25c advantageously extend angularly around the longitudinal axis X.

The distributor member 10, in particular the body 12, has a height h, extending along the longitudinal axis X. It is understood that the height h corresponds to a height on the one hand of the first chamber 24 and on the other hand, when they exist, of the second chamber(s) 25a-25c.

Advantageously, the first distribution channel 22 communicates with the first chamber 24 over all or part of the height h of the first chamber 24. This communication between the distribution channel 22 and the first chamber 24 is done via an opening 23.

Furthermore, the distributor member 10, in particular the body 12, advantageously comprises a central part 26. The body 12 can also comprise branches 28a, 28b connected to each other at the central part 26. The branches advantageously extend substantially radially from the central part to the lateral edges 18.

The chamber(s) 24, 25a-25c are defined between two of the branches. In other words, when the distributor member 10 comprises several chambers 24, 25a-25c, the branches separate the chambers 24, 25a-25c from each other.

The branches 28a, 28b comprise walls 30a, 30b which extend along the longitudinal axis X from the first plate 14 towards the second plate 16.

The walls 30a of the branches 28a delimiting the first chamber 24 can be substantially flat.

Here, the angular amplitude of the first chamber 24 is between 35 and 45 degrees.

The branches 28b delimiting at least one of the second chambers 25a-25c can form a curved bottom 34 at the level of the central part 26. This curved bottom 34 can be concave in order to facilitate the flow of the fluid.

Here, the angular amplitude of each second chamber 25a-25c is between 70 and 90 degrees.

Advantageously, at least one of the branches 28b comprises a through channel 36 configured to connect one of the chambers with another of the adjacent chambers. With reference to the illustrated example, it is understood that the chamber 25c is composed of two half-chambers connected to each other by the through channel 36 to form an enlarged chamber, corresponding to the chamber 25c.

With reference to Figures 3 to 6, the invention also relates to a valve 100 for fluid, in particular a heat transfer liquid, which comprises a distributor member 10 as described above.

The valve 100 comprises a housing 102 defining a housing 104 for the distributor member 10. It is understood that the housing 104 then has a diameter substantially identical to the diameter of the distributor member 10, with a clearance necessary for the rotation of the distributor member 10 in the housing 104. The lateral edges 18 of the body 12 are located opposite and in the immediate vicinity, with the clearance, of an internal face of a side wall 106 of the housing 102.

The housing 102 is provided with peripheral input and/or output channels 110, opening laterally into the housing 104. In the examples illustrated, the peripheral input and/or output channels 110a-110f are six in number, namely a first input and/or output channel 110a, a second input and/or output channel 110b, a third input and/or output channel 110c, a fourth input and/or output channel 110d, a fifth input and/or output channel 110e and a sixth input and/or output channel 110f.

Each of the peripheral input and/or output channels 110a-110f is arranged as a radial projection of a side wall 106 of the housing 102. Advantageously, the peripheral input and/or output channels 110a-110f are divided into two diametrically opposite groups. It is understood, with reference to the figures, that a first group of peripheral input and/or output channels 110a-110c is positioned on one side of the housing while a second group of peripheral input and/or output channels 110d-110f is positioned diametrically opposite the first group. Each of the first and second groups may comprise three of the peripheral input and/or output channels 110a-110f. The peripheral input and/or output channels 110a-110f of the same group here extend over an angular interval of at most 120 degrees.

Depending on its angular position, the first chamber 24 of the distributor member is or is not placed in communication with one or more of said peripheral inlet and/or outlet channels. Said first chamber 24 is intended to communicate radially with the peripheral inlet and/or outlet channels 110a-110f. Advantageously, the first chamber 24 is intended to communicate with at most one of the peripheral channels 110a-110f, regardless of the angular position of the body 12 of the distributor member 10.

The second chamber(s) 25a-25c communicate radially with the peripheral inlet and/or outlet channels 110a-110f. Advantageously, the second chamber(s) 25a-25c communicate with at most two of the peripheral inlet and/or outlet channels 110a-110f, regardless of the angular position of the body 12 of the distributor member 10.

The valve 100 may comprise an actuator, not shown, for example a stepper motor, for rotating the distributor member 10 around the longitudinal axis X. The distributor member 10 may then comprise a drive shaft, intended to be engaged with the actuator.

The valve 100 may also comprise a first annular seal 50, located between the distributor member 10 and the internal face of the side wall 106 of the housing 102. This first annular seal 50 advantageously has slots 52 having an outline corresponding to an outline of an emerging part of the peripheral inlet and/or outlet channels 110a-110f in the housing 104. Preferably, the first annular seal 50 is fixedly mounted.

In order to avoid damaging the seal 50, in particular at the level of the openings 52, during rotation of the distributor member 10, the branches 28a, 28b may comprise external ends, that is to say opposite the central part 26, having a chamfer 32. In the example illustrated, only the branches 28a comprise chamfers 32. According to a preferred embodiment, the branches 28a, 28b all comprise external ends having a chamfer 32.

The valve 100 may further comprise a plate 112 which is designed to close the housing 102. This plate 112 is mounted orthogonally to the longitudinal axis X of the distributor member 10. The plate 112 may be fixed, in particular welded, to the housing 102. In the embodiment of FIGS. 3 and 4, the plate 112 is configured to be fixed to a fluid distribution support, not illustrated, in particular to a casing of such a support.

The plate 112 advantageously comprises slots 114a-114g located in the axial extension of the first distribution channel 22 and/or peripheral inlet and/or outlet channels 110a-110f. Thus, the slot 114a is located in the axial extension of the channel 110a, the slot 114b in the axial extension of the channel 110b, the slot 114c in the axial extension of the channel 110c, the slot 114d in the axial extension of the channel 110d, the slot 114e in the axial extension of the channel 110e, the slot 114f in the axial extension of the channel 110f and the slot 114g is located in the axial extension of the first distribution channel 22.

The valve 100 may comprise a second annular seal 60 configured for sealing with the distribution support. In such a case, the plate 112 advantageously comprises, on an external face, a groove 116. This groove 116 is designed to accommodate the second annular seal 60. This second seal 60 may be a flat seal in several parts, for example a part around each light 114a-114f and a part around the light 114g, as illustrated in FIG. .

Alternatively, shown in Figures 5 and 6, the valve is intended to be used autonomously, by being connected to fluid circulation hoses. The plate 112 comprises an axial inlet and/or outlet conduit 108 communicating with the first channel 22. The plate may also comprise peripheral inlet and/or outlet conduits 118a-118f communicating respectively with the peripheral inlet and/or outlet channels 110a-110f. The axial inlet and/or outlet conduits 108 or peripheral 118a-118f may be oriented along the longitudinal axis X.

The plate 112 allows interchangeability of the valve 100 according to the type of distribution support used in a fluid circuit, in particular a heat transfer liquid.

Different distribution positions of the valve 100 of FIGS. 7 to 17 are shown below in the context of an example of a heat transfer fluid circuit 200 illustrated in FIG. . Such a circuit 200 is only a non-limiting example of a circuit in which the valve 100, with its distributor member 10 according to the invention, is intended to be used.

In the following, the flows of the heat transfer fluid through the chambers 24, 25a-25c of the distributor member are represented by arrows in the corresponding figures.

In reference to the , the heat transfer fluid circuit 200 is configured to allow the thermal regulation of a battery 202 supplying a motor drive electric motor of a motor vehicle and/or an electrical assembly formed by the electric motor 204 and control electronics 206 of an electrical circuit connecting the battery 202 to the motor 204. The fluid circuit 200 may also comprise a first heat exchanger 208, in particular a cooler, a second exchanger 210, in particular a low temperature cooling radiator 210, and/or a third heat exchanger 212.

The battery 202, the electric motor 204, the control electronics 206, the cooler 208, the cooling radiator 210 and the third heat exchanger 212 are distributed over first 250a, second 250b, third 250c, fourth 250d, fifth 250e, sixth 250f and seventh 250g branches of the circuit 200, each of the branches being connected to one of the input and/or output channels 108, 110a-110f of the valve 100, for example via the plate described above.

The heat transfer fluid circuit 200 further comprises pumps 214a, 214b respectively on the fourth branch 250d and the fifth branch 250e, to drive the heat transfer fluid in the circuit 200. In particular, the pump 214a drives the heat transfer fluid from the valve 100 to the battery 202 to cool it, while the pump 214b drives the heat transfer fluid from the electric motor 204 to the valve 100.

In a first mode of operation illustrated in the and corresponding to a first of the distribution positions, illustrated in the , the heat transfer fluid circulates respectively according to two independent loops. The first of the loops comprises the second 250b and the fourth 250d branches and, in series, the sixth 250f and seventh 250g branches. The second loop comprises the third 250c and the fifth 250e branches. There is no circulation of fluid in the first branch 250a.

This first operating mode then allows cooling of the battery 202 by means of the cooler 208 alone. The electrical assembly 204, 206 is then cooled by the cooling radiator 210 alone.

In this first distribution position, the first chamber 24 connects the second 250b and fourth 250d branches. The chamber 25b connects the sixth 250f and seventh 250g branches. The chamber 25c connects the third 250c and fifth 250e branches, in particular, the fluid passes through the chamber 25c via the through passage.

In a second mode of operation, illustrated in the , corresponding to a second of the distribution positions, illustrated in the , the heat transfer fluid circulates in a single loop comprising, in series, the second 250b and third 250c branches, the fourth 250d and fifth 250e branches, and the sixth 250f and seventh 250g branches. There is no circulation of fluid in the first branch 250a.

This second operating mode then allows cooling of the battery 202 and the electrical assembly 204, 206 using the cooler 208 and/or the cooling radiator 210, the heat transfer fluid passing successively through the cooler 208 then through the cooling radiator 210 before reaching the electrical assembly 204, 206 then the battery 202.

In this second distribution position, the first chamber 24 connects the fourth 250d and fifth 250e branches. The chamber 25b connects the second 250b and third 250c branches. The chamber 25c connects the sixth 250f and seventh 250g branches.

In a third mode of operation, illustrated in the , corresponding to a third of the distribution positions, illustrated in the , the fluid circulates respectively according to two independent loops. The first of the loops comprises the second 250b and third 250c branches and, in series, the fifth 250e and seventh 250g branches. The second loop comprises the fourth 250d and sixth 250f branches. There is no circulation of fluid in the first branch 250a.

This third operating mode allows the cooling of the electrical assembly 204, 206 using the cooler 208 and/or the cooling radiator 210. The battery 202 is isolated from the electrical assembly 204, 206 and can be heated or cooled using the third heat exchanger 212, the pump 214a driving the heat transfer fluid from the valve 100 to the battery 202.

In this third distribution position, the first chamber 24 connects the fourth 250d and sixth 250f branches. The chamber 25a connects the fifth 250e and seventh 250g branches. The chamber 25c connects the second 250b and third 250c branches.

In a fourth mode of operation, illustrated in the , corresponding to a fourth of the distribution positions, illustrated in the , the fluid circulates respectively according to two independent loops. The first of the loops comprises the first 250a and second 250b branches and, in series, the fifth 250e and seventh 250g branches. The second loop comprises the fourth 250d and sixth 250f branches. There is no circulation of fluid in the third branch 250c.

This fourth operating mode allows the cooling of the electrical assembly 204, 206 using only the cooler 208. As for the third operating mode, the battery 202 is isolated from the electrical assembly 204, 206 and can be heated or cooled using the third heat exchanger 212, the pump 214a driving the heat transfer fluid from the valve 100 to the battery 202.

In this fourth distribution position, the first chamber 24 connects the fourth 250d and sixth 250f branches. The chamber 25a connects the fifth 250e and seventh 250g branches. The chamber 25c connects the first 250a and second 250b branches.

In a fifth mode of operation, illustrated in the , corresponding to one fifth of the distribution positions, illustrated in the , the fluid circulates in a single loop comprising, in series, the first 250a and second 250b branches, the fourth 250d and fifth 250e branches, and the sixth 250f and seventh 250g branches. There is no circulation of fluid in the third branch 250c.

This fifth operating mode then allows cooling of the battery 202 and the electrical assembly 204, 206 using only the cooler 208.

In this fifth distribution position, the first chamber 24 connects the fourth 250d and fifth 250e branches. The chamber 25b connects the first 250a and second 250b branches. The chamber 25c connects the sixth 250f and seventh 250g branches.

In the illustrated example, as a reminder, there are five distribution positions and they involve circulation of the fluid in at least one of the chambers 24, 25a-25c. Furthermore, each distribution position involves circulation of the fluid in the first channel 22.

In light of this example, it is understood that the invention allows, thanks to the combined use of the first chamber 24, the second chamber(s) 25a-25c and the first channel 22, several possibilities for distributing the fluid, with a reduced radial and/or axial size of the valve 100. Indeed, the position of the first distribution channel 22, for example central, makes it possible to simplify the architecture of the distributor member 10 and thus make the valve 100 more compact. In the illustrated circuit, said distribution channel is advantageously connected to the one or one of the branches of the circuit communicating with the greatest number of other branches, namely here that 250d comprising the battery 202.
