EP-4739893-A1 - DISTRIBUTION MEMBER FOR A FLUID VALVE

Abstract

The invention relates to a fluid valve comprising a distribution member (10), the distribution member being intended to be rotatable about a longitudinal axis, the distribution member comprising a body (12) that has: • - a first fluid distribution channel (22) extending axially along the longitudinal axis; and • - a first chamber (24) in communication with the first distribution channel (22), the first chamber opening radially such that angular positions of the body (12) determine whether the fluid passes between an axial inlet and/or outlet channel and at least one from among inlet and/or outlet channels of the valve, referred to as peripheral inlet and/or outlet channels, through the first chamber (24) and the first distribution channel (22), the total number of peripheral inlet and/or outlet channels being six.

Claims (1)

1. CLAIMS 1. Valve (100) for fluid comprising a distributor member (10), said distributor member being intended to be movable in rotation around a longitudinal axis (X), said distributor member comprising a body (12) having: - a first distribution channel (22) for the fluid, extending axially along the longitudinal axis, and - a first chamber (24) communicating with said first distribution channel (22), said first chamber opening radially, so that angular positions of said body (12) 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), through the first chamber (24) and the first distribution channel (22), said valve (100) being characterized in that the peripheral inlet and/or outlet channels (110a-110f) are six in number. 2. Valve (100) according to claim 1, wherein the body (12) has one or more second chambers (25a-25c) opening radially so that angular positions of said body determine a passage of the fluid between different of said peripheral inlet and/or outlet channels (110a-110f) of the valve (100), through the or at least one of the second chambers. 3. Valve (100) according to claim 2, wherein the body (12) comprises branches (28a, 28b) connected together at a central portion (26), said branches extending from said central portion to lateral edges (18) of said body, said branches defining each chamber (24, 25a-25c). 4. Valve (100) according to claim 3, wherein at least one of said branches (28a-28b) comprises a through channel (36) configured to connect one of the chambers with another of the adjacent chambers. 5. Valve (100) according to any one of claims 1 to 4, in which the first chamber (24) has an angular amplitude of between 35 and 45 degrees. 7. Valve (100) according to any one of the preceding claims, comprising a housing (102) defining a housing (104) for said distributor member (10), said housing being provided with said peripheral inlet and/or outlet channels (110a-110f), said peripheral inlet and/or outlet channels opening laterally into said housing. 8. Valve (100) according to any one of the preceding claims, in which the first distribution channel (22) of the valve communicates axially with the axial inlet and/or outlet channel (108). 9. Valve (100) according to any one of the preceding claims, in which the first chamber (24) is intended to communicate with at most one of said peripheral channels (110a-110f) of the valve, whatever the angular position of the body (12). 10. Fluid circuit (200), in particular heat transfer fluid, comprising a valve (100) according to any one of the preceding claims, said circuit further comprising a plurality of branches connected to said valve, a specific one (250d) of said branches being connected to said axial inlet and/or outlet of the valve, said specific branch (250d) being provided with an electrical power supply battery (202) so as to cool or heat said battery (202) using said fluid.

Description

DESCRIPTION TITLE: 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. Summary of the invention The present invention aims to overcome at least in part the drawbacks stated above and proposes for this purpose 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, so 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. The distributor member according to the invention may comprise one or more of the following features, taken in isolation from one another or in combination with one another: the body has one or more second chambers opening radially such that angular positions of the body determine a passage of the fluid between different peripheral inlet and/or outlet channels of the valve, through the or at least one of the second chambers; the body comprises branches connected to one another at a central portion, the branches extending from the central portion to lateral edges of the body, the branches each defining first and/or second chambers; the branches extend substantially radially; at least one of the branches comprises a through channel configured to connect one of the chambers with another of the adjacent chambers; the first chamber has an angular amplitude of between 35 and 45 degrees; each second chamber has an angular amplitude of between 70 and 90 degrees; the first distribution channel is centered on the longitudinal axis; the first and/or second chambers extend angularly around the longitudinal axis; the first distribution channel communicates with the first chamber over all or part of a height of the chamber, this height extending along the longitudinal axis; the second chambers are three in number; the branches delimiting at least one of the second chambers form a curved, concave bottom, at the level of the central part; the branches delimiting the chambers comprise walls extending along the longitudinal axis from a first plate towards a second plate, parallel to the first plate, the plates orthogonal to the longitudinal axis; the walls of the branches delimiting the first chamber are substantially flat; the branches delimiting the chambers comprise external ends having a chamfer. The invention also relates to a fluid valve comprising a distributor member as described above. The valve according to the invention may comprise one or more of the following features, taken in isolation from one another or in combination with one another: the valve comprises a housing defining a housing for the distributor member, the housing being provided with peripheral
