Abstract: The invention relates to a system for circulating fluid between at least one first body or housing (2) and at least one second body or housing (3), the system comprising an arrangement of multiple fluid connections (4, 4?, 4?, 4?) between, on the one hand, the first body or housing (2) provided with at least two mutually separate openings (5, 5?, 5?, 5?) and, on the other hand, at least one second body or housing (3) also comprising mutually separate openings, each connection establishing a sealed fluid connection between an opening of the first body or housing (2) and an opening of the second body or housing (3), or of one of the second bodies or housings. Said system (1) is characterised in that each of the fluid connections (4, 4?, 4?, 4?) is rigid but hinged, and formed by successive interlocking of a rigid female tubing (7, 7?, 7?, 7?) and a rigid or diabolo pipe (9, 9?, 9?).

Abstract: An assembly has at least one battery module made up of cells oriented parallel to each other and a device for regulating the temperature of a battery module. The device has at least one substantially planar surface positioned against the respective parallel faces of the cells of the battery module and a thickness incorporating at least one circuit for distributing a heat-transfer fluid arranged opposite the respective parallel faces of at least a first group of cells. At least first respective portions of the cells of the group are opposite at least a first portion of a distribution circuit corresponding to a portion of a duct formed by a branch of a distribution circuit and at least second respective portions of the cells of the group are opposite at least a second portion of a distribution circuit corresponding to a portion of a duct formed by a branch of a distribution circuit.

Abstract: The present invention relates to a cooling module (1) for electrical battery cells, comprising a main body (3) in the form of a composite plate and incorporating at least one circuit (4) for the circulation of a heat transfer fluid, between a base plate (6) made of a rigid material with low thermal conductivity and at least one covering plate (8) made of a material with high thermal conductivity, which is intended to come into surface contact with cells of the battery to be cooled, each assembly [cover plate (8)/duct circuit (4)] forming a temperature-controlled reception site.

Abstract: The invention concerns a system for the circulation of fluid between at least one first body or housing (2) and at least one second body or housing (3), comprising an arrangement of multiple fluidic connections (4, 4?, 4?, 4??) between, on the one hand, said first body or housing (2) provided with at least two mutually distinct openings (5, 5?, 5?, 5??) and, on the other hand, at least one second body or housing (3) also having mutually distinct openings, each connection establishing a leaktight fluidic connection between an opening of the first body or housing (2) and an opening of the second body or housing (3), or of one of the second bodies or housings. In this system (1), each of the fluidic connections (4, 4?, 4?, 4??) is of a rigid but articulated type, and formed by successive nestings of a rigid female manifold (7, 7?, 7?, 7??), a rigid duct or diabolo (9, 9?, 9?, 9??) and a rigid male fitting (8, 8?, 8?, 8??).

Abstract: The present invention relates to a valve device for regulating a fluid, particularly a gaseous fluid, in a conduit portion, comprising a valve body fixed to a support spindle extending transversely into said portion and mounted with the ability to rotate therein, said conduit portion comprising, on either side of said spindle, opposing internal steps forming two bearing surface portions for corresponding edge parts of said valve body, in the closure position thereof, each step extending substantially over approximately half of the internal circumference of the conduit portion in the region of the mounting position of the support spindle.
