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.
