Abstract: The invention relates to a compartment for a device (16) for storing electrical energy for a motor vehicle, said compartment being arranged to receive at least one cell (14) for storing electrical energy, said compartment comprising: —a bottom wall (26), the bottom wall preferably comprising a composite material, —a side wall (28) connected to the bottom wall, —a channel (50) for circulating a cooling fluid, said channel being at least partially formed by the bottom wall, —a fluid connection element (100) designed to allow the channel to be connected with an external cooling fluid circuit, the connection element being at least partially overmoulded with the bottom wall or the side wall.

Abstract: A journal configured to be driven in rotation in a housing of a turbine engine, or for an aircraft, the journal including: a circumferential main body including plural ventilation openings configured to allow plural axial airflows to circulate from upstream to downstream in the turbine engine, two consecutive ventilation openings being connected by a connecting segment, and a circumferential ring for recovering a flow of lubrication oil, which ring is rigidly connected to the main body and is radially inside the ventilation openings, the circumferential ring including plural radial discharge openings for allowing plural radial flows of oil to be discharged towards the outside, each discharge opening being radially aligned with a connecting segment of the main body to allow each flow of oil to be discharged radially between the airflows.

Abstract: A turbomachine assembly in which a foil is configured to cover mainly one of bulbs of a disc and to be held, radially with respect to the disc, by the bulb of the disc and a pocket for a blade that can collaborate therewith, when these two are effectively collaborating, and the bulb of the disc includes at least one longitudinal cavity configured to form, with the foil, when the foil is covering the bulb of the disc, a secondary passage through which a secondary cooling air flow can pass.
