Abstract: An air filter element (10) has a substantially planar configuration and comprises at least two pleated filter media (12, 12?), said pleated filter media (12, 12?) being arranged side by side and attached to each other in a permanent way by a connecting member (16) connecting facing longitudinal edges (14, 14?) of said filter media (12, 12?).

Abstract: Anti-noise device for an internal combustion engine (9) equipped with a turbocompressor (10) for supercharging includes a turbine (11) placed in the exhaust gas flow and driven by these gases with the turbocompressor (10) connected by a shaft (13) to a compressor (14) mounted in the air intake conduit (3) of the engine (9). The anti-noise device includes a hinged flap (4) mounted within the air intake conduit (3) of the engine (9), upstream from the compressor (14) and capable of closing this conduit (3) under the action of a gaseous reflux coming towards it.

Abstract: Disclosed is a heat transfer module (3) for battery cells includes a plastic frame (4) having a supply conduit and an exhaust conduit (13b) for a heat transfer fluid. Two heat transfer members (12a, 12b) contacting a respective battery cell. The heat transfer members (12a, 12b) are sealingly attached to opposite faces of the frame (4), and at least one heat transfer channel (15) formed between the frame (4) and one of the heat transfer members (12b) transporting the heat transfer fluid from the supply conduit to the exhaust conduit (13b). Also disclosed is a battery assembly having a plurality of such heat transfer modules (3).

Abstract: A closure device with a pressure valve in which the closure device is provided in the form of a protective cap (1) which has a groove (2) on its outer periphery. At least one discharge opening (31, 32) for a fluid is formed inside the groove and communicates with the interior of the vessel to be closed by the closure device. Both lateral arms (41, 42) of an elastically deformable clip (4) are forcibly inserted into the groove. At least one of these arms (41, 42) is provided with a seal (51, 52) which seals the fluid discharge opening (31, 32) in order to ensure a tight seal when the pressure difference between the interior of the vessel to be closed and the exterior environment is less than a first predetermined value, and which opens this opening when the pressure difference is greater than a second predetermined value.
