Abstract: Compressor for generating compressed air for a commercial vehicle, having a housing with a piston chamber in a crankcase and a dead space which is configured at least in the cylinder head. The compressor has a valve device with a valve element which has an actuating section and a shut-off body for separating the dead space from the piston chamber, wherein the shut-off body can be lifted up from a valve seat in the direction of the piston chamber in order to open the valve device. The valve element is configured in one piece with the actuating section.

Abstract: A motor vehicle clutch for frictionally connecting and separating a drive assembly to/from an auxiliary assembly, has a bearing for transferring an axial force to at least one plate spring by way of a contact surface, for opening the clutch. The plate spring has spring tongues protruding radially inward, which have recesses between each other. The bearing has pins for radially immovable and rotationally fixed immobilizing of the plate spring, which pins extend from the contact surface in the axial direction of the motor vehicle clutch and are configured to be received by the recesses between the spring tongues and to engage therewith.
