An oil supply system for a machine, such as for a power unit of a motor vehicle, with a module body made of plastic including a collection tank which is divided into a prechamber and a main chamber. A predelivery pump can extract oil from the prechamber and pump it into the main chamber, a main delivery pump can extract oil from the main chamber and pump it to the machine, and a return line can return oil from the machine to the prechamber and/or the main chamber. A power unit for a motor vehicle can include such an oil supply system, wherein a predelivery suction opening is arranged on the floor of the prechamber and a main delivery suction opening is arranged on the floor of the main chamber, and the power unit is configured to be mounted in the motor vehicle with an orientation such that a line running through the two suction openings is arranged approximately parallel to the transverse axis of the vehicle.

A central release mechanism for a pneumatic clutch actuating device has a cylinder housing, which, about a central axis, delimits a ring-shaped pressure chamber wherein a ring-shaped piston which can be pneumatically pressurized via the pressure chamber and which is operatively connectable to a clutch is guided so as to be displaceable along the central axis. In the pressure chamber, between the ring-shaped piston and a base of the cylinder housing, a preload spring arrangement braces the ring-shaped piston and the cylinder housing apart from one another. A movement of the ring-shaped piston relative to the cylinder housing is detectable with a sensor arrangement which has a position detector and a position encoder. The preload spring arrangement has a multiplicity of distributed preload springs, angularly spaced apart from one another, about the central axis. Between the preload springs as viewed in a circumferential direction about the central axis, at least a part of the sensor arrangement is arranged in the region of the pressure chamber providing a compact construction.
