Abstract

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.
