Abstract

An arrangement for heating the oil contained within an oil reservoir of a machine or of an internal combustion engine of a motor vehicle includes a hydraulic pump for suctioning the oil from the reservoir and returning it thereto through an oil conduit into which the pump is coupled. At least one operating element in the form of a throttle is coupled into the conduit at the pressure side of the pump for constricting the flow of oil through the conduit, and the pump is coupled with a source of power to be thereby driven. Thus, the temperature of the oil within the reservoir may be elevated by operation of the pump together with the operating element for improving upon the startability of the machine or engine and for sustaining early operation after the start of the machine or engine.
