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.

An arrangement for heating the lubricating oil contained within an oil reservoir of a machine or of an internal combustion engine of a motor vehicle, the machine or engine having a lubricating oil distribution system including means for circulating the lubricating oil at a predetermined pressure level from the oil reservoir into pressurized oil lines of the machine or engine, a heating system including a hydraulic pump for suctioning the oil from said reservoir and returning it thereto through an oil conduit into which said pump is coupled, at least one operating element coupled into said conduit at the pressure side of said pump for constricting the flow of oil through said conduit, said pump being coupled with a source of power to be thereby driven, said pump having a capacity to produce a pressure of about one order of magnitude higher than said predetermined pressure level effected by said circulating means, said source of power comprising one of said engine and a driving motor coupled with an auxiliary power source, a first releasable coupler located between said engine and said pump and a second releasable coupler located between said pump and said auxiliary power source for selectively coupling said pump with said engine or with said auxiliary power source for regulating said heating system as said pump is selectively driven by said engine or by said motor or by neither said engine nor said motor, whereby the temperature of the oil within said reservoir may be controlled before and after operation of the machine or engine.
