Abstract
An oil circulating and cooling system for an internal combustion engine having an oil pump to pump the oil under pressure throughout the oil distribution system of the internal combustion engine and an oil pressure regulation circuit in parallel with the oil distribution system of the internal combustion engine. The oil pressure regulation circuit comprises a relief valve for diverting a portion of the oil from the oil pump to the oil pressure regulation circuit thereby setting the maximum value of the oil pressure throughout the oil distribution system of the internal combustion engine and an oil cooler for cooling the oil which has been diverted to the oil pressure regulation circuit. Since the oil temperature and oil pressure at the output of the oil pump increase with increased engine rpm, the oil is only cooled when the engine rpm is high.
