  • Integral engine oil pump and pressure regulator
    Patent number: 5085187
    Abstract: A combination gear type oil pump and pressure regulator is disclosed, particularly for a lubricating system of an internal combustion engine. Elements of a gear type pump are housed within an internal recess in the engine crankcase. An end cover is positioned between an enlarged portion of the crankshaft and gear elements and is biased thereagainst by a carefully selected spring which is positioned between the cover member and the enlarged crankshaft portion so that when a predetermined high pressure is formed at the pump outlet, the spring allows the end cover to move away from the pump elements to relieve the pressure by spillage in to the engine crankcase.
