Zusammenfassung:	PURPOSE: An engine oil pump is provided to supply lubricating oil with specific oil pressure without pulse by a screw rotor, to control noise of an engine and to improve endurance of the engine. CONSTITUTION: An engine oil pump comprises an oil feed hole(3) having a hollow shape by being mounted on a side portion of a cylinder block(1); an oil fan connected to a strainer by a suction pipe(5); a discharging pipe(7) connecting the oil cooler and the oil feed hole; a screw rotor(9) rotationally inserted to the oil feed hole; a first discharging port(11) connected to the discharging pipe; a second discharging port(13) formed by penetrating plural holes along a circumference; a drive gear(15) rotating the screw rotor by receiving power from the engine of the cylinder block; a bypass pipe(17) formed on a side of the discharging pipe; a safe valve(19) connected to the bypass pipe; and metal bearings(21,23) sealing by forming a frictional face on the oil feed hole on a rear and front sides of the screw rotor.
