The oil pressure regulator serves as safety valve preventing the high pressure oil discharged from the oil pump to rise above a specified value by means of the adjusting valve. The engine is equipped with an oil filter assembly incorporating a removable type element. The function of the oil cleaner is to filter the engine oil flowing thru the filter from the oil pressure regulator, and removing any foreign element contained in the oil.
