发明名称 ENGINE WITH OIL PUMP MUFFLER AND NOISE DAMPER
摘要 A wrap-around cover or noise muffler of oil and temperature resistant noise absorbing resilient elastomer covers the front and sides of a front mounted engine oil pump forming a pump and muffler assembly. The muffler absorbs vibrations and reduces the transfer of noise frequencies from the oil pump to an engine front cover that covers the pump. Additionally, the front of the muffler is shaped to fill the gap and engage the front cover in compression between the oil pump and the rear surface of the front cover, thereby damping vibrations of the front cover adjacent to the oil pump and to an accessory drive pulley that rotates ahead of the front cover for driving accessories.
