VIBRATION REDUCTION STRUCTURE OF A FUEL PUMP MODULE WHICH PREVENT THE TRANSMISSION OF VIBRATION FROM THE RESERVE CUP TO THE FLANGE

摘要

PURPOSE: A vibration reduction structure of a fuel pump module is provided to reduce the vibration transmitted from the reserve cup to the flange through a connection pipe, using damping rings in contact with the inner surface of a guide.;CONSTITUTION: A vibration reduction structure of a fuel pump module comprises a flange(10), a reserve cup(20) and a connection pipe(40). The connection pipe connects the flange and the reserve cup. The reserve cup has a guide(30) on the perimeter in which one end of the connection pipe is inserted. The connection pipe with a plurality of first damping rings(50) on the exterior of one side is inserted in the guide. The first damping rings contact in line with the inner surface of the guideline. Therefore, the vibration delivered from the reserve cup to the flange through the connecting pipe is attenuated.;COPYRIGHT KIPO 2010
