PRESSURE REGULATOR FOR FUEL SYSTEM OF VEHICLES

摘要

This invention relates to a pressure regulator for fuel system in vehicles, which comprises; a housing (50) formed with a fuel inlet (50a) and a valve seat (52); a valve member (60) which closes and opens the valve seat (52) of the housing (d?); a disk member (70) which holds said valve member (60) while allowing vertical travel and formed with fuel hole (70a) or holes; a fixing means which fixes a part of said disk member (70) to said valve member (60); another fixing means which fixes another part of said disk member (70) to said housing (50); an elastic member (80) which supports said disk member elastically; and a cap (90) which encloses said elastic member (80) and formed with a fuel outlet (90a) which is aligned with the inlet of said housing (d?). In the fuel pressure regulator of this invention, fuel flows linearly from the inlet (d?a) on housing (d?), via fuel hole (70a) of disk member (70) to the outlet (90a) on cap.
