INLET VALVE OF FUEL PUMP MODULE, CHECK VALVE, FUEL STREAM CONTROLLER, AND FUEL PUMP MODULE

摘要

PROBLEM TO BE SOLVED: To open an inlet valve provided at one end of a jet pump piping part when the minimum amount of fuel is supplied into a tank. SOLUTION: In this fuel pump module of a fuel tank for an automobile, a check valve 67 provided at a position for taking fuel into a reservoir 22 from the jet pump piping part 62 has the inlet valve 40 for opening or closing one end of the jet valve piping part 62. This inlet valve 40 has a weight 42 for balance on the opposite side to a valve element 52 for the center of rotation. Since auxiliary moment is generated in the direction of opening the inlet valve 40 by the weight 42 for balance, the inlet valve 40 is opened to let fuel flow into the reservoir 22 even if pressure of fuel supplied into the jet pump piping part 62 is low.
