Abstract
A fuel pump having a housing defining a pump chamber and an inlet and outlet fluidly connected to the pump chamber. A one way check valve is disposed fluidly in series between the pump chamber and the outlet and is oriented to allow fluid flow from the pump chamber and to the outlet when the check valve is open. A venturi tube is fluidly connected in series between the pump chamber and the outlet which effectively dampens noise pulsations. An inlet valve to the pump chamber has an anchor attached to a valve member and the stationary core. A conical surface on the core abuts against a complementary conical surface on the anchor when the valve is either in its fully open or fully closed position.
