Abstract:
A fuel pump for a fuel system includes a nozzle, a venturi, a pump inlet and a flow controller. The nozzle has an orifice through which fuel is ejected and the venturi is downstream of the nozzle and has an inlet through which fuel discharged from the orifice flows, a passage downstream of the venturi inlet through which fuel flows to create a drop in pressure in the area of the venturi, and an outlet through which fuel is discharged from the venturi. Fuel is drawn through the pump inlet by the drop in the pressure created in the area of the venturi and the flow controller is downstream of the outlet and has a chamber in which fuel from the venturi outlet is received. The flow controller causes fuel to fill the venturi to ensure performance of the fuel pump.
