JET PUMP STRUCTURE OF FUEL PUMP MODULE

摘要

PURPOSE: A jet pump structure of a fuel pump module is provided to increase intake of fuel by increasing jet pressure by configuring a jet hole of a nozzle into a plurality of the jet holes. CONSTITUTION: A jet pump structure of a fuel pump module includes a reserve cup(110), a fuel pump(150), a fuel filter(120), a pressure controller(130) and a jet pump(140). The reserve cup forms an inhale unit for inhaling fuel of a fuel tank. The fuel pump is installed in the reserve cup and inhales fuel from the fuel tank. The fuel filter filters foreign substances of the fuel transferred to an engine from the fuel pump. The pressure controller returns the fuel for controlling fuel transfer pressure. The jet pump jets the returned fuel from the pressure controller to the reserve cup.
