Abstract
An electric fuel pump assembly comprises a flange plate assembly, a pressure adjusting valve, an oil storage barrel and a pump core. The flange plate assembly is connected with an oil tank. The pressure adjusting valve and the oil storage barrel are respectively connected with the flange plate assembly. The pump core is arranged in the oil storage barrel and is connected with the flange plate assembly. The pump core comprises an oil suction pipe, a venturi component and a quickly-inserting connector. One end of the oil suction pipe is connected with the quickly-inserting connector. The other end of the oil suction pipe is connected on the lowest point at the far end of the oil tank. The venturi component is arranged in the oil storage barrel and comprises a venturi and a non-return structure. The venturi is connected with the pressure adjusting valve. The non-return structure is connected with an oil suction pipeline of the venturi. The quickly-inserting connector is arranged on the oil storage barrel and is respectively connected with the oil suction pipe and the venturi. According to the electric fuel pump assembly, the fact that fuel is fully sucked and is provided for an engine can be guaranteed, the fact that a vehicle is started timely when the vehicle is in a low-oil-level state or a slope state is guaranteed, and service life is long.
