Abstract
The invention relates to an electric fuel pump. The electric fuel pump comprises a pump body, a pump cover, an oil inlet pipe connector, an oil outlet pipe connector and a plunger valve, wherein an electromagnet is arranged in the pump body; a flowing gap where oil in the oil inlet pipe connector flows into the oil outlet pipe connector is formed in the part, between the electromagnet and the plunger valve, of the pump body; a control assembly eclectically connected or disconnected with the electromagnet is arranged in the pump cover; the pump body is provided with an installation assembly. The electric fuel pump has the advantages that the control assembly is used for controlling the electromagnet to vertically move in the pump body, so that the oil in the oil inlet pipe connector flows into the oil outlet pipe connector along the flowing gap between the electromagnet and the plunger valve. During working, the heat generated by the electromagnet is dissipated along with flowing of liquid, the damage to the pump body caused by the existing heating problem is effectively relieved, the loss of the pump body is reduced, and the use and heat radiation effects are good. The pump body is installed on an appointed work place through the installation assembly, and assembly and disassembly are simple.
