Electric fuel pump assembly of one-piece automobile

Abstract

The invention relates to an electric fuel pump assembly of a one-piece automobile. The electric fuel pump assembly mainly solves the technical problems that the existing fuel pump assembly is of an open structure and is connected through a connection pipe and a wiring harness, easily resulting in unreliable connection, leakage, weak vibration resistance and the like. The electric fuel pump assembly of the one-piece automobile is characterized in that a sealed filter housing and an upper cover fixedly connected with the filter housing are arranged at an opening of the cleaner housing; the top end of the upper cover is fixedly connected with a flange; an oil delivery pipe connected with a spraying pipeline of the automobile is arranged at the top end face of the flange; the oil delivery pipe is communicated with a connection pipe inside the upper cover; the connection pipe is connected with a fuel pump outlet inside the filter housing; a voltage stabilizer is arranged inside the upper cover; an inlet of the voltage stabilizer is communicated with the connection pipe, and an outlet is arranged outside the upper cover and communicated with the external part. The electric fuel pump assembly of the one-piece automobile has the beneficial effects that the filter housing is sealed through the upper cover below the flange and the flange is fixedly connected with the filter housing, so the flange and the filter housing can form an integral structure.

Description

technical field [0001] The invention relates to a gasoline pump, more specifically to an integrated automobile electric fuel pump assembly, which is mainly used in the technical field of automobile engine fuel supply systems. Background technique [0002] Electric fuel pumps are mainly used to provide fuel under certain pressure for automobile fuel injection systems. There are filter housings and no filter housings, with sensors and without sensors, with pressure regulator valves and without pressure regulator valves, etc. These fuel pumps are somewhat different in terms of materials and functions, but these car electric The fuel pump assembly is an open structure formed by flange parts and pump core parts, which are combined by guide rods, buckles, springs, oil outlet / return connecting pipes and connectors. It is powered by wire harness connection. Although the open structure is easy to produce and assemble, it is inevitable that bumps will occur during the driving process...
