Problems solved by technology

[0002] In the low-pressure electric fuel pump of the prior art, the pump body usually adopts a double-roller structure, which is not compact enough, which makes the entire oil pump motor load too large and reduces the effective output power of the motor; the width of the oil circuit of the electric fuel pump in the prior art , depth and thickness of the rollers are unreasonably designed, which will easily lead to unsmooth exhaust of the fuel pump oil circuit, resulting in slow oil absorption and reduced efficiency of the fuel pump. In addition, the inlet and outlet plates and rollers of the low-pressure electric fuel pump in the prior art are made of engineering plastics (i.e. reinforced polyoxymethylene) structure, which makes the friction between the roller and the oil inlet and outlet plate larger, and the noise is too loud when running, which affects the performance of the fuel pump and reduces the service life.

Abstract

The invention discloses a high-efficiency large-flow brushless diesel oil injector, comprising a casing, a rear cover, a decompression valve, a rotor, a rotor core, a connector, a dead axle, a jump ring, a locking plate, a controller, a controller seat, a circuit cover plate, a supply socket, a stator assembly and a gear. According to the invention, the high-efficiency large-flow brushless diesel oil injector employs a five-roller pump body structure, so oil supply pressure and oil supply flow of the injector are greatly improved; intermittent working time of the injector can be set through a timing controller of the intelligent controller, so work efficiency of the injector is substantially enhanced; moreover, the injector has the advantages of a compact structure, small noise and a prolonged service life.

Description

technical field [0001] The invention relates to a brushless diesel injection device, in particular to a brushless diesel injection device with high efficiency and large flow rate. Background technique [0002] In the low-pressure electric fuel pump of the prior art, the pump body usually adopts a double-roller structure, which is not compact enough, which makes the entire oil pump motor load too large and reduces the effective output power of the motor; the width of the oil circuit of the electric fuel pump in the prior art , depth and thickness of the rollers are unreasonably designed, which will easily lead to the unsmooth exhaust of the fuel pump oil circuit, resulting in slow oil absorption and reduced fuel pump efficiency. In addition, the inlet and outlet plates and rollers of the low-pressure electric fuel pump in the prior art are made of engineering plastics (i.e. reinforced polyoxymethylene) structure makes the friction between the roller and the oil inlet and outl...
