Description

technical field

[0001] The invention relates to a brushless diesel injection device, in particular to a brushless diesel injection pump with high efficiency and large flow. 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 outlet plat...
