Title: Motor type fuel pump
Inventor: KUSAKAWA YUKIO
IPC: F02M37/08
Filed: 1982-01-12
Abstract: PURPOSE:To obtain a miniaturized pump for a fuel injection control device, having high efficiency and low electrical power consumption, by constituting the pump such that is of non-displacemnt and non-multistage type having one impeller. CONSTITUTION:A single closed-vane type regenerative pump having an impeller and a pump chamber is used for a fuel injection pump, having 35 to 60 numbers of grooves and a 250mu gap between the impeller and the inner wall of the chamber. When the impeller 3 rotates together with the output shaft 5 of a motor body 4, fuel sucked through a suction port 2 travels through a fuel pressure-feed gap 21 under the torque of the grooves 36 which are radially arranged in the outer periphery of the impeller 3, so that the pressure of the fuel is more and more increased and then blows into a linear part 30. At this time, since a part of the fuel which flows circularly, is ejected in the tangential direction, loss due to the change of the flow direction is small and it contributes to improvement in pump efficiency. Further, due to the tangential direction, the amount of material 1a for forming a pump chamber may be less.
