The fuel pump assembly comprises a main fuel tank and an auxiliary fuel tank, the main fuel tank comprises a pump core support and a flange cover component which are connected in a clamped mode, a drainage pipe is vertically constructed on the pump core support, the upper end of the drainage pipe is communicated with a pressure relief opening of a pressure regulating valve, an ejection pipe is transversely arranged at the bottom of a fuel receiving base in a penetrating mode, and an ejection channel is formed in the ejection pipe; the inner end of the ejection pipe is communicated with the lower end of the drainage pipe, a jet flow nozzle is clamped in the ejection pipe, and the nozzle end of the jet flow nozzle faces the outer end of the ejection pipe; and the lower end of the ejection pipe is communicated with an ejection oil suction nozzle, and the ejection oil suction nozzle extends out of the lower end of the flange cover part and is communicated with an oil outlet of the auxiliary oil tank. According to the scheme, fuel oil subjected to pressure relief at the pressure valve enters the drainage pipe, under the action of the jet flow nozzle, the flow speed of the fuel oil is increased, the pressure intensity is reduced, and a low-pressure area is formed, so that the fuel oil in the auxiliary oil tank is located in a high-pressure area and flows to the low-pressure area from the high-pressure area, and the purpose that the fuel oil is sucked to a higher position from the lower position in the auxiliary oil tank is achieved.
本发明涉及一种用于摩托车的燃油泵总成,包括主油箱和副油箱,主油箱包括卡接的泵芯支架和法兰盖部件,泵芯支架上竖向构建有引流管,引流管的上端与调压阀的泄压口相通,接油座的底部横向贯穿设有射出管,射出管内形成引射通道,射出管的内端与引流管的下端连通,所述射出管的内卡装设有射流嘴,射流嘴的嘴端朝向射出管的外端;所述射出管的下端连通设有引射吸油嘴,引射吸油嘴伸出法兰盖部件的下端并副油箱的出油口连通。该方案通过压力阀处泄压的燃油的进入引流管,在射流嘴的作用下,燃油流速加快,压强减小,形成低压区,使得副油箱内的燃油处于高压区,燃油从高压区流向低压区,以达到从更低位置副油箱内吸油到更高位置的目的。
