Abstract: The present invention relates to a high-pressure fuel pump for a direct injection type LPI (low-pressure injection) system which includes a body having an inlet, an outlet, and a collection port on the lateral surface; a bracket joined to the bottom of the body and including an inner suction means generating force for sucking fuel; and a flow-rate control valve joined to one side of the body and controlling supply and discharge pressure of the fuel. The inlet and the collecting port are connected to an entry-side check valve which is opened and closed by the flow-rate control valve. By using the high-pressure fuel pump for the direct injection type LPI system, an effect of generating high pressure by rapidly collecting LPG fuel including air bubbles generated by the vaporization of the LPG fuel due to heat, which is generated by the operation of the flow-rate control valve, in a cylinder and then sufficiently pressing the rest of the LPG fuel at a preset high pressure, is obtained.
Abstract translation: 本发明涉及一种用于直喷式LPI（低压喷射）系统的高压燃料泵，其包括在侧面具有入口，出口和收集口的主体; 连接到所述主体的底部并且包括产生用于吸入燃料的力的内部抽吸装置的支架; 以及与主体的一侧连接并控制燃料的供给和排出压力的流量控制阀。 入口和收集口连接到由流量控制阀打开和关闭的入口侧止回阀。 通过使用用于直接喷射型LPI系统的高压燃料泵，通过快速收集LPG燃料产生高压的效果，LPG燃料包括由于由于热而产生的LPG燃料的蒸发而产生的气泡 流量控制阀，然后在预定的高压下充分按压其余的LPG燃料。
