燃料泵及燃料泵模块
摘要：
燃料泵(10)被与具备过滤器侧结合部(94)的吸滤器(90)结合，将由该吸滤器(90)过滤后的燃料吸入，所述过滤器侧结合部(94)具有筒孔部(95)和从该筒孔部(95)的内周壁(95a)向内周侧突出的凸部(96)。燃料泵(10)具备：吸入口部(74)，具有在吸滤器(90)侧开口的多个吸入开口孔(76)，从该多个吸入开口孔(76)吸入燃料；泵侧结合部(78)，被设置在比该多个吸入开口孔(76)更靠外周侧，被与过滤器侧结合部(94)结合。泵侧结合部(78)具有与内周壁(95a)匹配的形状的外周壁(78a)、和通过从该外周壁(78a)向内周侧凹陷从而供凸部(96)嵌入的凹部(79)。
摘要（英）：

A fuel pump is connected to a suction filter which is provided with a filter connecting portion having a cylindrical hole and a projecting portion protruding radially inward from an inner peripheral wall of the cylindrical hole. The fuel pump suctions the fuel filtered by the suction filter. The fuel pump is provided with a suction port having multiple suction openings at a side of the suction filter so as to suction the fuel therethrough, and a pump connecting portion provided at outer side of the multiple suction openings and connected with the filter connecting portion. The pump connecting portion has an outer peripheral wall of which outer shape corresponds with a shape of the inner peripheral wall, and a dent portion denting inward from the outer peripheral wall, which the projecting portion is engaged with.
