摘要： An impeller includes vane grooves arranged with respect to the rotative direction. At least the radially inner side of a back surface of each vane groove is radially outwardly inclined backwardly with respect to the rotative direction. The back surface has a radially inner end and a radially outer end, which are connected via a line segment. The line segment and a radius of the impeller define a backward inclining angle α therebetween. The back surface is inclined from a thickness center of the impeller toward each thickness-end of the impeller forwardly with respect to the rotative direction. The thickness-center and the thickness-end are connected via a line segment. The line segment and the thickness-center define a forward inclining angle β therebetween. The angle α, β satisfy the following relationships: 15°≦α≦30°; β≦60°; and 1≦β/α≦4.

摘要： An ECU reduces a fuel flow rate discharged from an electric pump to the filter when a fuel temperature and a fuel pressure in the filter detected by a sensor portion drop. Since a mechanical pump continues to be driven without respect to the fuel quantity discharged from the electric pumps when the fuel flow rate discharged from the electric pump is decreased, a suction pressure is generated at an inlet of the filter. The fuel in a recirculation passage is introduced into the filter through a branch passage. As the result, relatively high temperature fuel is introduced into the filter to melt a solidified fuel causing a clogging of the filter.

摘要翻译： 当由传感器部分检测到的过滤器中的燃料温度和燃料压力下降时，ECU将从电动泵排出的燃料流量降低到过滤器。 由于当从电动泵排出的燃料流量减少时，机械泵继续被驱动而不依赖于从电动泵排出的燃料量，所以在过滤器的入口处产生吸入压力。 再循环通道中的燃料通过分支通道被引入过滤器。 结果，将相对高温的燃料引入过滤器中以熔化固化的燃料，导致过滤器的堵塞。
