| 摘要 | A pump housing includes: a slide surface, along which inner and outer gears are slid; a suction guide passage, which is recessed from the slide surface and guides the fuel at a suction side; a discharge passage, which is recessed from the slide surface-and guides the fuel at a discharge side; and a communication groove, which is recessed from the slide surface and is shaped into an arcuate form that extends along a circumcircle of the inner gear. The communication groove is communicated with the suction groove and the discharge passage through two opposite groove end parts, respectively, of the communication groove. | ||||||
