PURPOSE:To reduce size by forming the valve body of pulse reducing valve placed in fuel delivery path integrally with housing while inclining against the outer end face of housing thereby shortening the axial length of rotor. CONSTITUTION:A rotary pump P and a motor M are contained in a housing 22 having a fuel suction pipe section 25 at one end and a fuel delivery pipe section 63 at the other end. A pulse reducing valve (V) is placed in a fuel delivery path 64 communicating with said section 63. The valve body 66 of said valve (V) is formed integrally with the housing 22 while inclining against the outer end face of housing 22. In such a manner, axial length of rotor shaft 36 of fuel pump system is shortened to reduce size while to eliminate seal between the housing and valve body. |
