  • Patent number: 4209284
    Abstract: A fuel system for a motor vehicle wherein an electric motor-driven two-stage fuel pump has a motor with a cylindrical flux carrier having a pair of segmented permanent magnets disposed therein in a manner to provide a pair of axial fuel flow paths intermediate said magnets and interior to the flux carrier. The motor armature has a drive shaft with a D-shaped section which supports a pair of pump impellers each having a central D-shaped aperture complementary to the D-shaped section of the drive shaft. The shaft has a single bearing intermediate the armature and impellers so that the impellers are supported by the D-shaped drive connection in a manner which permits axial alignment of the impellers relative to the stationary elements of the pump.
