ABSTRACT:
An electric fuel pump which is self-contained in a unitary housing with a fuel inlet at one end leading to a rotary eccentric pump, the pumped fuel passing out an outlet at the other end of the housing. A relief valve in the form of a shaped plate at the pump end by-passes fuel when there is reduced demand at the outlet. The outlet end of the pump is formed as a brush holder for the electric drive motor and a magnet retainer for the field assembly. A substantially constant pressure at the outlet with varying flow demands is the function of the relief valve.
