ABSTRACT:
A compact pump and motor assembly adapted for use as a fuel controller for an internal combustion engine fuel metering system. The assembly contains an electric motor, an interface housing assembly at one end of the electric motor and a pump housing assembly disposed on the side of the interface housing assembly opposite that of the motor. The motor shaft extends through the interface housing into a pilot hole in the pump housing and drives a pumping means contained within a pumping chamber defined by the pump housing and the interface housing. An inlet port, an outlet port, and a return port are provided in the pump housing. An inlet passage extends from the inlet port through the gear pump housing and the interface housing into a vapor separation chamber contained within the casing of the motor, the motor being of the wet type. A passage in the interface housing extends from the vapor separation chamber to the inlet of the pumping chamber. An outlet passage in the pump housing extends from the outlet of the pumping chamber to the outlet port. A passage shunting the pumping chamber extends in the interface housing and the pump housing from the separation chamber to the return port, and contained therein is a low pressure regulator valve which regulates pressure in the vapor separation chamber. A further passage extends in the pump housing from the pumping chamber outlet to the return port and a valve assembly is contained therein for diverting a portion of the pump output to the return port under certain conditions at the pumping chamber outlet.
