MOTOR DRIVEN ROTARY FUEL PUMP Abstract of the Disclosure A motor driven rotary fuel pump particularly adapted to meter fuel flow from a fuel supply line to a two-barrel carburetor of an internal combustion engine. The pump includes a rotor eccentrically mounted in a rotor chamber and having a plurality of pistons mounted in radially extending piston chambers spaced about the circumference of the rotor. An arcuate inlet slot in the hous- ing adjacent the rotor supplies fuel to the piston chambers of the rotor and the fuel from the piston chambers is dispersed into arcuate outlet slots in the housing for discharge into a two-barrel carburetor The pistons ride in engagement with a peripheral wall surface defining the rotor chamber and the piston chambers register successively with each of the arcuate slots with a dwell portion for the pistons provided by the wall surface between each of the arcuate slots. A drive connection between a drive motor and the rotor continuously urges the rotor into a sealing relation with a face of the rotor chamber.
