Abstract
A fuel delivery injector includes a housing, an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity, and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity. A magnetic assembly is fixedly positioned within the cavity, and a pumping assembly includes a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position. A valve is positioned within the piston and is movable between an open position and a closed position. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.
