Title: FUEL DELIVERY INJECTOR
Abstract:
A fuel delivery injector includes a housing, an end cap including 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 fixedly positioned within the cavity, and a pumping assembly including a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position and a valve assembly including a biasing spring is positioned between an inlet chamber and an outlet chamber. The end cap includes a protrusion extending therefrom and terminating at an end face, the end face proximate the magnetic assembly and the protrusion is configured to redirect fuel vapor toward the outlet port.
