Abstract

An air assist fuel injector wherein a shroud member is snapped on the outside of the valve body to provide a path for assist air to atomize the fuel exiting the injector. Located on the bottom surface of the shroud is a belleville washer to preload air deflection disks against the bottom of the valve body. Snap-on connectors cooperate with the valve body to locate and retain the shroud to the valve body.
