ABSTRACT:
An injector fuel injection valve is guided at the lower end by a plastic valve guide mounted in a nozzle containing a valve seat engagable by the valve element. The valve guide includes inwardly protruding annularly spaced ribs having inner guide surfaces and defining spaced flow channels. The guide surfaces engage the circular or spherical exterior of the valve element to guide the element to properly aligned seating against the conical valve seat. The plastic or polymeric valve guide is preferably molded in place within the cup shaped metal nozzle but, if desired, the valve guide may be separately molded and subsequently inserted or snapped in place within the nozzle. A second plastic valve guide may be provided for guiding the upper end of an associated armature. A plastic or polymeric ring is molded in place or otherwise mounted within a groove around the outer surface of the armature and engagable with a cylindrical tube disposed within a main body of the injector to which the injection nozzle is secured.
