ABSTRACT:
A generally frusto-conical contaminant particle deflector is mounted within a valve body of an automotive engine fuel injector, surrounding a fuel injector valve element. An inner clearance space between the valve element and an open end of the deflector receives fuel flow when the injector valve element is moved to allow fuel flow. Contaminant particles are caused to move along a path extending radially out of the fuel stream and into a dead zone outside the perimeter of the deflector where they tend to remain so as to avoid any effects on the performance of the fuel injector.
