ABSTRACT:
A fuel injector includes an injector body and a three-way control valve having a valve element movable between first and second positions in the injector body. A check is disposed in the injector body and is movable to inject fuel when the control valve is in the second position and to block fuel injection when the control valve is in the first position. An actuator is selectively operable to move the valve element between the first and second positions. The injector includes a single clearance fit located in the control valve wherein the clearance fit is not exposed to a substantial pressure differential when the control valve is in the first position.
