Abstract
A distributor diesel fuel injection pump of the spill-inject-spill type has a two-piece valve moveable relative to a valve seat to the spill-inject-spill cycles with this valve being actuated by the armature of a push type solenoid. At least the tip portion of the valve is made of steel, the remainder of the valve being formed of a compliant material so as to substantially reduce valve bounce and to permit sufficient bending of the valve to allow the armature to contact the pole surface of the solenoid.
