摘要

A reciprocable plunger fuel injection pump includes a plunger reciprocable in a bore. The plunger is urged outwardly by a spring which engages a spring abutment. The abutment carries a thrust member which engages the end of the plunger and in use is engaged by an actuating member such as a cam. The thrust member is held within a recess in the abutment by a resilient member. The thickness of the thrust member can be selected during assembly of the pump to the associated engine.
