Abstract

A fuel injection pump for internal combustion engines has a pump housing, at least one pump piston which is rotatable and reciprocatingly movable, a cam drive which rotates and reciprocatingly moves the pump piston and includes a stationary part and a rotatable part, a fixing element which determines a rotary position of the stationary part and also radially engages the stationary part and is fixed tangentially to the stationary part, a valve operative for loading a pump working chamber limited by the pump piston during a feed stroke of the pump piston for controlling an injection-active pump piston stroke, and a mounting element which releasably mounts the fixing element on an inner side of a part of the pump housing.
