Abstract
A fuel injection pump for internal combustion engines having an injection timing adjustment by means of a hydraulically actuated piston is proposed, the injection timing adjustment being loaded by two restoring springs. Between the two springs, which have different forces, there is a common spring support plate. The variable functional path of the springs is determined by means of a stop and a coupler member.
