Abstract
A control device for varying the supply onset of a fuel injection pump, in which the supply rate at the lower full-load point is increased without overloading the pump at the rated capacity point. A control of this kind is effected by the use of a deflection piston as well as by use of a prestressed check valve. Regulation serving the same purpose can be achieved with the aid of an element pressure sensor and two magnet valves. The control device is intended for use in an internal combustion engine.
