ABSTRACT:
A fuel injection pump for internal combustion engines, of the distributor type, having a reciprocating and simultaneously rotating pump piston as well as a governor slide adjustable relative thereto as a function of load, the injection quantity at any time being dimensioned on the basis of the position of the governor slide. For controlling an exhaust gas recirculation valve as a function of the load range or the particular injection quantity, the injection pump has a pressure switch for controlling an electrical signal in the partial-load range. The pressure switch can be made to communicate with the pressure-carrying suction chamber via a line in the housing and a conduit in the pump piston, the inlet of which conduit is controlled by the governor slide such that it is opened only whenever the outlet of a relief conduit is closed by the governor slide.
