Abstract

The invention relates to a control apparatus for the variation of the onset of supply by a fuel injection pump having an adjustment piston engaging the piston cam drive, the adjustment piston under rpm-dependent pressure being adjustable counter to a restoring force by a fluid located in a work chamber of the adjustment piston, and an assembly for prolonging the supply time and at least during pump supply on the basis of the restoring and reactionary force including displacing the adjustment piston counter to the fluid pressure.
