Abstract

A control apparatus for limiting the fuel supply quantity of a fuel injection pump for internal combustion engines such as Diesel engines or the like by means of which an automatically controlled additional starting quantity of fuel is variable in accordance with temperature which comprises a limit stop displaceable by the pressure of a control medium and connected with a control piston and including a starting detent which varies its position in accordance with temperature; the limit stop in its first terminal position being arranged to determine the starting setting and in its other terminal position under the control of the pressure of the control medium, being arranged to determine the full-load setting of the fuel supply quantity adjustment member of the injection pump, a starting setting for a warm engine being controlled by the starting detent which limits the starting setting to the full-load setting or below.
