A control arrangement for the injection quantity of an internal combustion engine in which an adjusting member for the adjustment of the feed quantity of a fuel injection pump is adapted to be adjusted by a longitudinally displaceable diaphragm bolt of a pneumatic measuring mechanism by way of a control lever, whereby the diaphragm of the pneumatic measuring mechanism is acted upon on the one side by atmospheric pressure and is exposed on the other side thereof to the pressure in a vacuum chamber connected by way of a vacuum line with a part of the suction pipe of the internal combustion engine where the vacuum in the suction pipe is being picked-up particularly in a Venturi pipe section thereof; the control lever is thereby pivotally supported with its end opposite the adjusting member of the injection pump on a part operatively connected with the engine output control member and is adapted to be adjusted about this point of pivotal support by the diaphragm-bolt engaging in the central area of the control lever; additionally, the control lever is adjustable within the pivot plane thereof by the part actuatable by the output control member of the internal combustion engine; additionally, the flow cross section of the Venturi pipe section and therewith also of the suction pipe of the internal combustion engine is not adapted to be throttled so that the cross section remains essentially constant.
