A governor for adjusting a controlrod stop in a fuelinjection pump for an internal combustion engine. A controlling element is provided on the controlrod stop of the fuel injection pump, to which a throttled pressure fluid is fed, the discharge of which is controlled by a proportionally operating solenoid valve. An equilibrium prevails in the solenoid valve between the magnetic field applied to the solenoid armature and the compressive forces of the pressurized fluid. Depending on the magnitude of the respective forces, a larger or smaller discharge area can be unblocked thereby releasing or spilling the pressurized fluid.
