A governor for a fuel injection pump includes a plurality of weights which effect axial movement of a member which in turn is coupled to the fuel control rod of the pump. Movement of the member by the weights is opposed by a spring, the force exerted by which can be adjusted by means of a roller interposed between the spring and a ramp defined on an arm. The reaction applied to the arm is taken by a coiled compression spring which when the speed of the engine is above a predetermined value, and when the roller is set so that maximum fuel is supplied to the engine, compresses to reduce as the engine speed continues to increase, the amount of fuel supplied to the engine.
