Abstract
A fuel injection pump of the rotary distributor type including a pump plunger the outward movement of which can be limited by an angularly adjustable stop ring to determine the maximum amount of fuel supplied by the pump. The stop ring is moveable from a first position to a second position to enable the pump to supply an excess amount of fuel for starting the engine. A first torsion spring biases the stop ring to the first position and a second torsion spring biases the ring to the second position and is stronger than the first torsion spring. Means is provided to remove the force exerted by the second torsion spring when the supply of the extra amount of fuel is no longer required. This means can be a fluid pressure operable piston.
