Abstract
A spill valve for a fuel injection pump includes a valve member movable towards a seating to prevent spillage of fuel from the pumping chamber of a fuel injection pump. The valve member is actuated by a piston against which fluid pressure can be applied to close the valve member onto the seating. The movement of the valve member away from the seating is limited by a stop member but this can move to allow increased movement of the valve member when fuel at high pressure is spilled from the injection pump.
