ABSTRACT:
A residual pressure control valve which is interposed between a fuel injection pump and a nozzle includes an annular valve element which is biased by a spring into contact with a seating surrounding a port connected to the pump. Slidable in the valve element is a piston which is resiliently biased away from the seating. The piston has a groove communicating with the port and the valve element has a port which is uncovered to the groove upon movement of the piston relative to the valve element against the action of its resilient loading.
