The valve, with an end remote from the pump, protrudes into a combustion chamber of the engine. A fuel supply line to the fuel injection pump feeds into an annular chamber encompassing the clamping sleeve and, via through openings in the clamping sleeve and inlet conduits in the pump housing, the valve can be connected to a pump working chamber of fuel injection pump.
