Beschreibung
Zusammenfassung:	A pump nozzle for an air-compressing injection internal combustion engine with a mechanically actuated pump piston and with an inlet bore connected with the pump working space, through which fuel is fed to a nozzle needle, as well as with a return bore for leakage oil and a control device influencing the fuel delivery; a valve which is actuated in the rhythm of the engine and which with an increasing fuel pressure separates the inlet line from the pump working space is arranged in the flow path of the inlet bore upstream of the pump working space, whereby the closing position of the valve is lifted by opening of a discharge bore leading to the return bore.
