Abstract
A fuel injection nozzle, in particular pump nozzle, includes a nozzle needle loaded by a spring in the closing sense. The nozzle has a pressure space, located upstream the seat of the nozzle needle, in open connection with the storage space of a yield piston. The yield piston is shiftable within a guide bore and loaded by a spring in direction towards the storage space. The yield piston is subjected at its piston surface, located opposite the storage space to the pressure prevailing within an attenuating space, which can be filled with fuel. The attenuating space is, via a throttle cross-section, in connection with an outlet and/or with another space.
