Abstract
A fuel injection nozzle for air-compressing internal combustion engines, especially a throttle-pin nozzle wherein a nozzle needle, urged against a conical valve seat by a compressing spring, is lifted with respect to the compression spring by a feed pressure in the fuel. A device is provided for rotating the nozzle needle about its longitudinal axis. The device for effecting rotation is arranged between the nozzle needle and a spring disk and is fashioned in such a way and controlled by a stroke motion of the nozzle needle in such a manner that the nozzle needle, during each closing stroke, is further rotated stepwise in one direction by a specific peripheral angle.
