Abstract
An injection nozzle has a nozzle body, a nozzle needle that is supported displaceably in the nozzle body, a control chamber that communicates with a fluid inlet and a fluid outlet, and a valve element that can open and close the fluid outlet. The control chamber is laterally defined by a displaceable ring which rests on the nozzle needle, and a closing spring presses the ring against the nozzle needle in fluid-tight fashion.
