Beschreibung
Zusammenfassung:	A fuel injection nozzle (1) with controlled fuel outlet, especially for air-compressing, self-ignition internal combustion engines is proposed, which has a nozzle body (2) with two or more injection apertures (3), in which spring-loadable individual valve elements (4a, 4b) preferably with tapered valve seat (6a, 6b) are arranged so that they are axially movable and control the injection apertures (3). The individual valve elements (4a, 4b) can be acted upon by fuel feed pressure by way of a pressure chamber (7, 8, 9) provided in the nozzle body (2) and according to the invention are arranged concentrically to the longitudinal axis of the nozzle body (2.1) in a common nozzle chamber (2.2).
