Abstract: A fuel injection valve for internal combustion engines having a valve body in which a bore is embodied, a valve seat face, at least one injection opening embodied on the end toward the combustion chamber of the bore, and at least one injection opening connecting the bore with the combustion chamber of the engine. A nozzle needle is longitudinally displaceably guided in the bore and on its end toward the combustion chamber it has a sealing face, which cooperates with the valve seat face and thus controls the at least one injection opening. The nozzle needle has a central longitudinal bore, in which an inner needle is disposed that is fixed immovably relative to the valve body. The nozzle needle is guided over at least part of its length on the inner needle, so that the nozzle needle is kept exactly centrally in the bore at all times.

Abstract: A fuel injection valve for internal combustion engines, having a valve body (3) in which a bore (7) is embodied. A valve seat face (10) and at least one injection opening (9) are embodied on the end toward the combustion chamber of the bore (7), and at least one injection opening (9) connects the bore (7) with the combustion chamber of the engine. A nozzle needle (12) is longitudinally displaceably guided in the bore (7) and on its end toward the combustion chamber it has a sealing face (217), which cooperates with the valve seat face (10) and thus controls the at least one injection opening (9). The nozzle needle (12) has a central longitudinal bore (19), in which an inner needle (14) is disposed that is fixed immovably relative to the valve body (3). The nozzle needle (12) is guided over at least part of its length on the inner needle (14), so that the nozzle needle (12) is kept exactly centrally in the bore (7) at all times (FIG. 1).
