Patent ID: 6874704

Claim:
A fuel injection valve for internal combustion engines, the valve comprising a valve body ( 3 ) in which a bore ( 7 ) is embodied, on the end of which bore a valve seat face ( 10 ) and at least one injection opening ( 9 ) are embodied, which injection opening ( 9 ) connects the bore ( 7 ) with the combustion chamber of the engine, a nozzle needle ( 12 ), which is longitudinally displaceable in the bore ( 7 ) and on its end toward the combustion chamber has a sealing face ( 17 ) which cooperates with the valve seat face ( 10 ) and thus controls the at least one injection opening ( 9 ), a central longitudinal bore ( 19 ) in the nozzle needle ( 12 ), and an inner needle ( 14 ) disposed in the central longitudinal bore ( 19 ), the inner needle ( 14 ) being fixed immovably relative to the valve body ( 3 ), and the nozzle needle ( 12 ) being guided over at least part of its length on the inner needle ( 14 ), wherein the inner needle ( 14 ) comprises at least two radially outward-protruding fixation ribs ( 20 ), which rest on the inner wall of the bore ( 7 ) and thus wedge the inner needle ( 14 ) in the bore ( 7 ).
