Fuel injection valve for internal combustion engines

In a fuel injection valve for internal combustion engines, having a valve body which has a valve base body (3), a valve retaining body (5), and a lock nut (10), wherein the valve base body (3) tapers toward the combustion chamber and is braced by the lock nut (10), which fits over the valve base body (3), against the valve retaining body (5), and which fuel injection valve is disposed in a receiving bore (6, 7) of an internal combustion engine, wherein a stop face (8) is embodied on the inside wall of the receiving bore (6, 7) by a reduction in the diameter toward the combustion chamber, on which stop face an annular heel (12), embodied on an outside jacket face of the valve body by a cross-sectional reduction toward the combustion chamber, comes to rest with the interposition of a sealing disk (15), the improvement wherein the sealing disk (15), on an end face remote from the combustion chamber, has an annular rib (16) extending over at least a part of the circumference of the sealing disk (15), which annular rib in the installed state engages an undercut formed on an outside jacket face of the annular heel (12) disposed on the valve body.
