Fuel injection nozzle for internal combustion engines

摘要

A valve membrane (31) has a convex curvature (40) directed toward pressure space (38) and being followed up with a fixedly clamped external edge region (41) of the valve membrane. Said valve membrane (31) external edge region (41) is followed up with a ring-shaped region (42) that is attached thereto under a first acute angle of incidence {alpha}, whereby an internal region (43) following up with the ring-shaped region (42) and being defined by an opening (39) is arranged beneath a second angle of incidence {beta}, which is less than the first angle of incidence {alpha}.
