Abstract (en)

[origin: DE19912666A1] The invention relates to a fuel injection valve (1), especially an injection valve for fuel injection systems, comprising a fuel admission tube (4) for supplying fuel, a piezoelectric or magnetostrictive actuator (13), which is sealed against the fuel by a sealing (14, 16, 20, 21), in addition to a valve closing body (6) actuated by the actuator (13) by means of a valve needle (5) and cooperating with a valve seat surface (8) to form a sealing seat. The sealing (14, 16, 20, 21) has a sealing plate (14) on the admission side, which is mounted between the fuel admission pipe (4) and the actuator (13) and an actuator casing (20) that is elastically deformable in longitudinal direction and that is connected to the sealing plate (14) on the admission side.
