Abstract (en)

[origin: WO03012282A1] A fuel injection valve, in particular an injection valve for fuel injection units on internal combustion engines, comprises a piezoelectric or magnetostrictive actuator (1), arranged between a valve body (12) and an actuator head (15) and operates a valve closing body by means of a valve needle, which co-operates with a valve seat surface to form a sealing seat. A barreled sleeve (16) which is convex in longitudinal section between two diameters at the ends thereof, seals the actuator to a combustion chamber (14) and surrounds the actuator (1), whereby the barreled sleeve is non-positively connected at the ends thereof to the valve body (12) and the actuator head (15) and is tensioned along a longitudinal axis of the actuator (1).
