Fuel injection valve for direct fuel-injection IC engine has piezoelectric or magnetostrictive actuator coupled to valve closure element via valve needle with operating sleeve between actuator and valve needle
Fuel injection valve for direct fuel-injection IC engine has piezoelectric or magnetostrictive actuator coupled to valve closure element via valve needle with operating sleeve between actuator and valve needle
The fuel injection valve (1) has a piezoelectric or magnetostrictive actuator (32) for operation of a valve closure element (11), cooperating with a valve seat (12), via a valve needle (10). The end face (33) of the actuator cooperates with a disc-shaped support body (20) having at least one opening (24a) for passage of a segment (25a) of an operating sleeve (26), extending between the opposite end of the actuator and the valve needle.
