Injection valve e.g. injector, for injecting fuel in fuel injection system of automatic ignition internal combustion engine of motor vehicle, has bender actuator bendable corresponding to displacement of closing body in bending directions

摘要

The valve (1) has a piezoelectric actuator (6) arranged in a housing (2), and a valve closing body (21) indirectly fixed by the actuator. The valve closing body is in contact with a valve seat surface (22) to form a sealing seat. A bender actuator (30) is provided with a piezoelectric element (32) and bendable corresponding to the displacement of the valve closing body in bending directions (41, 42). The bender actuator is indirectly connected with the housing at a stationary end (45) that is connected with a nozzle body (4) or a valve housing part (3).
