Actuator e.g. piezo-electric actuator, module for e.g. direct-injection diesel engine, has centering piece arranged in recess, and actuator connected with adapter by centering piece, where connection is formed as clamp-connection

摘要

The module (2) has piezo-electric actuators (22, 23), and an adapter (30) with a recess (41), in which the actuator (23) is partially inserted. A centering piece (42) is arranged in the recess. The actuator (23) is connected with the adapter by the centering piece, where the connection is formed as a clamp-connection. The centering piece circumferentially surrounds the actuator (23) in sections and cooperates with a passive area (28) of the actuator (23). The centering piece is formed from plastic.
