Piezoelectric actuator for internal combustion engine, has push rods guided in actuator movement direction through housing parts that are connected with one another after joining component parts of actuator

摘要

The actuator has a spring unit (6) arranged in an axial direction between a plate (7) adjacent to a piezoelectric component (2) and a top fixation in housing parts. Push rods (8, 9) are mounted on the plate (7), guided in an actuator movement direction through the housing parts and connected outside of the housing parts with a plate (10), where the parts are connected with one another after joining component parts of the actuator.
