Piezoelectric actuator for fuel injector of fuel injection system of internal combustion engine of e.g. passenger car, has connecting lines mechanically and electrically connected with electrical supply lines by permanent joint

摘要

The actuator (2) has an actuator body (8), a transition piece (9), a pipe bracket (26), and electrical connecting lines (16, 18) that are partially guided through the transition piece. Electrical supply lines (15, 17) are partially guided through the pipe bracket. The pipe bracket and the transition piece are indirectly connected with each other. The connecting lines and the supply lines are mechanically and electrically connected with each other by a permanent joint.
