Piezoelectric actuator for fuel injector utilized for fuel injection system of air-compressing and self-igniting internal combustion engine, has electrical inlets and connecting lines connected by plugging carrier and transition piece

摘要

The actuator (2) has electrical connecting lines (52, 53) guided through a transition piece (20), and electrical inlets (31, 32) guided through a line carrier (3), where the line carrier and the transition piece are plugged together along a longitudinal axis (48). The electrical inlets and the electrical connecting lines are electrically connected by plugging the line carrier and the transition piece together. Electrically conductive sockets (39, 40) are provided at the line carrier, where the line carrier is arranged on basis of plastic. An independent claim is also included for a fuel injecting valve comprising a valve closing body.
