Common rail piezoelectric injector for injecting fuel into internal-combustion engine, has electrical conductor whose length is greater than minimum cable length required for electrical connection of modules around minimum distance

摘要

The arrangement has a piezoelectric actuator module (3) and an outer electrical module (4), which are electrically connected together by an electrical conductor (5) of the actuator module. The actuator module and the electrical module are detachable from each other only by disconnection of the electrical conductor to a minimum distance (deltaL) to the electrical module. The length of the electrical conductor is greater than the minimum cable length (Lmin), that is required for electrical connection of the modules, around the minimum distance.
