Piezoelectric actuator module esp. for fuel injection systems of combustion engines where the actuator is under force in a housing

摘要

The module (100) has a housing (102) containing a piezoelectric actuator (108). The actuator is held inside the housing by means of a force which presses its sides from inside against the housing. This force may be generated by a spring e.g. a compression spring arranged on the inside of the housing.
