Abstract

An actuator for actuating a fuel injection valve has a piezoactuator, enclosed in an actuator housing unit (14, 16). The housing unit has a cylindrical actuator housing (14) which is elongate in its axial direction (A) and at least partially encased by an extruded plastic coat. The actuator housing unit (14, 16), in its encased area, is provided with a ventilation aperture (20) in which a ventilation element (22) produced from a microporous material is disposed.
