    摘要: 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.

    摘要: The pre-treatment method for an electromechanical transducer is particularly suitable for polarizing a piezoelectric actuator for an injection system of an internal combustion engine. Prior to the actual operation, the transducer is actuated with an electrical pre-treatment signal, in order to set a predefined operating point in accordance with the pre-treatment signal. The pre-treatment signal corresponds substantially to the electrical actuation signal during normal operation of the transducer, in order to prevent a displacement of the pre-set operating point during normal operation of the transducer.

    摘要: A sealing arrangement of a piezoactuator (12) for a fuel injection valve of an internal combustion engine, has connecting pins (14) projecting out of the piezoactuator (12) and a head arrangement (16, 18) placed on to the piezoactuator (12), which is provided with openings (20) for the penetration of the connecting pins (14), wherein a liquid-tight sealing element (30) abuts against the outer surfaces of the connecting pins (14) on one side and also against the head arrangement (16, 18) on the other. In order to ensure a reliable seal with this arrangement, in particular also over extended periods of time, the sealing element (30) abuts against the outer surfaces of the connecting pins (14) located inside the openings (20), and sealing element sections (32) located inside the openings (20) are radially compressed in the openings.

    摘要: A fuel injector has a housing for an actuator (1), especially to a fuel injector with a connector of a contact stud support injection-molded thereto. The injector has a casing (10), disposed across at least part of the periphery of the actuator (1), and an actuator cover (20) placed on the casing (10). The actuator cover (20) is laser-welded to the casing (10) in an overlapping area (30) between the actuator cover (20) and the casing (10). According to a method for finishing the housing of a fuel injector having the aforementioned features, a laser beam used for a laser welding method is incident on the overlapping area (30) in a substantially perpendicular or substantially parallel orientation in relation to the axial direction (A) of the actuator (1) and laser-welds the actuator cover (20) to the casing (10).
