  • Patent number: 7906888
    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.

  • Patent number: 7784444
    Abstract: A protective cover for an actuating drive, that can be used as universally as possible, for components (14, 16) of a contacting and/or sealing arrangement of the actuating drive. The sealing arrangement is embodied in a liquid-tight but gas-permeable manner and ends in a cavity on the outer side, the cavity being covered by a cover (28) held on the actuating drive by means of a catch connection (30, 32).

  • Publication number: 20080197314
    Abstract: 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).

  • Publication number: 20080041976
    Abstract: A cover (10) is used as a protective covering for a contacting and/or sealing arrangement (3, 4) on a servo-drive (1) for actuating a fuel injection valve, wherein the cover (10) is easy to label, capable of being used in the greatest possible number of ways and has a cover body (12) in the form of a plastic injection molding with a labeling area (14) embedded in it. The plastic material of the cover body (12) is chosen for its suitability for laser welding to a fastening section (22) of the servo-drive (1), and the material of the labeling area (14) is chosen for its suitability for laser labeling purposes.
