摘要： A sealing arrangement of a piezoelectric actuator comprises terminal posts (14) projecting from the piezoelectric actuator and a metallic top arrangement (18, 22), provided with openings (28) allowing the passage of the terminal posts (14) which is emplaced on the piezoelectric actuator. In order to facilitate reliable sealing in particular also for comparatively thin top plates (18), the invention provides for emplacing on terminal post sections (30) projecting from the openings (28) a sealing element (32) which is formed from an electrically insulating and sealing material and which is positioned tight against, on the one hand, circumferential areas (34) of the terminal post sections (30) and, on the other hand, the top arrangement (18, 22), with an insulating disk (40) provided with openings allowing the passage of the terminal posts (14) and made of electrically insulating material being located between the sealing element (32) and the top arrangement (18, 22).

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).
