Fuel Injector With a Housing, and Method For Finishing and Labeling the Housing

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 ).
