Tubular construction element for injection valve, has pipe whose grip surface is less than that of another pipe in overlapping area, where grip surface is provided between former pipe and grip element

摘要

The element (100) has pipes (101, 102) firmly bonded and connected with one another. One of the pipes comprises a grip element (106) formed in a cylindrical overlapping area (103). The pipes are actuated and connected with one another via the grip element. A grip surface of the other pipe is less than that of the former pipe in the overlapping area, where the grip surface is provided between the latter pipe and the grip element. The grip element is designed as a weld seam. The grip element is vertically arranged or parallel to a symmetry axis of the overlapping area. An independent claim is also included for a method for manufacturing a construction element for an injection valve.
