Fuel injection valve for internal combustion engine has threaded rod as spiral forming element

摘要

The valve (1) includes a valve closing body (4) linked to a valve needle (3) and acting with the valve seat surface (6) of a valve seat body (5). The spiral-creating element is downstream of the sealing seat with its central axis enclosing an angle other than zero with the central axis (39) of the valve. A threaded rod (36) is pressed into the valve seat body to serve as a spiral forming element.
