Abstract
A method of assembling a valve module of a fuel injector for fuel injection systems of internal combustion engines is described. The fuel injector includes an electromagnetic actuating element having a magnet coil, an internal pole, an external magnetic circuit part and a movable valve closing body which works together with a valve seat assigned to a valve seating body. The valve seating body and the internal pole are arranged in an internal opening in a thin-walled valve sleeve, and the magnet coil and the external magnetic circuit part are arranged on the outer periphery of the valve sleeve. First, the magnetic circuit part is pushed onto the valve sleeve, then the valve seating body is pressed into the internal opening in the valve sleeve, so that a fixed connection between the valve sleeve and the magnetic circuit part is achieved by simply pressing the valve seating body into position.
