More Information
Summary:Fuel injection valve (1) has an inlet port (12) and a nozzle member (2), which are produced as deep-drawn components while being fixed to the magnetic circuit element (60). The inlet port is to be connected to a fuel distribution pipe. A nozzle member is located downstream of the inlet port. A magnetic circuit element is provided with a solenoid (44), an inner pole (63), and an outer pole (65). An armature (67) is non-positively connected to a valve needle (7a) in such a way that a valve-closing member (7) disposed on the valve needle (7a) is lifted from a valve seat surface (5) when current is applied to the solenoid. An independent claim is also included for the method for the installation of the fuel injection valve. Ein Brennstoffeinspritzventil (1), insbesondere ein Brennstoffeinspritzventil für Brennstoffeinspritzanlagen von Brennkraftmaschinen, umfaßt einen Zulaufstutzen (12) für den Anschluß an eine Brennstoffverteilerleitung, einen von dem Zulaufstutzen (12) stromabwärts angeordneten Düsenkörper (2), ein Magnetkreiselement (60), aufweisend eine Magnetspule (44), einen Innenpol (63) und einen Außenpol (65) sowie mit einem Anker (67), der mit einer Ventilnadel (7a) so in kraftschlüssiger Verbindung steht, daß bei Bestromen der Magnetspule (44) ein an der Ventilnadel (7a) angeordneter Ventilschließkörper (7) von einer Ventilsitzfläche (5) abhebt, wobei der Zulaufstutzen (12) und der Düsenkörper (2) als tiefgezogene Bauteile hergestellt sind und der Zulaufstutzen (12) und der Düsenkörper (2) an dem Magnetkreiselement (60) fixiert sind.
