Fuel injection valve for e.g. fuel injection systems of internal combustion engines has inlet port and nozzle member, which are produced as deep-drawn components while being fixed to magnetic circuit element

摘要

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.
