Fuel i.e. diesel, injecting valve i.e. injector for fuel injection system of internal combustion engine of e.g. passenger car, has magnet coil supplied for actuation of nozzle needle such that repulsion of anchor is caused by magnet coil

摘要

The valve (1) has a solenoid valve and a servo control circuit (15) arranged in a valve housing (2). The solenoid valve controls a nozzle needle (7) by the servo control circuit, which co-acts with a valve seat surface (5) at a sealing seat. The solenoid valve has a partial permanent magnetized anchor (28) and a magnet coil (32) attached to the anchor. The magnet coil is supplied for actuation of the nozzle needle such that repulsion of the anchor is caused by the magnet coil. The anchor is connected with a non-magnetic plate that is made of aluminum or austenitic steel.
