Solenoid valve for actuation of fuel injector in high pressure accumulator injection system for self-igniting internal combustion engine, has magnet sleeve made of highly permeable material e.g. chromium steel, and including pole surface

摘要

The valve has a magnet sleeve (10) that encloses a magnet core (12) into which a powered solenoid coil (16) is inserted. The powered solenoid coil cooperatively works with an anchor (22) that is connected to an anchor bolt (24) or guided into the bolts in relocatable manner. The magnet sleeve is made of highly permeable sleeve material such as roller bearing steel e.g. chromium steel, and machining steel and includes an integrated pole surface. The magnet core lies at a front sided contact surface and a peripheral sided contact surface of the magnet sleeve.
