Electromagnetic injector control valve or pressure regulator valve for a high pressure fuel accumulator

摘要

The valve has a casing with upper portion (1) and a lower portion (2), an electromagnet formed of an electromagnetic coil (25) housed in a yoke (24), and an armature (22). An abutment disk (28) is provided between a transverse face of the armature and a transverse face of the yoke, and is made of magnetized or magnetizable material. A bearing surface of the abutment disk is reduced by cutouts. The abutment disk protrudes laterally beyond the yoke, and transmits impact forces applied against the casing during operation.
