Electromagnet for hydraulic valve, has pole with armature rod opening in coil core, magnetic armature on rod coil core divided near magnetic armature, and at least one electric coil near coil core

摘要

The electromagnet has a pole (1) with a rod opening (16) for an armature rod (17) in a coil core (8,9) and a magnetic armature (23) on the rod. The coil core is divided near the magnetic armature. At least one electric coil (3) is arranged near the coil core. Two mutually coaxial electric coils can be used. Independent claims are also included for a magnet pole and for a hydraulic magnetic valve.
