Magnetic coil for actuating electromagnetic valve, has coil wire with electrical contact that projects at coil carrier, where carrier with wire is held in yoke body, which is made of ferritic powder i.e. carbon powder, in defined grain size

摘要

The coil (3) has a coil wire (6) wound in multiple layers on a coil carrier (4), and an electrical contact of the coil wire projecting at the coil carrier. The coil carrier with the coil wire is held in a yoke body (1). The yoke body is made of ferritic powder (2) i.e. carbon powder, in a defined grain size. The yoke body is made by pressing the ferritic powder in a contour. Wall thickness of the yoke body is freely selected by a form press. The body exhibits magnetic characteristics influenced by the form press. The power is provided with polyadditive resin.
