Definitions

  • the production is particularly simple and inexpensive, if the Magnetic housing is a one-piece F technicallypreßteil that at its the actuation side opposite bottom part one inward, to the outside the magnet housing has open pole tube as a rear pole body.
  • O-ring 37 could be used as a sealing element also a seal arrangement of another kind, for example a gap seal or a coating with a sealant may be provided.
  • the magnetic piston 19 is for pressure equalization through an inner axial bore 47 crossed. Between armature piston 19 and the end facing the Polkernes 31 is a Antiklebscale 49 usual type.
  • the actuating pin 29 lies with its end face on the valve piston 51 of the actuated Directional valve 2 on.
  • the valve piston 51 is connected by a compression spring 53 to System biased on the actuating pin 29.
