  • Solenoid
    Patent number: 8134439
    Abstract: A solenoid, in particular for switching pressure controllers or pressure valves, including an armature movable in an armature space, and a coil which can be impinged by current. When the coil is impinged by current, a magnetic field is generated serving for moving the armature, and the armature space can be filled with oil. For de-airing the armature space at least one de-airing channel is provided. In the de-airing channel at least one backflow-preventing element is provided which is permeable in the direction of de-airing.

  • Electromagnet
    Patent number: 6225886
    Abstract: The invention relates to an electromagnet, comprising a coil (30) which can be supplied with current and which thus generates a magnetic field and moves an armature (11) when supplied with current, and wherein the armature (11) serves for controlling a valve or another element. In order to improve the running properties of the armature (11), it is proposed that the armature (11) runs on a plastics sliding surface (2), in particular a sliding film (20) made of plastic.

  • Electromagnet
    Patent number: 6175291
    Abstract: A magnet coil which receives an armature movable longitudinally with respect to the coil axis and having an armature rod. A support of the armature or of the armature rod in a core serves also for the guidance of the magnetic field, a direct support of the armature or of the armature rod on a surface of the core.
