  • 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.

  • 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.

  • 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.

  • Patent number: 4090161
    Abstract: In electromagnetic clutches or brakes in which the armature closes against the pole pieces of the coil without leaving an air gap, the faces of the poles or armature, or both, are broken up into smaller areas by annular grooves to reduce the lodgement and retention of contaminating and magnetically inhibiting particles resulting from wear.
