Definitions

  • the present invention relates firstly to a magnet armature, at least comprising an arm ⁇ ture body made from magnetic or magnetizable material, which armature body comprises a passage with one open end, an assembly of sealing means being accommodated in the passage, which assembly of sealing means comprises at least one displaceable sealing element, spring means and a reinforcement component, the displaceable sealing element being held under prestress by the spring means, and with the intervention of the reinforcement component, against a stop in the passage, in the vicinity of the open end of the passage.

  • Magnet armatures of this nature, and in particular the components of the assembly of sealing means present therein have relatively small dimensions.
  • the sealing element can be displaced under prestress in the passage, so that when an armature of this nature is used to close a feed or discharge port in a shut-off valve, the closure force is determined not by the electromagnetic force but by the spring stress of the spring means.

  • the spring means used is a coil spring
  • the reinforcement component used is a metal sleeve which is pushed over the spring
  • the sealing element used is a small rubber disc. Then, the assembly is enclosed in the passage under stress from the spring. To enclose it, it is possible, for example, to flange over the end slightly, or to use rivets, or to add an annular cap.
  • the sealing element can be moved slightly into the passage counter to the prestress applied by the spring. This displacement therefore has a self-restoring character.
  • the object of the present invention is to provide a solution to the above problem, and, to that end, is characterized in that the assembly of sealing means is introduced into the passage as an assembly of sealing means which forms a single unit with components which are coupled together at least during assembly of the magnet armature.

  • suitable rubber-like materials for the sealing elements are thermoplastic materials, rubbers such as NBR, HNBR and FKM.
  • the components of the assembly of sealing means can easily be fitted during its production by snapping them together.
