Definitions

  • the electromagnetic actuator comprises in a manner known per se a coil 1 fixed around a tube made of non-magnetic material 2 in which a magnetic actuating member 3 is mounted to slide.
  • the coil 1 is connected by a supply wire 4 to supply means not shown making it possible to excite or de-excite the coil to operate the magnetic actuating member.
  • a ring 5 forming a permanent magnet, for example a ferrite ring whose permanent magnetization field extends in an axial direction of the ring, is arranged around the coil so as to extend opposite the central part of the external surface of the coil.
  • the field generated by the ring 5 thus extends in an axial direction of the coil 1.
  • the ring 5. is surrounded by two rings 6 made of magnetic material, for example mild steel.
