Definitions

  • the invention relates to an actuating device according to the type of the main claim.
  • a control device known from DE-OS 33 00 437 has the disadvantage that, in particular, proportional magnets emit different forces on the armature or plunger due to production variations and permeability differences under the same electrical conditions. With proportional valves, this leads to different pressures or flow rates.
  • the electronic control must be individually adapted to the associated valve, and if one of the two components, the valve control fails, the electronics must be readjusted or a complete exchange carried out in order to be able to maintain the specified setpoints.
  • the actuating device according to the invention with the characterizing features of the main claim has the advantage that the magnetic force can be varied by the described formation of the iron circuit.
  • By changing the magnetic resistance at constant magnetic flux, which is proportional to the coil current creates a unified assignment of magnetic force to the coil current. Due to the adjustability of the magnetic resistance, it can be adapted to the required setpoints without the electronic control having to be replaced or changed. If one of the two components - valve or control - fails, there is no need to completely replace or readjust the control electronics.
  • a magnet coil 16 is arranged in the bore 14, the outer diameter of which corresponds to the bore 14 and the inner diameter of which is smaller than the diameter of the bore 13.
  • the coil 16 is shorter than the bore 14.
  • the housing 11 is closed on the side opposite the end plate 10 by a magnetically conductive disk 18 which has an aligned bore 19 which corresponds to the inside diameter of the coil 16.
  • the disc 18 is fitted into the housing so that the coil 16 is fixed in its position.
  • the part of the pressure tube 20 protruding from the housing 11 has an external thread 21 for connection to a valve, not shown.
  • the pressure tube 20 is composed of three tube parts 23, 24, 25, of which the tube parts 23 and 25 are made of magnetic material and the tube part 24 is made of non-magnetic material.
  • An axial bore 27 is arranged in the pressure tube part 23 starting from the valve side and merges into an aligned bore 28 of larger diameter in the area of the disk 18.
  • the bore 28 continues in the tubular part 24 and merges into a continuous bore 29 of smaller diameter in the tubular part 25.
  • the end of the bore 29 facing the end plate 10 is designed as a threaded bore 29A.
  • a cylindrical armature 30 is guided with play, which extends via a plunger 32 projecting through the bore 27, for. B. actuated the valve spool of a directional valve.
  • the armature 30 has an axial blind bore 31 in its side facing away from the valve.
  • one end of a compression spring 33 is supported, the opposite end of which rests on an adjusting screw 35 located in the bore 29, 29A.
  • the adjusting screw 35 closes the bore 29 and thus the pressure pipe 20 in a pressure-tight manner with a sealing ring 37 located in an annular groove 36.
  • an adjusting sleeve 39 is arranged, the outer diameter of which is designed as a corresponding thread 39A.
  • the inner diameter of the sleeve 39 corresponds to the coil inner diameter or the pressure tube diameter.
  • the overlap "Ü" between the sleeve 39 and the pressure tube 20 and thus the magnetic resistance opposing the magnetic flux can be changed.
  • the degree of coverage determines the level of the magnetic contact resistance and thus the total resistance. If the coverage becomes zero or negative, strong stray fluxes occur and the magnetic force on the armature drops considerably.
