Definitions

  • the invention relates to a device for adjusting the actuating plunger of an actuator device with a working actuator, which acts on an actuator with a plunger.
  • Such actuator devices are used, for example, to actuate electrical or mechanical valves.
  • the ram position can change, for example due to material aging. So that the plunger can perform its function precisely, it is necessary to correct or readjust its position relative to an actuator over time.
  • the object is achieved in that the work actuator is guided together with the plunger along the actuating line of the plunger, that at the end of the plunger remote from the actuator, this interacts with an adjusting stop and that the plunger, which acts on the actuator during the action is immovably fixed in the work process by means of a locking actuator on the side of the work actuator remote from the actuator, while reset time intervals are released by the locking actuator for longitudinal displacement.
  • the plunger can then be readjusted by first moving fully to the actuator after the locking actuator has been released with the aid of the readjusting stop. Then the locking actuator is put back into operation and the plunger is locked in the newly set operating position.
  • the adjusting stop consists of a counter bearing and a compression spring arranged between the counter bearing and the tappet.
  • the compression spring presses the plunger against the actuator while the locking actuator is released.
  • the counter bearing consists of a wedge which pushes transversely to the tappet axis against the tappet end remote from the actuator. While the locking actuator is released, the wedge can then slide behind the plunger and push it forward to the actuator. The locking actuator then operates again.
  • all actuators consist of a stack of piezoelectric disks.
  • a plunger 1 is mounted displaceably in bearings 2 along a line 3.
  • This tappet can be a valve tappet or the like, which works on a schematically indicated actuator 5, for example a valve.
  • actuator 5 for example a valve.
  • a work actuator 11 which, for example, consists of piezoelectric disks stacked on top of one another in the direction of line 3.
  • the plunger 1 is supported on its end 13 remote from the actuator 5 by means of a compression spring 15 on a stationary abutment 16.
  • a locking actuator 17 also acts on the plunger 1.
  • the locking actuator is provided for this purpose with a plunger 19, which can be placed transversely to the longitudinal direction of the plunger 1 and the plunger in this case against a thrust bearing 21 presses.
  • the locking actuator 17 can also be constructed from piezoelectric disks. But it is also possible to easily design it as an electromagnet.
  • Fig. 2 only the left part of the overall device according to Fig. 1 is shown.
  • the compression spring 15 and the counter-bearing 16 according to FIG. 1 are replaced by an adjusting stamp 25 of an adjusting actuator 27.
  • the adjusting actuator 27 turns on the voltage U 27 is applied , and the adjusting punch 25 pushes transversely to the plunger 1 with an oblique wedge surface 29 against a corresponding one Adjustment surface 13 'of the plunger 1.
  • the locking actuator 17 is excited again, the plunger 19 fixes the plunger 1, and the adjustment actuator 27 is de-energized. However, he can also remain excited to maintain a counterpart.
  • the plunger 1 is also possible to design the plunger 1 to be resilient between the plunger 19 and the readjusting plunger 25.
