  • the arrangement of the adjusting rings is very stable overall and advantageously enables miniaturized designs of fluid-operated rotary drives. By setting the settings made via the setting rings, it is prevented that there are still minor changes in position set that can lead to inaccuracies in the position detection.

  • the lower adjustment ring is first rotated.
  • the setting made is then fixed by means of the further locking element assigned to the further setting slot.

  • the two setting rings 38, 39 can be releasably fixed to the housing.
  • each setting ring 38, 39 has an axially continuous arc-shaped setting slot 53, 54, the center of curvature of which lies in the ring center and thus on the pivot axis 34. They have an identical curvature and are arranged radially at the same distance from the pivot axis 34. For example, they also have the same longitudinal extent in the longitudinal direction of the slot.
  • the adjustment slots 53, 54 are arranged so that they overlap at least partially in the longitudinal direction of the slot.

  • the desired detection positions can be set very precisely without the risk of canting.
  • dot-dash lines at 32 ' indicate that the relative position between the actuating element, which is always maintained during operation 32 and the output shaft 13 can also vary if necessary.
