Definitions

  • the invention relates to a multi-stroke Steli cylinder using two interacting, pneumatically or hydraulically operated cylinders, such as those used to control switching elements of control units, for example. Measuring devices, transport devices and the like. Find us.
  • actuating cylinders of this type two cylinders are flanged to one another on the end faces, so that, in the case of cylinders of the same length, three positions of a switching element can optionally be actuated by actuating the two pistons.
  • Control device an abutment for the one piston rod, requires adequate support and safe guidance of one of the two cylinders.
  • the invention is therefore based on the object of avoiding these disadvantages by means of a simpler design and of ensuring greater operational reliability and freedom from maintenance with a lower weight of the device.
  • an exemplary embodiment of the invention is shown in a schematic manner in a Intermediate position shown inner cylinder.
  • the device consists of the outer cylinder 1 and the inner cylinder 2, which is displaceable therein and acts as a piston.
  • the outer cylinder 1 has an end closure by means of an end plate 11 screwed into the wall of the outer cylinder or otherwise connected in an airtight manner thereto.
  • four bores 12, 13, 14, 15 are provided for pressurizing the displacement with a pressure medium, of which the two outer bores 12 and 15 are close to the end plate 11 or the opposite end wall 17 are arranged.
  • the two middle bores 13 and 14 are arranged so that the piston 3 of the inner cylinder 2 can be pressurized with the pressure medium via bores 23 and 24 provided in the wall of the inner cylinder. These two bores 23 and 24 are arranged at the ends of the displacement of the inner cylinder 2 in the immediate vicinity of the end plate 21 inserted into the wall of the inner cylinder or the end wall 22 opposite this end plate.
  • a longitudinal recess 25 is provided on the circumference of the inner cylinder 2, via which the bore 14 of the outer cylinder 1 can be connected to the bore 24 of the inner cylinder 2.
  • the end plate 21 is inserted airtight in the wall of the inner cylinder 2 and is pressed by means of a retaining ring having an external thread against an annular shoulder provided on the inner wall of the inner cylinder 2. To seal the individual rooms or channels are used in the outer circumference of the inner cylinder 2, the piston 3 and the end plate 21 in annular grooves
  • the end plate 21 has an axia bore for the passage of the piston rod 4 and a sealing ring resting against it.
  • the piston rod 4 is further guided in an axial bore of the end wall of the outer cylinder 1, in which also a Piston rod 4 enclosing sealing ring is used and which has an externally threaded pin 16, by means of which the distance of the outer cylinder 1 from the position to be controlled by means of the piston rod 4 is fixed.
