- the free end 80 of the respective stop bar 78 consequently strikes against the inside of the closure part 74 and catches the working piston 14, 16 moving in the direction of the respective closure part 74 in a damping manner.
- connection modules 62, 64 - or the sleeves 72 and the cover parts 64 - have on their respective radially outer side a circumferential groove with a sealing ring 68.
- the sealing rings 68 act sealingly against extending in the axial direction, radially inner cylindrical surfaces 82 of the housing 12.
- the cylindrical surfaces 82 together with the sleeves 72 and the cover parts 62 air ducts 84, which are connectable via terminals 86 with pressure lines, not shown.
- the pressure chambers 32, 34, 36, 38 can thus air along the arrow L from the terminals 86 via the air guide chambers 84, the respective recess 88 into the respective pressure chamber 32, 34, 36, 38 reach.
- a secure air flow is ensured regardless of the depth of engagement of the respective connection module 62, 64.
- the position of the housing-side terminals 86 is not changed at different depth of engagement.
- connection modules 92 are provided which have sleeves 72 extending in the axial direction that are relatively long.
- the pivoting angle of the pivoting part 20 can be varied within a substantial range.
- the connection modules 92 can limit the stroke of the working pistons 14, 16 more than the connection modules 64 according to the pivoting device 10 according to FIG Pivoting part 20 are changed in a relatively large area.
- the connection modules 62, 64 and 92 Auf- or Abschraubstoff in the form of a hexagon socket 94.
- FIG. 3 the view in the direction of the arrow III is shown on the swiveling device 10 according to FIG. 1 or the swiveling device 90 according to FIG.
- locking means 100 are shown, with which the connection modules 64 and 92 can be fixed in their axial position.
- the locking means 100 comprise a housing 12 held in the screw-like locking pin 102 with an eccentric head and a clamping member 106 which is penetrated by the locking pin 102.
- the eccentric head of the locking pin 102 is seated in a cylinder depression 104 of the clamping part 106.
- the clamping part 106 has two clamping surfaces 108 resting against the respective lateral surfaces of the connection modules 64, 92.
- For holding the locking pin 102 in the axial direction of the locking pin may have a radially encircling groove into which engages a transverse to the longitudinal axis of the locking pin 102 retaining pin so that the locking pin 102, although rotatably, but not slidably held in its axial direction.
- the swiveling device 110 shown in FIG. 4 has a housing 12 corresponding to the swiveling devices 10 and 90 with corresponding components which carry corresponding reference numbers to the swiveling devices 10, 90 according to FIGS. 1 and 2.
- 28 connecting modules 112 are provided in the pivoting device 10, in each of which a displaceable in two positions stop member 114 is provided, which is lockable in its axially inner position. This ensures that the working piston 14, 16 and thus the pivot member 20 can be approached in a predetermined intermediate position.
- the pressure side 42 facing stop member 114 is in this case in the locked intermediate position.
- connection modules 112 each have a housing 116 housed in a common auxiliary housing 113 in which the piston-like stop member 114 is mounted axially displaceable.
