- connection module advantageously provides an external or internal thread for screwing onto the free end of the cylinder tube. It can be screwed onto the cylinder barrel in a simple manner and without expensive tools.
- connection module can be designed, for example, as a cover part for closing the free end of the cylinder tube. It is also conceivable that the connection module can be designed as a stop part for the axial stroke limitation of the working piston. The stop part can also include the function of a cover that closes the free end of the cylinder tube. It is also possible according to the invention that the connection module comprises damping means for damping the striking of the working piston. Such damping means can be, for example, cushions, cushions or the like provided on the inside of the connection module facing the working piston.
- connection module can be screwed onto the cylinder tube at different depths, the stroke of the working piston, and thus the angle of rotation of the swivel part, being variable via the screw-in depth of the connection module.
- fixing means are provided on the connection module and / or on the housing for fixing the connection module in a predeterminable axial position.

- the stop part 114 When the pressure chamber 118 is pressurized, the stop part 114 is moved into the intermediate position. For this purpose, the stop part 114 moves in the direction of the respective working piston 14, 16 until it strikes with its collar-like stop 132 against a stop 134 on the sleeve side. Due to the pressurization of the pressure chamber 118, a locking piston 120, which is axially displaceably mounted on the inside of the stop part 114, then moves in the direction of the associated working piston 14, 16 against the spring force of a compression spring 122 for locking balls 128 connect. In the starting position, the locking balls 128 lie partly in the receptacles 126, partly in receiving openings 129 provided on the stop part 114 and extending in the radial direction.

A plurality of locking balls 128, which are arranged at equal distances from one another, are preferably provided over the circumference of the stop part.
- the balls 128 When moving into the locking position, the balls 128 are positively guided radially outward from their receptacles 126 via the guide bevels 124 into locking receptacles 130 provided on the inside of the sleeve 116.
- the locking receptacles 130 extend approximately half a ball diameter in radial directions.
- the locking receptacles 130 can either be designed as individual receptacles or as a single circumferential, annular groove-like receptacle.
- the geometries of the receptacles 126, the locking balls 128, the receiving openings 129 and the locking receptacles 130 are such that, in the locked intermediate position of the respective working piston 14, 16 or the damping means 76, forces acting axially on the respective stop part 114 via the locking balls 128 into the sleeve 116 and from the sleeve via the screw connection of the sleeve to the housing 12 into the housing 12.
- the locked intermediate position is maintained as long as the pressure chamber 118 is pressurized. If the pressure chamber 118 is depressurized, the locking piston 120 is first displaced axially outward via the compression spring 122. As a result, the locking balls 128 fall into the receptacles 126 Moving the working piston 14, 16 against the stop part 114, the stop part 114 together with the locking piston 120 and locking balls 128 is carried axially outward until the stop part 114 has reached its starting position. The pivoting part 20 is pivoted into the starting position.
- connection modules 62, 64, 92 or 112 can be provided.
- the connection modules can be changed with little effort and can be done with simple tools.
