- the plug-in mounting direction 55 illustrated by arrows in the drawing extends, seen in the operating position of the space divider and stop unit 38, in particular in a plane perpendicular to the central axis 5 and preferably radially with respect to the central axis 5.
- the elements 24, 42 preferably in one to the main circumferential direction 34 transversely and in particular re right-angled oriented direction plugged together and, if necessary, again detachable from each other.
- the first mounting interface 45a formed on the room divider element 24 can form a plug connection device 54 together with a first fastening interface 48a of an arbitrary stop element 42.
- the second mounting interface 45b arranged on the room divider element 24 can likewise form a plug connection device 54 with the first fastening interface 48a of each stop element 42.
- the first attachment interface 48a of any stop element 42 with the second attachment interface 48b of any further stop element 42 also a
- the mutually complementary latching connection means 46a, 46b, 49a, 49b are expediently designed hook-shaped, which is particularly apparent from Figures 4, 8, 12 and 14 well.
- the hook-shaped structured latching connection means 46a, 46b of the two mounting interfaces 45a, 45b define a plug-in recess 55.
- the insertion recesses 55 are in particular to the radial outside of the central axis 5 opposite
- the hook-shaped latching connection means 49a of the first attachment interface 48a formed on each stop means 42 preferably have the shape of laterally projecting, essentially L-shaped arms whose width is matched to the width of the insertion recesses 55 is that they can be inserted into these Einsteckausnaturalisme 55.
- Room divider element 24 or stop element 42 is inserted or inserted until the latching connection means 49a engage or snap into the other latching connection means 46a, 46b, 49b and thereby a preferably easily detachable element composite is produced.
- the room divider and stop unit 38 is a self-supporting, inherently rigid one Structure forms, which can be easily inserted by means of mechanical handling devices in the working space 3.
- the stop elements 42 are preferably one-piece components, which consist of a plastic material.
- the same plastic material is preferably used in the production of the main body 28 of the room divider element 24.
- As the drive fluid for the fluid-operated rotary drive device 1 in particular compressed air is provided, although for any other gaseous medium or liquid media are suitable.
