Abstract
A coupling device, having at least one coupling part which has an actuating device which actuates a closure part, wherein a flexible line part having a free cross section can be connected to the coupling part. The closure part, in its actuated position, opens up the free cross section of the line part and, in a further actuated position, closes said cross section, wherein the closure part has a flexible diaphragm.
Claims18
A coupling device, having at least one coupling element which comprises an actuating device that actuates a closure part, wherein
- a flexible conduit portion comprising a free cross-section can be connected to the coupling element;
- the closure part, in a first actuated position, releases the free cross-section of the conduit portion and closes this cross-section in a further actuated position;
- the closure part comprises a flexible membrane;
- and wherein
- the free cross-section of the conduit portion is cylindrical in the connection region with the coupling element in one actuating position and, in the other actuating position, using the actuating device, it assumes a closed shell shape, in which the wall portions of the conduit portion lie on top of another.

A coupling system having two coupling devices;
- wherein
- each coupling device has at least one coupling element, which comprises an actuating device that actuates a closure part;
- wherein
- a flexible conduit portion comprising a free cross-section can be connected to the coupling element;
- the closure part, in a first actuated position, releases the free cross-section of the conduit portion and closes this cross-section in a further actuated position;
- the closure part comprises a flexible membrane;
- and wherein
- the free cross-section of the conduit portion is cylindrical in the connection region with the coupling element in one actuating position and, in the other actuating position, using the actuating device, it assumes a closed shell shape, in which the wall portions of the conduit portion lie on top of another.
