Abstract
A coupling device has two detachably connectable parts which are provided with two valves that are activated in the connected position of the parts. In said connected position, two separate channels are formed through the coupling device; the first channel transmits to a first medium and the second channel transmits to a second medium. The first channel extends through a unit positioned in the coupling device. The unit slidingly moves in the longitudinal direction of the coupling device during connection of the parts. The sliding movement of the unit is coordinated with the opening movement of the valve of the first part.
