ABSTRACT:
A device for detachably coupling the orifice of a branchline to a conduit carrying a pressure medium having a plurality of discharge valves disposed spaced apart from each other along said conduit. Each of the valves has a discharge opening, and a closing element for each of said openings. A coupling device has the orifice disposed therein and is longitudinally displaceable along the conduit and connectable with the conduit by opening one of the discharge valves. The coupling device has a coupling element which is guided on the conduit and an automatically sealing coupling in the coupling position with the discharge valve at the pressure side for an automatic alignment with the orifice, and an actuator effective to actuate a respective one of the discharge valves in the coupling position of the coupling element.
