  • Patent number: 4424827
    Abstract: A device for detachably coupling the orifice of a branchline to a line carrying a pressure medium and having a plurality of discharge valves spaced apart from each other in the line wall, the coupling being carried out by means of a coupling device which is movable over the length of the line and contains the orifice and opens one of the discharge valves. The discharge valves are mounted in the line with magnetically actuating opening members and the coupling device is provided with a coupling element guided thereon and is provided with an automatically sealing coupling member in the coupling position with the discharge valve at the pressure side for an automatic alignment with the orifice, and an actuator which magnetically cooperates with the opening member and the coupling member.
    Type: Grant
    Filed: September 2, 1981
    Date of Patent: January 10, 1984
    Assignee: Bachofen AG

  • Patent number: 4375822
    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.
