<p>1. A hose system coupling, the housing thereof comprising a conical valve seat at each of the coupling members, the valve seat co-operating with a sealing element with a conical sealing surface, the sealing element comprising a radially extending front surface and being biased against the valve seat by means of a spring, the two sealing elements further comprising a slidingly supported rod each, wherein a first rod is supported in a bore of the first sealing element and is adapted to be abutted with the front surface of the second sealing element through an aperture in the front surface of the first sealing element, and the second rod is guided in a guiding portion in the coupling housing and serves as a guide for the second sealing element and wherein further an actuating device for the first rod is provided to adjust the first rod in direction of the second sealing element and the first sealing element and the second sealing element in the opening position and wherein finally a coupling connection is provided detachably connecting the coupling members, characterized in that the coupling housings (12, 13) comprise smooth radially extending front surfaces (20, 21) and are connectable by means of a U-shaped annular segment arrangement (54) co-operating with an outer annular groove (57) or an annular shoulder of the coupling housing (13), respectively, the radially extending front surfaces of the sealing elements (24, 25) approximately extend in the plane of the front surfaces (20, 21) of the housing in the closing position, and the first rod (28) is coupled with a gear unit (39) in the coupling housing (12) such that during the adjustment thereof in direction of the second sealing element (25) for the opening thereof also the first sealing element (24) is moved into the opening position.</p> |
