<p>The coupling consists of two relatively sealed coupling sections, formed as a plug- and a socket valve. Each valve has a sealing element with closing springs. One coupling section has a stop to limit the stroke of the sealing element, in the opening position. The other coupling section has a stronger spring for the sealing element and executes a valve stroke, which is double the opening stroke of the other sealing element. The sealing element (3) having the larger opening stroke, when in the open position, has a surface charged by the pressure medium in the closing direction.</p> |
