ABSTRACT:
A coupling for connecting sections of flexible hose so that quick and safe emergency disconnection can be automatically effected. The coupling includes a female section carrying peripheral cam lever pins adjacent radial openings through the wall of the female section, and a male section sealingly engageable with the female section. The male section carries a peripheral cam groove positioned for alignment with the cam pins when the sections are joined. Each of the sections carries a valve subassembly which normally closes the open end of the respective section, but which is automatically repositioned to open the respective section when the sections are coupled. A quick disconnect latching subassembly is carried on the male section and includes cam levers cooperatively engageable with the lever pins and cam groove to cam the male section into coupling engagement with the female section, and a releasing linkage axially movable on the male section and connected to the cam levers to release the cam levers from the cam lever pins and cam groove upon undergoing such axial movement.
