ABSTRACT:
A combination quick disconnect coupling and liquid cutoff valve comprises a first tubular member, and a second tubular member having a cylindrical sheath slidably disposed about and extending therefrom, sized for telescopic insertion into the first tubular member. The first and second tubular members may be coupled together and retained in that position as required. Two fluid passageways extend through the second tubular member. A third tubular member is concentrically positioned within the second tubular member and has a resilient, releasable, penetrable diaphragm at one end. A piercing pin is disposed within the movable cylindrical sheath so that when the piercing pin is exterior to the diaphragm, a first liquid passes through the connector, but when the piercing pin is inserted through the penetrable diaphragm, a second liquid passes through the connector and the flow of the first liquid is shut off.
