Abstract:
A quick-action fluid coupling for fluid conducting lines, said coupling comprising:a generally cylindrical first member having an axial fluid flow passageway therethrough and a coupling end portion; a generally cylindrical second member having a coupling end portion that is engageable with said coupling end portion of said first member for coaxial coupled relation between said first and second members, said second member having a corresponding axial fluid flow passage therethrough so that when said coupling end portion of said second member is coupled with said coupling end portion of said first member, a single fluid flow passage is defined through said first and second member; means for releasably securing said first and second members in coaxial coupled relation for the flow of fluid therethrough; and a valve mounted in the fluid flow passageway of one of said first and second members and operable to close said fluid flow passageway when fluid pressure differential across the valve drops below a predetermined level, said valve comprising a valve body mounted on a valve stem axially secured in said coupling member by a valve guide, said valve body being mounted for axially slidable movement on said stem in response to fluid pressure.
