20160138746 | TWIST-TO-CONNECT DRY BREAK COUPLING - A coupling including female and male couplers configured to be coupled by first and second stage connections. In the first stage connection, a plurality of detents in the female coupler are urged into a detent recess in the male coupler to coupled the female and male couplers. To make the second stage connection after the first stage connection has been made, threads on the male coupler are mated with threads on a release sleeve, which causes valves disposed in the female and male couplers to move to an open position to allow fluid flow through the coupling. In this way, reduced force is employed to engage the female and male couplers while avoiding contact between the detents and the threads on the male coupler, thereby preventing the detents and threads on the male coupler from damaging one another. | 05-19-2016 |
