ABSTRACT:
A quick-coupling joint for pipes comprises a female coupling element and a male coupling element, both of the elements being provided with spring-loaded shut-off valves for automatically terminating the flow of fluid through said coupling elements whenever they are disconnected, the valves being automatically shifted to their open positions when the coupling elements are connected. The spring for the valve of the male coupling element is a helical coil spring having axially spaced coil sections of two different diameters, such that the larger diameter section expands outwardly and firmly embraces axial ribs formed in the flow passage of the male element so as to anchor the spring, and the lesser diameter section biases and moves with the valve element. The male element valve is guided axially by the axial ribs, which form flow passages about the valve when in the open position.
