摘要

The quick coupler for pipes comprises plug (2) and socket components containing spring-biased valves which open automatically when the components are connected. The valve body (11) carries a sealing ring (12) whose outer diameter in the closed position is greater than that of the bore (19) leading from the valve seat (22) to the position where the other component is fitted. The diameter of the section of the valve body which carries the sealing ring is such that it can move through the bore and the sealing ring is sufficiently flexible to allow it and the valve body to fit inside the component (2).
