Abstract
A fluid coupling wherein a tubular socket has a first terminal connectable with a first pipe and a section for reception of a section of a tubular plug further having a second terminal connectable with a second pipe. The axial passage of the socket contains a first normally closed valve, and the axial passage of the plug contains a second normally closed valve. The two valves open each other in automatic response to insertion of the plug section into the socket section, and each valve closes in automatic response to extraction of the plug section from the socket section. The seat of each of the two valves is a press fit in the respective passage.
