Abstract
A leak-resistant fluid coupling arrangement includes two coupling assemblies, each having valves for preventing fluid flow in a disconnected state, and for permitting fluid flow in a connected state. The valve in one of the assemblies is mounted within a tubular body having an external stop. A sleeve is mounted exteriorly of the tubular body. A spring bears against the sleeve and the stop to resiliently position a front surface of the tubular body adjacent an end wall of the valve. In the other assembly, the valve is located between a tubular part and a second tubular body, and has a seal that engages an internal shoulder of the second body. Apertures extend through the seal. A spring resiliently positions an end wall of the tubular part adjacent a front region of the second body. In the connected state, the seal is disengaged from the shoulder, and fluid flows through the apertures.
