Abstract: A diversion valve fluid coupling, permitting alternate flows in first and second operating positions, including a valve housing with inlet, first and second outlet ports; a quick disconnect coupling attached to the second outlet port and a seal interposed therebetween; a movable diverter valve assembly, having interconnected actuating and opposing valves; the actuating valve, in the first operating position, having a first sealing engagement with the seal; the opposing valve, in the second operating position, having a second sealing engagement with a first outlet port; a biasing member, biasing the diverter valve into the first sealing engagement, blocking the second outlet port while permitting flow to the first outlet port; and, for the second operating position, a nipple member, removably mating with the quick disconnect coupling and translating the diverter valve into the second sealing engagement, blocking the first outlet port while permitting flow into the second outlet port.

Abstract: A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.
