Abstract: A quick connect/disconnect coupling having a female coupler and a corresponding male coupler. The female coupler has a non-spill configuration and includes a housing and a valve body slidably movable in the housing. A valve member is slidably movable in the valve body toward and away from a valve seat, the valve member being configured to engage the male coupler. A piston is interposed between a main cavity and a trap chamber of the female coupler. The piston may be fixed to the valve member for common movement, and may include an internal flow passage for enabling fluid connection between the main cavity and trap chamber. A check valve may allow fluid flow from the trap chamber to the main cavity when the trap chamber pressure is greater than the main cavity pressure. A locking collar may be independently movable of the valve body to reduce the force required to connect the couplers.

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.
