Abstract: A system includes at least one coalescer, a blow-by input module, and a boost air module. The at least one coalescer is configured to receive a blow-by mixture, to remove oil from the blow-by mixture to provide an oil drain supply, and to remove gas from the blow-by mixture to provide a gas vent supply. The coalescer is configured to receive an operational air supply. The blow-by input module is operably coupled to the at least one coalescer and configured to receive the blow-by mixture from a crankcase of an internal combustion engine and provide the blow-by mixture to the at least one coalescer. The boost air module is operably coupled to the at least one coalescer and configured to receive an air supply from an intake conduit of the internal combustion engine and to provide the air supply as the operational air supply to the at least one coalescer.

Abstract: A male coupling half includes a male valve and a male body and the female coupling half includes a female valve and an inner body. The inner body is slidingly movable with respect to a housing or manifold. The female coupling half further includes a valve seated against a dump valve body which relieves pressure in the female half of the coupling to enable easy connection of the coupling halves. The male and female valves are locked in their open positions when the coupling halves are fully connected and the female half is pressurized which prevents reverse flow checking in either flow direction. During the disconnection process the male valve is closed before the coupling halves are separated which traps pressure in the male coupling half.
