[i]The two inlet gas connectors and the two outlet gas connectors are each interconnected by plenum chambers. [b]The ventilation ducts to the torso area[/b] and the head are connected to the inlet connectors.[/i]
[i]The inlet connector permits the distribution of inlet ventilating gas flow to the helmet, [b]torso ducts[/b], and to the adjacent inlet connect (EV configuration only). The inlet connector has a butterfly diverter valve with two positional modes; OPEN , used for intravehicular operations, and CLOSE, used for extravehicular operations. The position of the valve is identified by a raised projection on the diverter valve knob, horizontal for OPEN, and vertical for CLOSE. In the CLOSE (EV) position, the inlet gas flow is directed to the helmet vent duct and in the OPEN (IV) position, [b]the flow is divided between the helmet vent duct and the torso duct(s)[/b].[/i]
[i]Incoming gas is also supplied from one of the inlet connectors to the torso channels 380 and 382. [b]These channels preferably are pervious to gas along their length so that the gas is distributed to the astronauts torso over substantially the entire length of both the torso channels to which the gas is supplied.[/b][/i]
