Abstract
Abstract This disclosure is directed to a controlled volume air terminal outlet for use at a room discharge of an air distribution system for a building. The terminal outlet includes a first damper section which is thermostatically controlled for throttling air passing therethrough and a second damper section which is manually or otherwise controlled. Discharge through the terminal outlets passes through a diffuser for air pattern control. A pressure and temperature branch control is also disclosed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
242 words
A terminal outlet for use at a discharge location from a building air distribution duct system for delivering conditioned air into a room comprising: a unitary housing having elongate air passage therethrough and terminating at its rear in an outwardly turned annular flange for securing the housing to the side of an air duct surrounding an opening for air communication therethrough, pneumatic expansible oval casing means transversely disposed in one portion of the housing air passage for expansion and contraction in thermostatic response to the temperature is the room to which conditioned air is being delivered so as to control the volume of conditioned air delivered through said one portion to tHe room, manually adjustable damper means disposed in another portion of said housing for independently controlling the volume of air passing through said another portion for straight ahead projection into the room irresponsive to thermostatic conditions in the room, said damper means being manually adjustable by screw means accessible at the air discharge end of said another portion, plural banks of air turning vanes at the discharge side of said housing, one bank horizontally mounted within the housing and manually positionable for giving a vertical component on air movement independently selectively in front of either of said housing portions, another bank vertically mounted within the housing and manually positionable for giving a lateral component on air movement from only said one portion after having passed through said first mentioned one bank.
