Abstract
Abstract Apparatus is disclosed for use in connection with an air distribution system, wherein air under pressure is supplied to an inlet to the apparatus and is distributed to either of two outlets. The first outlet is connected to a duct for delivery to a room, while the second outlet supplies air to the system return plenum. The air enters an air receiving chamber of the apparatus and is directed toward a wall positioned substantially transversely to the direction of air entering the chamber. The wall is rotatably mounted within the chamber and is positioned to rotate from a first position to a second position where the wall shrouds either the first inlet or the second inlet. Positioning of the wall between the first and second positions results in the proportioning of the air to the first and second outlets; the areas of the outlets are thus reduced in proportion to the reduction in the volume of air to be delivered through the inlet. The wall may comprise a perforated sheet having holes therein to admit audible pressure variations through the holes to a sound deadening chamber positioned immediately behind the wall. The volume thus delivered by the apparatus remains constant for any rotatable position of the wall.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
In an air distribution system, air distributing apparatus comprising: an air receiving chamber having an inlet, a first outlet, and a second outlet, each of said outlets having a predetermined effective area; means connecting said inlet to a source of conditioning air under pressure; a movable wall in said chamber positioned opposite said inlet and substantially transversely of air entering said chamber, said wall rotatably secured in said chamber and rotatable between a first position and a second position; said wall, when in said first position, closing said first outlet and opening said second outlet, and when in said second position closing said second outlet and opening said first outlet; said wall, when in positions intermediate said first and second positions, partially opening both said first and second outlets, the sum of the effective areas of the openings of said first and second outlets being equal to the effective area of one of said outlets, whereby the total volume of air per unit time being discharged through said apparatus remains constant; means connecting said first outlet to an air return for said air distribution system; and means connecting said second outlet to a duct for delivering air to a room.
Claim 2
Dependent Claim
200 words
In an air distribution system, air distributing apparatus comprising: an air receiving chamber having an inlet, a first outlet, and a second outlet, each of said outlets having a predetermined effective area; means connecting said inlet to a source of conditioning air under pressure; a movable wall in said chamber positioned opposite said inlet and substantially transversely of air entering said chamber, said wall rotatably secured in said chamber and rotatable between a first position and a second position; said wall, when in said first position, closing said first outlet and opening said second outlet, and when in said second position closing said second outlet and opening said first outlet; said wall, when in positions intermediate said first and second positions, partially opening both said first and second outlets, the sum of the effective areas of the openings of said first and second outlets being equal to the effective area of one of said outlets, whereby the total volume of air per unit time being discharged through said apparatus remains constant; means connecting said first outlet to an air return for said air distribution system; and means connecting said second outlet to a duct for delivering air to a room.
Claim 3
Dependent Claim
197 words
In an air distribution system, air distributing apparatus comprising: an air receiving chamber having an inlet, a first outlet, and a second outlet, each of said outlets having a predetermined area; means connecting said inlet to a source of conditioning air under pressure; a movable wall in said chamber positioned opposite said inlet and substantially transversely of air entering said chamber, said wall rotatably secured in said chamber and rotatable between a first position and a second position; said wall, when in said first position, closing said first outlet and opening said second outlet, and when in said second position closing said second outlet and opening said first outlet; said wall, when in positions intermediate said first and second positions, partially opening both said first and second outlets, the sum of the areas of the openings of said first and second outlets being equal to the area of one of said outlets, whereby the total volume of air per unit time being discharged through said apparatus remains constant; means connecting said first outlet to an air return for said air distribution system; and means connecting said second outlet to a duct for delivering air to a room.
Claim 4
Dependent Claim
197 words
In an air distribution system, air distributing apparatus comprising: an air receiving chamber having an inlet, a first outlet, and a second outlet, each of said outlets having a predetermined area; means connecting said inlet to a source of conditioning air under pressure; a movable wall in said chamber positioned opposite said inlet and substantially transversely of air entering said chamber, said wall rotatably secured in said chamber and rotatable between a first position and a second position; said wall, when in said first position, closing said first outlet and opening said second outlet, and when in said second position closing said second outlet and opening said first outlet; said wall, when in positions intermediate said first and second positions, partially opening both said first and second outlets, the sum of the areas of the openings of said first and second outlets being equal to the area of one of said outlets, whereby the total volume of air per unit time being discharged through said apparatus remains constant; means connecting said first outlet to an air return for said air distribution system; and means connecting said second outlet to a duct for delivering air to a room.
Claim 5
Dependent Claim
23 words
