Air Flow Control Damper With Linear Performance Characteristics Comprising An Air Foil Control Blade And Inner Annular Orifice
Air Flow Control Damper With Linear Performance Characteristics Comprising An Air Foil Control Blade And Inner Annular Orifice
US Patent:
2010017, Jul 15, 2010
Filed:
Jan 15, 2009
Appl. No.:
12/319948
Inventors:
Charles W. Coward - Moorestown NJ, US
International Classification:
F24F 13/10
US Classification:
454333
Abstract:
An air flow control damper consisting of either a tubular or rectangular casing, an internal annular orifice and within the orifice a rotatable circular or rectangular blade with an air foil profile. The blade may be either single or multi-part. The air flow control blade is designed to rotate on a shaft from an open position to a closed position modulating the air flowing through the casing. This damper exhibits a very low pressure drop—important for energy conservation—and a linear hystersis free performance curve—important when maintaining pressures in critical spaces.

International Classification:
F24F 7/00
US Classification:
454358
Abstract:
An air flow control device consisting of air foil designed vanes for accurate modulation of the air into and out of a space. This damper includes end seals in which the ends of the air foil control vanes are located. Upon closure of the vanes the end seals prevent the air from bypassing the vanes and a very tight close off is realized.
