Disclosed is an air volume regulator valve for an air distribution apparatus for heating, ventilating and air conditioning systems having a first open position, a closed position and a second open position and means for maintaining relatively constant volume of airflow under changing air inlet pressures. The valve may be cylindrical, flat or corrugated and has a “dead band”feature to allow the valve to better assist in controlling temperature of a room or plenum chamber to be heated or cooled.

An air regulating apparatus comprising a valve, said valve comprising a corrugated fixed sidewall having openings therein; a corrugated slidable sidewall having openings complementarily mounted on one side of said fixed corrugated sidewall to move in one direction relative to said fixed corrugated sidewall; said corrugated slidable sidewall being in communication with an air inlet; said corrugated fixed sidewall being in communication with an air outlet; said corrugated slidable sidewall being movable in a single direction from a first open position wherein said openings of said corrugated slidable sidewall are aligned with openings of said fixed corrugated sidewall to a closed position wherein the openings of said corrugated slidable sidewall are not aligned with the openings of said fixed corrugated sidewall and to a second open position wherein said openings of said corrugated slidable sidewall are aligned with openings of said fixed corrugated sidewall, means to move said first slidable sidewalls activated by temperature change, said fixed corrugated sidewall having means fixed thereto upon which said corrugated slidable sidewall is slidably mounted thereon.
