<p>AIR REGISTER WITH AUTOMATIC ZONE CONTROL An air register for distributing air to a room has a thermally responsive actuator element in direct contact with a pivotably mounted closure slat for controlling the flow of air through the register. The air is distributed upwardly along the wall of a room and a venturi, mounted in the air flow path, draws air in through an opening in the front of the register and over the actuator so that the actuator senses room temperature of the treated air passing through the register. The slats which control the flow of air through the register are biased in an open position and the actuator tends to close the slats through a direct linear force on the slats.</p> |
