Abstract
An improved thermally actuated diffuser is disclosed. The diffuser comprises four thermal sensor actuators. A first thermal sensor actuator is responsive to changes in the room air temperature when cool air is supplied through the duct into the room. A second thermal sensor actuator is responsive to the duct air and is adapted to engage the first thermal sensor actuator when cool air is supplied through the duct and to disengage the first thermal sensor actuator when warm air is supplied through the duct. A third thermal sensor actuator is responsive to changes in the room when warm air is supplied through the duct. A fourth thermal sensor actuator is responsive to changes in the duct air temperature and brings the third thermal sensor actuator into engagement when warm air is supplied through the duct and to disengage the third thermal sensor actuator when cool air is supplied through the duct.
