ABSTRACT:
An apparatus for adjustably controlling the flow of air in an air conditioning system and comprising a regulator having flow control means movable in response to fluctuations in the pressure of the air supplied to the regulator for maintaining the flow of air passing through the regulator at a substantially constant rate and having flow adjustment means cooperating with the flow control means for permitting varying the flow rate maintained by the flow control means. In order to effect adjustment of the flow rate through the regulator, an actuator device is provided cooperating with the flow adjustment means and comprising a thermal motor having an axially movable shaft extending therefrom, a heater cooperating with the thermal motor for applying heat thereto to effect an axial movement to the motor shaft, and linkage cooperating with the motor shaft and operatively connecting the same to the flow adjustment means for effecting adjustment of the rate of flow through the regulator in response to the axial movement of the motor shaft.
