ABSTRACT:
A thermal modulating control valve for providing bleed air for aircraft anti-icing purposes includes a valve chamber with an inlet for high temperature bleed air and an outlet for temperature modulated bleed air for aircraft systems. A modular valve mechanism is mounted in a chamber for regulating the flow of hot bleed air to the outlet in response to the temperature of the supply. The valve includes a first wall section having a plurality of spaced apart flow orifices or openings in one face and fixedly secured adjacent the inlet end of the chamber, and a second confronting wall section having a plurality of spaced apart flow orifices or openings provided to directly confront the orifices in the first wall section. The wall sections are movable relative to one another in response to the temperature of the bleed air at the inlet end so as to displace the respective sets of flow orifices in and out of registry for controlling the flow of bleed air supplied to the outlet of the valve. A solenoid controlled on/off poppet valve is provided to supply and shut off bleed air to the thermal modulating valve mechanism.
