Abstract
A thermal modulating control valve adapted for supplying thermal modulated bleed air for an aircraft anti-icing system comprises a valve body having an inlet adapted to be supplied with bleed air from a separate source and an anti-icing outlet for supplying thermal modulated bleed air for operating an aircraft anti-icing system. The thermal modulating valve is mounted in the body in communication with the inlet and outlet for supplying bleed air at a regulated flow rate which is reduced in response to increased temperature of the bleed air supplied to the valve. The thermal modulating valve includes at least one annular seating ring having a central bore and mounted on a support element, and the seating ring includes an annular ring sleeve spaced outwardly of the support element having at least one radial annular face concentrically mounted on the support element. At least one annular, bimetal, temperature sensitive creep disc is mounted on the support element having an outer edge portion deformable toward and away from the annular face of the ring sleeve in response to temperature changes for regulating the flow area between the disc and the ring sleeve for controlling the flow of bleed air to an anti-icing outlet in the valve body.
