Abstract
A compressor bleed valve of a gas turbine engine includes a valve support, and a valve element positioned at the valve support and movable relative to the valve support from an open position into a closed position engaged with a valve seat. The movement of the valve element toward the closed position is driven by a phase change of a volume of phase change material disposed in the valve support between the valve support and the valve element.
