Abstract
A bleed valve for use in a gas turbine engine of an aircraft includes a high-pressure cavity coupled to a valve terminal, which is itself coupled to a cap, which cap includes a valve seat configured to be sealed by a tube that serves as the valve gate. The tube is operably coupled to a movable end of a bellows, which is positioned within the high-pressure cavity. The opening and closing of the valve is controlled by the movement of the bellows within the high-pressure cavity, and, in turn, the movement of the tube towards the valve seat, with the valve closing as the bellows compresses.
