Abstract
An apparatus for causing a portion of the compressed air from the compressor section of a gas turbine to bypass the combustor. The apparatus comprises a clamping ring and a rotating ring. The clamping ring joins the aft end of the combustor to the front end of a duct that directs the hot gas from the combustor to the turbine section. The rotating ring encircles the clamping ring. When the rotating ring is rotated into a first position, ports disposed in the rotating ring are aligned with ports in the clamping ring so that air can flow into the hot gas flowing between the combustor and the duct. However, the ports in the rotating ring are completely blocked by the clamping ring when the rotating ring is rotated into a second position and partially blocked when the rotating ring is rotated into intermediate positions. An actuating ring that encircles the combustion chamber controls the rotation of the rotating ring by means of an actuating rod that extends into the shell.
