PURPOSE:To obtain the stable operation in all the operation region by installing a rib for suppressing the turning flow in a bleeding chamber onto a part in the bleeding chamber at the intermediate position in the peripheral direction of the exhaust pipes which are set continuous each other, thus preventing the unstable flow in the bleeding part. CONSTITUTION:Movable vanes 2 are arranged on the outer periphery of a rotor 1, and static vanes 4 are arranged on the inner periphery of a casing 3, a alternately. A bleeding port 5 is formed onto the outer wall of a flow passage between the static vanes 4, and a bleeding chamber 6 is formed on the outer periphery of the bleeding port 5, and a plurality of bleeding pipes 7 are installed onto the outer side of the bleeding chamber 6. In such constitution, a rib 12 for suppressing the turning flow in the bleeding chamber 6 is installed onto a part in the bleeding chamber 6 at the intermediate position in the circumferential direction of the contiguous exhaust pipes 7. Therefore, the stream which flows in and out from the bleeding chamber 6 is removed, and the stable flow in the bleeding part can be obtained, and the stable operation of the compressor in all the operation region can be obtained. |
