ABSTRACT:
A circumferential manifold placed around an intermediate stage of the compressor to carry off bleed air for auxiliary purposes is provided with a plurality of check valves which allow the air to pass from the high pressure compartment of the compressor to the low pressure compartment of a plenum, but do not allow the air to pass from the plenum back to the manifold. Accordingly, when there is a variation in pressure around the circumferential manifold, as may be caused by distortion at the compressor inlet, the air that is bled off to the low pressure plenum comes principally from the high pressure zone of the compressor and may not re-enter from the manifold on the low pressure side thereof. The fluid flow of air from one side of the manifold to the other side thereof is thus prevented, so as to limit the distortion of the normal flow pattern which would otherwise occur in the compressor.
