摘要： A scroll for use in conjunction with a fluid compressor is described. The scroll comprises a fluid inlet adapted to receive a fluid flow and a fluid outlet adapted to discharge the fluid flow. The scroll further comprises a scroll-shaped wall defining an inner flow volume. At least one blade is provided in the inner flow volume of the scroll. The blade is configured and arranged for correcting a direction of the flow of fluid in the flow volume when the scroll is operating in off-design conditions.
