摘要：
A windage loss reduction system for a co-rotating scroll fluid device includes clearance reducing or optimizing elements mounted between rotating and fixed members of the scroll fluid device and which may be used individually or collectively to reduce centrifugal and axial fluid flow of ambient gases caused the rotating elements to improve the efficiency of the scroll fluid device. The windage loss reducing elements are located between fixed housing elements and the rotor, drive shaft, and scroll elements of the device.
