Abstract: A new mechanical model of scroll compressor composed of one crank and two sliders is developed. New model is agreeable not only to the principle of mechanism but also to the mechanism concept commonly accepted by the people. Mechanical and kinematic analysis of scroll compressor by using this model show that new model is a generalized one for scroll compressors of different configurations and reseals operation principle of scroll compressor as well as general pattern of operation regime. Especially, it provide theoretical basis for the key technique radial compliant mechanism in the design of scroll compressor.
