Abstract

See full text

In a scroll type compressor, the center and outer periphery portions of the spiral elements are provided with relief for preventing the mutual contact of the spiral elements. Both of the spiral elements come to contact with each other at the intermediate portion thereof. The relief at the center portion is formed within the range defined by the winding angle Y=32(X-1) where X is the winding turn of each of the spiral elements. The range of the intermediate portion is 380.degree.. This construction serves to prevent the excessive pressure increase of the operation chamber at the center portion so that the brake down of the spiral elements may be prevented without lowering the efficiency of the compressor.
