Rotary piston gas compressor used in automobile field, has cylindrical housing with rotary piston comprising ring segments connected with outer contours so as to form pressure surface

摘要

The compressor has cylindrical housing (1-1) with a workspace in which rotary piston (1-2) comprising ring segments (1-21,1-21',1-22) is arranged in gastight state. The maximum outer radius of each ring segment is equal to the inner radius of the cylindrical housing. The minimum outer radius of each ring segment is smaller than the inner radius of the cylindrical housing. A pressure surface is formed by connecting the ring segments and outer contours (1-23,1-24).
