Abstract: This paper presents a creative study for volumetric efficiency improvement of rolling piston type compressor based on TRIZ theory. At first, the paper introduced the disadvantage of suction volumetric efficiency for existing rolling piston type compressor, then analyzed the problem with Little Man method of TRIZ creative theory, found out the means to overcome the problem, established mass-field analysis, and found out the standard resolution and related creative principle in order to solve the problem. Finally, we suggested a new technical design, and improved the suction volumetric efficiency of rolling piston type compressor.

Key words: Rolling piston type compressor, TRIZ creative principle, Little Man method, Mass-field analysis, Suction volumetric efficiency, Gas output
