The present article is a study on flow analysis for compressor as an air producing apparatus for air lumber support applied to automobile seat. The compressor type for application is a swash plate pump where 4 EA of plungers are operated sequentially. After modeling of the product, working pressure for each part, flow direction, flow velocity, flux of fluid are derived for analysis. For this purpose, analysis is made by using Analysis finite element analysis program after 3D modeling of swash

... ate compressor used for air bag type of lumber support with CATIA V5 R18 program. Processes where 4 pumps are sequentially operated during 1 stroke, and flow velocity and pressure of air at that time are obtained from the piston for analysis. Based on this result, major design factor variables are derived to allow application upon design.
