Prilutski I.K., Arsenyev I.A., Molodov M.A., Priluzkii A. A., Shevtsova A.I.

Information about preliminary design of piston expander working on typical opposite base forced by shaft speed is quoted. Expander design is provided with original system of gas distribution, based on usage of normally open automatic valves allowing possibility of efficient expander work in wide range of performance parameters. Core of this research is theoretical-design analysis and construction optimization of low pressure gas piston expander, aimed for compressed nature gas energy utilization units as ecologically clean source of cold and electric power.
