METHOD OF MUTUAL CONVERSION OF MECHANICAL ENERGY AND POTENTIAL ENERGY OF COMPRESSED GAS Russian patent published in 2014 - IPC F04B53/02 F04B39/00 F02B57/00 

FIELD: machine building.

SUBSTANCE: method of mutual conversion of mechanical energy and potential energy of compressed gas consists in cyclic change of gas volume in above-piston and/or below-piston cavity at reciprocating motion of a piston inside a cylinder. Gas in the said cavity is periodically renewed through gas supply and withdrawal channels. The cylinder and/or the piston are rotated around the axis parallel to the direction of the piston's reciprocating motion. The piston is installed in the cylinder with a minimum radial gap. The cylinder is partially filled by fluid. The action of centrifugal forces provides for the formation of free surface of the fluid. Difference of static fluid pressures in the above-piston and below-piston cavities, provided by the difference of radiuses of the fluid free surface, compensates the gas pressure difference in these cavities.

EFFECT: higher efficiency factor of the process due to reduced losses by friction and approximation of the compression process to the isothermal process.
