FIELD: machine building.
SUBSTANCE: method of gases gradual compression by group of free piston with pistons opposite movement compressors with pistons drive by gases energy from outside combustion chamber of double cylinder free piston with pistons opposite movement power module comprising the outside combustion chamber, power module pistons and connected with them compressor pistons, the combustion products entering from the outside combustion chamber of the power module in cavities of the power module pistons ensure oscillating movement of the power module pistons and of the connected with them compressor pistons, gas is compressed by the compressor pistons of the first compression stage, and compressed gas is supplied for suction and further compression by compressor of the second gas compression stage that differs from the compressor of the first compression stage by lesser area of the compressor pistons, from here it is similarly supplied for suction and compression by the compressor of the nest gas compression stage, which pistons area is lesser then pistons area of the previous compressor.
EFFECT: higher specific efficiency.
