FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to pneumatic motors powered by compressed air/gas. The system of the combined air motor 1 of a closed circuit with the supply of heat from natural sources includes an air motor 1 combined with a compressor, including a cylinder-piston group, as well as a cylinder head with a system of intake and exhaust manifolds 2 and 3 with a valve mechanism, as well as a compressor piston unit driven by assemblies air motor 1, including the inlet assembly 4 and the outlet assembly 5 of the working medium. The node 5 along the first circuit 7 of the pipeline passes through the main heat exchanger 8, heated by the third circuit 10 of the natural heat source, and is further connected to the collector 2 for transferring the working medium heated to the operating temperature. The collector 3 on the second circuit 9 of the pipeline is connected with the inlet 4. The pipeline on its way additionally passes through the air heat exchanger 6, where the working medium is cooled.
EFFECT: invention is aimed at improving the efficiency of the air motor, increasing its efficiency and torque.
