FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to a system of a combined closed circuit pneumatic motor with an external heat source. The system 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 an air compressor piston unit driven by the air motor 1 assemblies, including an inlet assembly 4 and a 5 release of the working environment. Unit 5 is connected via the first circuit of the pipeline to the combustion chamber 8 of an external heat source, including a tank 10 with a secondary coolant, an external energy source 11. The outlet pipe 12 of the chamber 8 is connected via a pipeline to the manifold 2 of the air motor 1 for transferring the working medium heated to the operating temperature. The collector 3 is connected to the assembly 4 along the second circuit of the pipeline. The pipeline on its way 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.
