FIELD: machine building.
SUBSTANCE: invention relates to the field of engineering and can be used as a power plant for vehicles, as well as for power drive machines and mechanisms. Pneumatic motor contains the working cylinders with inlet and outlet valves, a connecting rod and piston group, which is connected to the crankshaft. High-pressure cylinder is connected to the ejector through the control valve. And the ejector is connected to the working cylinder.
EFFECT: use of the ejector allows to increase the energy efficiency and to reduce the specific consumption of a working fluid per unit of produced power.
