Description

The invention relates to heat engines, which can be used as drives for various mechanisms, where solar energy, heat of associated, flare gases of oil fields, natural gases and various industries can be used as a source.

Heat engines1 are known piston, rotor, jet, combined are possible, according to the method of heat supply - internal combustion and external combustion. All of them have low efficiency (ranging from 0.1 to 0.6), require expensive fuel with strictly defined parameters for operation; having a rather high rotational output, in many cases applications require rotary motion transducers with a high gear ratio

Known heat engine that uses the energy of the difference in temperature of the surrounding air and the water of the difference

temperatures of surface and deep water layers. It has a rotor on which temperature-sensitive elements are installed in the heating and cooling zones, which through a complex system (levers, ratchets, planetary gear, hydraulic system) convert linear movements into rotational motion of the rotor.

The insignificant temperature difference, which exists in this case, requires for tangible movements of the rotor of elements of a large length and, consequently, of a large engine size, a large metal consumption for a slight output power. In addition, there is instability depending on the ambient temperature, freezing of the rotor.

The purpose of the invention is to increase the torque and simplify the design.

This goal is achieved by the fact that heat energy is converted into mechanical energy of rotational motion due to linear expansion
