THERMAL ENERGY CONVERSION SYSTEM Russian patent published in 2023 - IPC F01K27/00 

FIELD: thermal energy.

SUBSTANCE: external combustion engines that convert thermal energy from an external source into another type of energy with the performance of useful work. The circuit sequentially includes a volumetric compressor, a heater made in the form of an externally heated container, and an expander for performing work. The compressor is made in the form of two containers, completely or partially filled with liquid; the compressor containers are connected by upper and lower communication lines, which are connected to the compressor cooling device. A hydraulic pump is installed on the lower communication line of the compressor tanks, connected through hydraulic distributors to the inlet of the compressor cooling device, the output of this cooling device is connected through the hydraulic distributor to the upper communication line of the compressor tanks. The ends of this line are connected to liquid diffusers located inside the compressor tanks in their upper parts. The closed circuit in the area between the compressor and the expander is made with a branching into two lines, each of which has its own heater with an external heat supply connected to the expander. The expander is made in the form of two containers, partially filled with liquid, on the communication line of which a hydraulic motor is installed. Check valves are installed on the communication lines between the heaters and the compressor and expander.

EFFECT: expansion of the scope of technical means, simplification of the process of converting thermal energy into mechanical energy, structural simplification of the system occurs due to the fact that in a closed loop with two components inside, one component is gas, and the second component is liquid, the working fluid in a closed loop is gas, and the liquid is used as pistons in the compressor and expander.
