STEAM MACHINE OF DOUBLE ACTION WITH COMBINED FREE PISTON Russian patent published in 2017 - IPC F01B31/26 F01B17/04 F01B11/08 

FIELD: mechanical engineering.

SUBSTANCE: steam machine contains filled with working fluid vertical cylinders, heaters/evaporators located in the upper parts of the cylinders, coolers/condensers, placed in the bottom of the cylinders, and pistons. Contains two similar steam machines, the internal cavities of the cylinder of which are located below the level of the refrigerators/capacitors and are directly connected to the opposite ends of one common to both machines cylinder of magnetic latches. The cylinder presents a horizontally disposed tube, which at both ends has bushings made of ferromagnetic material. There is a piston inside the sleeve, on both ends of which the magnets are placed. The piston can move freely along the tube axis from one end to the other so that the magnets on both ends of the piston are in contact with the respective sleeves. The internal cavities of cylinders of each machine are filled with a working medium so that the piston in the position of contact of the magnetic latch and one end of the cylinder latch magnetic working fluid of the steam engine, connected to this end, is in contact with the heater/evaporator. The working fluid of the steam machine, connected to the opposite end, is in contact with a refrigerator/condenser of associated steam machine.

EFFECT: construction simplifies to the limit.
