The drive unit comprises a transmission configured to convert the rotary motion with respective first and second periodically variable angular velocities (ω1, ω2) of said first and second rotor (4, 5), offset from each other, into a rotary motion at a constant angular velocity. The heat machine further comprises a compensation tank (44), configured to accumulate the compressed thermal fluid from the drive unit, a regenerator (42) configured to preheat the thermal fluid, a heater (41) configured to superheat the thermal fluid circulating in the serpentine coil, a burner (40), configured to supply the necessary thermal energy to the heater (41); wherein the regenerator (42), in fluid communication with the drive unit (1), is further configured to acquire energy-heat from the exhausted thermal fluid and use it to preheat the thermal fluid to be sent to the heater (41). The invention further relates to a method for realizing a heat cycle by means of said heat machine.

Abstract: The absolute novelty of the new combined SEOL cycle is represented by the recovery vapor Generator (GVR) which completely substitutes the Regenerator, of the prior art, being capable of recovering the energy differential (QR) between the temperature at the end of expansion and the temperature at nearly complete condensation of the thermal fluid and then, by using this great energy differential, it is capable of producing water vapor, entirely reusable in the preheating of the mixture, considerably contributing to the increase of the overall energy yield of the cycle and to the increase of the unit power of the heat engine. With the use of the new combined SEOL cycle, it is possible to obtain the following main advantages: A_ increase of the unit power of the heat engine, due to the increase of enthalpy of the mixture which is introduced in the Expander (ES); B_ considerable increase of the overall thermal yield, following the energy recovery (QR) that takes place in the recovery vapor Generator (GVR); C_ possibility of lubricating the cylinders and/or the sliding chambers of the pistons of the heat engine, with decrease of the mechanical friction and of the wear and consequent increase of the overall yield of the engine itself; D_ possibility of using multiple heat sources (QH), capable of heating to a sufficient temperature the mixture circulating in the Superheater (SR); E_ possibility of designing and industrializing new "heat engines" characterized by high overall yields and reduced production costs.
