Abstract:
1. A free swinging piston heat machine, operating together with at least one oscillating rotary electrical machine, comprising: a housing with a cylindrical cavity; two piston assemblies placed in the cylindrical cavity, which each consist of a cylindrical hub and attached vanes arranged in a form of a symmetrical star, the piston assemblies being configured to pivot around an axis of the cylindrical cavity; and two rotors of the at least one oscillating rotary electrical machine, the rotors being arranged concentrically or coaxially with the piston assemblies, each rotor being coupled with corresponding piston assemblies, such that the rotors oscillate together with the piston assemblies, wherein the piston assemblies, oscillating around the axis of the cylindrical cavity in opposite directions, create working chambers of the heat machine between adjacent vanes of different piston assemblies, and wherein oscillation of free pistons is controlled via the at least one oscillating rotary electrical machine.
