A hot-gas machine in which a gaseous medium performs a closed thermodynamic cycle, includes a heat conveying device which is capable of conveying heat by means of an evaporation - condensation process from a heat source to the heater of the machine. This device comprises at least two closed spaces containing conveying-medium and arranged one after the other in the direction of heat conveyance, the distal ends of these spaces being provided with heat transferring walls across which heat can be conducted from the heat source to the conveying medium, or the conveying medium can give off heat to the heater; the proximal ends of these spaces comprises further heat-transferring walls, between which a switching element is provided for the establishment of a thermal and variable contact between these further walls.
