A power control device for a hot gas engine comprises continuously communicating connections between each working gas charge undergoing cyclic pressure variations and a conduit network containing gas at mean pressure. The connections are provided with capillary tubes allowing passage of low-rate flows of gas but preventing transmission of rapid pressure fluctuations. The conduit network is connected through control valves to a gas reservoir and gas compressor, which enable the mean pressure to be increased or decreased.
