Disclosed herein is an apparatus for extracting thermal energy from thermal expansion of a working medium in the apparatus. The apparatus includes a thermal expander, a compressor for compressing the working medium after the expansion, and a force modulation unit connecting the thermal expander to the compressor. The force modulation unit consists of two conversion gears that are connected by a lever system. The lever system can be dynamically controlled so that the non-constant force from thermal expansion is modulated into a substantially constant output force of the apparatus. L'invention porte sur un appareil pour extraire de l'énergie thermique à partir d'une détente thermique d'un milieu de travail dans l'appareil. L'appareil comprend un détendeur thermique, un compresseur pour comprimer le milieu de travail après la détente, et une unité de modulation de force reliant le détendeur thermique au compresseur. L'unité de modulation de force est constituée par deux engrenages de conversion qui sont reliés par un système de levier. Le système de levier peut être commandé de façon dynamique de telle sorte que la force non constante à partir de la détente thermique est modulée en une force de sortie sensiblement constante de l'appareil.
