Summary:The turbine according to the invention comprises a fixed volute (7F) and a mobile volute (7M) having spiraloid walls imbricated in one another, the mobile volute being able to achieve an orbital rotary movement relative to a central axis (AA) of the fixed volute, and a fluid chamber (7V) formed by a volume available between the spiroidal walls of the fixed and mobile volutes. According to the invention, the turbine comprises a thermostatically actuated volume variator (72) able to modify a working volume of the fluid chamber by axially moving (d) a chamber-volume-reducing heated sole (720) which is housed between the spiroidal walls of the fixed and mobile volutes. La turbine selon l'invention comprend une volute fixe (7F) et une volute mobile (7M) ayant des parois spiroïdales imbriquées l'une dans l'autre, la volute mobile étant apte à accomplir un mouvement rotatif orbital relativement à un axe central (AA) de la volute fixe, et une chambre de fluide (7V) formée par un volume disponible entre les parois spiroïdales des volutes fixe et mobile. Conformément à l'invention, la turbine comprend un variateur de volume à actionnement thermostatique (72) apte à modifier un volume utile de la chambre de fluide par un déplacement axial (d) d'une semelle chauffante de réduction de volume de chambre (720) qui est logée entre les parois spiroïdales des volutes fixe et mobile.
