The invention relates to a hydrodynamic retarder device, comprising a rotor (20) and a stator (42) which together form a workspace (44) connected to a first fluid circuit (49), and a first expansion vessel (72) connected to the first fluid circuit (49). A second expansion vessel (73) is connected to the work- space (44), which second expansion vessel (73) is arranged to supply fluid (46) to the workspace (44). The invention also relates to a vehicle (1) comprising such a hydrodynamic retarder device (2). The invention also relates to a method of controlling a hydrodynamic retarder device (2).

    L'invention concerne un dispositif retardateur hydrodynamique, comprenant un rotor (20) et un stator (42) qui forment ensemble un espace de travail (44) relié à un premier circuit fluide (49), et un premier récipient d'expansion (72) relié au premier circuit fluide (49). Un second récipient d'expansion (73) est relié à l'espace de travail (44), ledit second récipient d'expansion (73) étant conçu pour amener le fluide (46) dans l'espace de travail (44). L'invention concerne également un véhicule (1) comprenant un tel dispositif retardateur hydrodynamique (2). L'invention concerne enfin un procédé de commande d'un dispositif retardateur hydrodynamique (2).
