The invention relates to a hydrodynamic machine, particularly a hydrodynamic retarder (1), comprising a retarder housing (2), a rotor (16) and a stator (17), wherein rotor (16) and stator (17) together form a working chamber (24), which can be filled with a working medium (15) according to the operational state of the machine, wherein the rotor (16) is arranged on a rotatably mounted shaft (3) mounted at least at one end on a bearing (18) inside the retarder housing (2), further comprising an idling pump (25), by means of which the working medium (15) can be pumped through a connecting duct (19) from a working medium reservoir (23) into the working chamber (24). To improve operating reliability in non-braking operation, it is proposed that the connecting duct is formed at least in part by the bearing (18), so that the bearing (18) is at least partially cooled and/or lubricated by the working medium (15) delivered by the idling pump (25).
