At a device in a hydraulic machine of the type which comprises a runner or rotor with a hub body (1) and vanes or blades (4) which are rotatably journalled in bearings (7, 8) in the hub body, which has at least one chamber (2) which communicates with the said bearings, first means (20, 22, 23, 24, 25, 27, 28, 29) are provided for the supply of oil to said bearings and other means (18, 19, 37, 38, 39, 40, 41, 42) are provided for leading away oil from said chamber at pace with the supply of oil, such that the chamber is caused to contain an essentially constant volume (35, 35A) of oil, which is smaller than the total volume of the chamber, which oil volume is pressed towards the peripheral wall of the chamber by the centrifugal force at the rotation of the runner.
