The invention relates to a rotary sliding vane machine (1) for fluid processing, comprising a housing (2) with a cavity (4) with a rotor (9). Vanes (12) are arranged in outwardly directed slots (13) in the rotor (9), and relative sliding between the vanes and the rotor provides spaces with variable volumes in the rotational direction. Each vane is supported by hydrostatic slide bearings (20, 20′) on each side of the vane (12). Due to pressure changes of the process fluid, the vane (12) is tilted towards and away from bearing pads (27, 27, 87).
