Title:
A ROTARY SLIDING VANE MACHINE WITH HYDROSTATIC SLIDE BEARINGS FOR THE VANES
Document Type and Number:
WIPO Patent Application WO/2019/139484
Kind Code:
A1
Abstract:
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). The invention causes the bearing pads to adjust their position to the vane (12), and also causes a change of volume of a bearing fluid chamber (21, 21', 81), which in turn effects a supply of bearing fluid to the slide bearing fluid film.
