Rotary sliding vane machine with hydrostatic slide bearings for vanes

摘要

The present invention relates to a rotary sliding vane machine 1 for fluid handling comprising a housing 2 with a cavity 4 with a rotor 9. The vanes 12 are arranged in the outward slot 13 of the rotor 9, and the relative sliding between the vanes and the rotor provides a space having a variable volume in the direction of rotation. Each vane is supported by hydrostatic slide bearings 20, 20' on each side of the vane 12. Due to the pressure change in the process fluid, the vanes 12 tilt towards the bearing pads 27, 27', 87 and away from the bearing pads. The present invention allows the bearing pad to adjust its position with respect to the vane 12, causing a volume change in the bearing fluid chambers 21, 21', 81, which in turn affects the supply of bearing fluid to the slide bearing fluid membrane.
