Title: Scroll pump
Inventor: ALAN ERNEST KINNAIRD HOLBROOK
IPC: F04C28/26
Filed: 2020-11-05
Abstract: A scroll pump 100 and method of operation are disclosed. The scroll pump 100 comprises an orbiting scroll 130 biased against an intermeshing fixed scroll 120 having a pumping space in between. A recirculation channel 190a extends from the pumping chamber to an inlet of the pump. A valve 190b is disposed in the return line 190a which permits flow through when a pressure across it is equal to or exceeds a threshold value. The recirculation channel 190a may be positioned in either the fixed 120 or orbiting 130 scroll. The arrangement allows for high pressures to be relieved by the ‘blow-off’ valve and so prevent scroll lift-off occurring so that the sealing of the pump is improved. The valve may open at a pressure difference of between 100mbar and 400mbar. These values relate to the minimum pressure difference to a deliver significant and effective reduction in scroll lift-off and the maximum difference that would be generated by such a pump.
