    摘要： Purging passages are machined or cast into the casing of a liquid ring compressor through which soluble or nonsoluble contaminants which may be present in the liquid ring may be removed from the compressor. These passages in single lobe pumps are located in the outer peripheral zones of the casing approximately 240* from the pump land in the direction of rotation of the rotor in the area of the drive and idle ends of the rotor.

    摘要： THE PRESENT INVENTION INCLUDES A VACUUM PUMP WHEREIN PASSAGEWAYS ARE FORMED FOR CONTROLLING A PREDETERMINED SHROUD PRESSURE INDEPENDENTLY OF ASSEMBLY CLEARANCES. THIS INVENTION INCLUDES SELECTIVELY ANGULARLY LOCATING PASSAGEWAYS BETWEEN PERIPHERAL LOBE SWEEP CHAMBERS AND ROTOR END FACE CHAMBERS, AND BETWEEN SAID ROTOR END FACE CHAMBERS AND A ROTOR HUB. INTERNAL GAS AND LIQUID LEAKAGE DUE TO PRESSURE DIFFERENTIALS IN RESPECTIVE POSITIONS WITHIN THE PUMP ASSEMBLY IS MINIMIZED.
