ABSTRACT:
In a conically or cylindrically ported liquid ring pump, compressed gas that would otherwise be carried over from the compression zone to the intake zone of the pump is made to bypass the intake zone by passing through a first aperture in the port member into a clearance between the rotor shaft and the port member and then through a second aperture in the port member from the clearance to an initial portion of the compression zone.
