Abstract
A liquid-ring compressor having a rotor mounted in a compressor housing. The rotor is mounted eccentrically relative to the center axis of the compressor housing. At least one control disk is arranged on one of the end faces of the rotor. The control disk is provided with a suction slot and a pressure slot for the feed and discharge of the medium to be compressed, respectively. The control disk also has an encircling distribution groove in the area covered radially by the hub of the rotor. Operating liquid is introduced into a feed opening, which leads to the distribution groove, to seal an axial gap between the control disk and the rotor hub. A blocking element projects radially into the distribution groove and is provided on the side of the feed opening that has the greater pressure differential between the pressure of the operating liquid entering the feed opening and the pressure in the rotor cells. The blocking element improves the sealing of the axial gap.
