The invention relates to a liquid-ring compressor which has a rotor (4) mounted in the compressor casing (1) eccentrically relative to the latter and at least one control disk (5) which is arranged on the one end face of the rotor (4), is provided with a suction and a pressure slot (16; 17) for the feed and discharge of the medium to be compressed and furthermore has an encircling distribution groove (10) in the area covered radially by the hub (9) of the rotor (4), into which distribution groove (10) operating liquid is introduced as sealing liquid via a feed opening (11). The sealing of the axial gap between the control disk and the rotor hub is improved owing to the fact that a blocking element (18) projecting radially into the distribution groove is provided in the area of the side of the feed opening (11) on which the greater pressure difference between the feed pressure of the operating liquid and the pressure in the rotor cells prevails.
