The present invention relates a liquid-ring pump, in which the impeller (5) of the pump is rotatably arranged in the pump chamber formed by the pump housing (2), and the pump chamber is closed off by a disk cam 6 which has at least one inlet slit (8) and several output ports (10). Arranged between the disk cam (6) and a side shield (1) covering this disk cam is a suction chamber (7), connected to the inlet slit (8), and a pressure chamber (9), connected to the output ports. At least one of the output ports (10) is covered by a valve plate which may be moved away from this output port and be supported on a collector plate (12) affixed to the housing. The assembly of the valve plate is facilitated in that the collector plate (12) is connected to the side shield (1), and the valve plate (11) is guided by guide elements (14) penetrating through corresponding openings (15) in the valve plate (11), which openings are arranged between the collector plate (12) and the disk cam (6).
A liquid-ring pump having a chamber formed by the pump housing, rotatably accommodating an impeller, and closed off at least no one front end by a disk cam 6 and being covered by a side shield, said disk cam having at least one inlet slit and several output ports, and said side shield being configured on the pump housing, and forming a suction chamber between it and the disk cam such that the inlet slit provides an opening to the suction chamber and forming a pressure chamber such that the output ports provide an opening to the pressure chamber, at least one of the output ports being covered by at least one valve plate which can be moved away from the at least one of the output ports and be supported on a collector plate affixed to the housing,
