    • A device in a vacuum pump (23) of the liquid-ring type, serving a pulp pump and having a cylindrical vacuum chamber (25) and an impeller (26) eccentrically journalled in the vacuum chamber to rotate therein together with a liquid ring (29). According to the invention a channel (50) is arranged in the cylindrical wall (30) of the vacuum chamber, said channel having a first section (51) that is located within a converging pressure space (33) of the vacuum chamber and is in open communication therewith, and a second section (52) that is located within a diverging suction space (34) of the vacuum chamber and is in open communication therewith. A valve means (53) is arranged in the pump housing (24) between the channel sections (51, 52) in order, in a first position, to close the connection between them and thus the connection between the pressure and suction spaces and, in a second position, to open said connections, whereby pressure equalisation is achieved and the vacuum function ceases temporarily.

    • A multiple flow, liquid ring pump has a roctor housing (1) that encloses the rotor of the pump. A shield (2 or 3) which projects at least partially over the rotor housing (1) in the radial direction is arranged on each front side of the rotor housing (1). Both shields (2 and 3) project over the rotor housing (1) at the same point of its circumference, and each shield (2 or 3) is provided with an inlet (7) and an outlet (8) in their projecting part (corner 16), on the side that faces the other shield (2 or 3). In this pump, the opposite inlet and outlet (7 and 8) of the shields (1 and 3) are interconnected by connecting tubes (9) that extend parallel to the rotor housing (1). A suction opening (13) is provided for a supply line and a delivery opening (14) is provided for an outlet line. This liquid ring pump takes up little space and can be easily mounted at its installation site.

    • The problem of space and weight limitations for liquid ring pumps and regenerative pumps in aerospace applications is solved by a pump having a housing defining a first chamber (22) and a second chamber (24) independent of the first chamber. An impeller (10) is rotatably mounted in the housing and includes impeller blades (16) successively movable through the first chamber for cooperation therewith to provide a liquid ring portion of the pump, and through the second chamber for cooperation therewith to provide a regenerative portion of the pump. An inlet admits fluid to the first chamber. A first outlet from the first chamber feeds the fluid to an inlet of the second chamber for pressurization therein. An outlet from the second chamber feeds the pressurized fluid for appropriate use, such as in a fuel pump system. A dual pump configuration also is contemplated with a pair of first chambers (22, 22a) and liquid ring portions of the pump, and a pair of second chambers (24, 24a) and regenerative portions of the pump. The fluid in the dual ring pump portions is fed to one of the liquid compressor portions and then to the other regenerative pump portion for doubling the effectiveness of the pump. All of this is accomplished by a unitary housing and a single impeller.

    • A regenerative pump (1) and method of discharging pressurized fluid therefrom wherein direct flow of pressurized fluid from side channels (10, 11) of the pump into discharge ports (16, 17) of the pump is blocked by walls (18, 19) of the pump casing (2) thereby requiring the pressurized fluid to flow into the space between the blades (4) of the impeller of the pump and radially inward to the discharge ports to provide a more ordered flow at the discharge port while improving the self-priming capability of the pump. The cross-sectional area of each of the side channels (10, 11) is progressively reduced in the vicinity of the discharge ports by tapering inwardly the radially outer walls (26, 27) of the casing defining the side channels for facilitating movement of the pressurized fluid into the impeller and to the discharge ports in a controlled manner. The discharge ports are each shaped such that its radially outer edge (23) is progressively more radially outward in a direction from the upstream end (25) of the discharge port to the downstream end (24) thereof for optimizing the gas pumpiping ability, with a minimum loss of liquid for improved performance of the pump as both a liquid ring pump for gas and as a side channel pump for liquid.
