    Abstract: A multi-chamber impeller pump includes an impeller, circumferentially spaced cams defining an impeller chamber, and circumferentially spaced evacuation ports. Each cam includes an engagement edge, an arcuate cam surface sloping radially inward, and a lobe. Each evacuation port is proximal to an intersection of a respective arcuate cam surface and lobe. As the impeller rotates, a corresponding end of a leading blade contacts a respective engagement edge and then a corresponding end of a trailing blade contacts the respective engagement edge thereby forming a unit chamber between leading and trailing blades. As the impeller continues to rotate, the end of the leading blade contacts a respective lobe and displaces the leading blade to decrease the volume of the unit chamber and expel fluid from the unit chamber through a respective evacuation port. A method of using the multi-chamber impeller pump is also disclosed.

    Abstract: The invention relates to a rotary sliding vane machine (1) for fluid processing, comprising a housing (2) with a cavity (4) with a rotor (9). Vanes (12) are arranged in outwardly directed slots (13) in the rotor (9), and relative sliding between the vanes and the rotor provides spaces with variable volumes in the rotational direction. Each vane is supported by a vane bearing apparatus (102) comprising a slide bearing body (105) with a slot (13) forming a slide bearing for the vane (12), and a cylindrical convex face (116) facing away from the slot (13), and, on each side of the slot (13), a pivot bearing pad (106) with a cylindrical concave face (117) facing the slide bearing convex face (116), forming a pivot bearing for the vane.

    Abstract: A positive displacement machine such as a pump or compressor has a drum-like housing having an interior, circular-cylindrical surface symmetrical about a main axis and having a pair of interior, planar, side surfaces normal to the main axis. A drumlike rotor is mounted within the housing for rotation relative thereto about the main axis and has an exterior, circularcylindrical surface approximately fitting the interior, circularcylindrical housing surface. Also, the rotor has a pair of exterior, planar, side surfaces approximately fitting the interior, planar, side surfaces of the housing. Around the rotor is a peripheral groove symmetrical about a plane normal to the main axis and disposed between the planar side surfaces of the rotor. A ring having peripheral gaps therein is mounted on the housing and projects into and substantially occupies the groove. There are axially undulatory walls on the rotor defining a channel forming approximately sinusoidal pockets disposed on opposite sides of the ring and open thereto. The pockets have circumferentially overlapping portions and are circumferentially displaced from each other. The pockets when considered together have a substantially constant axial dimension. Vanes having substantially the same axial dimension are mounted on the housing for pivotal motion through the gaps and in the pockets as impelled by the channel walls. There are ports in the housing on axially opposite sides of the ring and on circumferentially opposite sides of the vanes defining inlet and outlet passages open to the pockets.
