Abstract
A positive displacement pump comprising an enclosure having parallel walls and a plurality of concentric annular rings reciprocally mounted between said walls is disclosed. By reciprocating the rings in a predetermined sequence, fluid is caused to flow through a series of radially propagating chambers defined by the rings.
Claims11
A radial wave pump comprising:
- an enclosure having parallel walls;
- at least three rings, each ring having two radial faces, an inner cylindrical wall and an outer cylindrical wall, said rings being reciprocably mounted within the enclosure and the inner cylindrical wall of the innermost ring defining an inner chamber and the outer cylindrical wall of the outermost ring defining an outer chamber;
- means for reciprocating the rings in an equally spaced-apart phase relationship, adjacent rings having inner and outer cylindrical walls closely spaced to one another so that fluid is substantially prevented from passing therebetween;
- and
- means secured to both radial faces of each ring for substantially preventing the flow of fluid between the radial face and the opposed wall during a portion of the reciprocation cycle.

A pump for fluids comprising:
- at least three annular rings disposed concentrically about a common axis;
- an enclosure including at least one end plate and having a port communicating with the interior of the innermost ring;
- and
- means for reciprocating said rings in a repetitive sequence so that the rings each engage the plate during a portion of their respective cycles and in combination with the plate define a volume which moves inwardly or outwardly to transfer the fluid between the enclosure outside the outermost ring and the interior of the innermost ring to provide a pumping action.

A pump for fluids, said pump comprising:
- an enclosure including two spaced-apart parallel plates, at least one of said plates having a first port therethrough, and an outer wall extending between said parallel plates and having a second port therethrough;
- at least three concentric annular rings mounted within said chamber to reciprocate between said parallel plates, each of said rings including means to seal against the parallel plates as that ring approaches within a predetermined distance of the plate, adjacent of said rings forming a seal therebetween to prevent the flow of fluid;
- and
- means to reciprocate the annular rings in a predetermined phased relationship.
