Abstract
A device usable as an impeller has a plurality of vanes rotating eccentrically about a shaft. Eccentric rotation is enabled by a cam mounted on the shaft. The vanes are received within slots in a rotor which surrounds the shaft and rotates about an axis coaxial with the shaft. The rotor rotates within a housing having a cylindrical surface facing the rotor. The surface is eccentric to the shaft. The vanes execute reciprocal motion upon rotation of the rotor. The vane motion is constrained so that the edges of the vanes remain proximate to the cylindrical surface during rotation.
Claims38
A device, comprising:
- a shaft defining a shaft axis;
- a cam mounted on said shaft, said cam having a lobe projecting eccentric to said shaft axis;
- a plurality of projections rotatably mounted on said cam, each of said projections being pivotably mounted relative to said cam;
- a rotor surrounding said cam and rotatable relatively thereto about said shaft axis, said rotor comprising a plurality of openings, each said opening receiving one of said projections;
- wherein
- rotation of said rotor relatively to said cam causes said projections to rotate about said shaft axis while also reciprocating within said openings radially toward and away from said shaft axis.
