Abstract
The disclosure provides rotary machines that include, in one embodiment, a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first hub disposed thereon with a plurality of cavities. At least one contour is slidably received into an arcuate cavity in an exterior surface of the hub. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume.
Claims19
A rotary machine, comprising:
- a) a stationary housing defining an inwardly facing continuously curved surface;
- b) front and rear side plates attached to the stationary housing component;
- c) a rotatable shaft defining a central axis A, the rotatable shaft having a first end and a second end, the rotatable shaft having a first hub disposed thereon, the first hub having a body with a volume generally defined between front and rear surfaces that are spaced apart along the rotatable shaft, the perimeters of the front and rear surfaces defining at least one radially outwardly facing concavity through the hub configured to slidably mate with at least a portion of a first contour assembly, the first hub being situated axially between the front and rear side plates;
- d) a plurality of rollers disposed within said at least one radially outwardly facing concavity;
- and
- e) wherein the first contour assembly is movably disposed on the plurality of rollers disposed within said at least one radially outwardly facing concavity defined on the first hub, the first contour assembly being defined by a pair of opposed outwardly facing front and rear surfaces and convex radially inwardly facing and convex radially outwardly facing surfaces, the convex radially inwardly facing surface of the first contour assembly facing the at least one radially outwardly facing concavity of the first hub, the convex radially outwardly facing surface, the front and rear side plates and the inwardly facing continuous curved surface of the stationary housing cooperating to form a working volume, the rotatable shaft and first hub being configured to rotate with respect to the stationary housing and front and rear side plates, wherein:
- the first contour assembly oscillates on the plurality of roller bearings within the concavity of the hub as the hub and rotatable shaft rotate;
- and
- first and second lateral ends of the first contour assembly seal against the inwardly facing continuous curved surface of the housing component as the rotatable shaft rotates.
