1. A rotary machine, comprising:
a) a rotatable shaft defining a central axis A, the shaft having a first end and a second end, the shaft having an elongate first island disposed thereon, the elongate first island having a body with a volume generally defined between front and rear surfaces that are spaced apart along the rotatable shaft, the front and rear surfaces lying in a plane parallel to a radial axis R, the front and rear surfaces having a rounded, non-circular shape, the perimeters of the front and rear surfaces defining a curved perimeter surface therebetween, the elongate first island defining a plurality of valve cavities therein for receiving rotatable valves; b) a front side plate disposed adjacent to the front surface of the elongate first island; c) a rear side plate disposed adjacent to the rear surface of the elongate first island; d) a first contour assembly disposed between the front side plate and the rear side plate, the first contour assembly being defined by a pair of opposed outwardly facing arcuately shaped front and rear surfaces that are connected by a concave inwardly facing surface, the concave inwardly facing surface of the contour assembly facing the curved perimeter surface of the elongate first island, the concave inwardly facing surface and the curved perimeter surface of the elongate first island and the front side plate and rear side plate cooperating to form a working volume, the rotatable shaft and elongate first island being configured to rotate with respect to the first contour assembly; and e) a plurality of rotatable valves disposed in the valve cavities defined in the island, the rotatable valves being configured to rotate within the valve cavities when the island rotates with respect to the first contour assembly about the central axis. |
