ABSTRACT:
A positive displacement rotary device and method of use are provided. The rotary device includes coupled chamber halves with a drive disc having at least one drive plate rotatably engaged with the drive disc. The drive disc is mounted on a drive shaft and positioned between the coupled chamber halves. The drive plates include at least two drive lobes with the drive plates rotating about an axis of rotation 90° and tangent to the drive shaft axis of rotation while the drive disc sweeps the drive plates around the drive shaft. The chamber halves include camming chambers that are shaped to follow the path of the drive lobes on the drive plates as they are swept around the drive shaft. The rotary device can be used as a motor, a pump, or even an internal combustion engine.
