Abstract
A rotary device for use in pumping applications or as an internal combustion engine is disclosed. The rotary device includes a cylinder and first and second axles that rotate within the cylinder. Each axle has a fin set with at least one fin subdividing the cylinder. A drive shaft has a first terminus coupled to the first axle by at least one universal joint and a second terminus coupled to the second axle by at least one universal joint. In one embodiment, the rotary device includes a fluid inlet port and a fluid outlet port formed in a wall of the cylinder. The fluid inlet port allows fluid to enter the cylinder, while the fluid outlet port allows fluid to exit the cylinder. In one embodiment, the rotary device includes a motor operable to rotate the drive shaft, thereby allowing fluid to be pumped into and out of the cylinder. In another embodiment, the rotary device includes an ignition source attached to the cylinder, the ignition source being operable to ignite a fuel within the cylinder.
