Abstract
A rotary device is described for use in a rotary engine, or a compressor, or turbine, the rotary device comprising two rotors disposed adjacent each other and rotatable about substantially parallel axes of rotation. Each of the rotors has protrusions extending therefrom at regular intervals about the circumference of each to define an open portion of a sealable compression chamber between adjacent protrusions. Each protrusion has two side surfaces and a projecting end surface, wherein the meeting point between each side surface and the projecting end surface defines a tip. The two rotors are arranged such that upon contra rotation of the rotors, a protrusion of one of the rotors engages between a pair of protrusions on the other rotor, and the tips of the engaging rotor are in constant sealing contact with the opposing side surfaces of the pair of protrusions for a predetermined period of time. During the predetermined period of time, a sealed chamber is formed and the volume of the chamber is reduced to a predetermined level by the contra rotation.
