ABSTRACT:
An angular cylinder piston combination is disclosed for providing compression and expansion chambers in a large number of items, such as compressors, pumps, internal and external combustion engines, hydrostatic generators, air motors, and the like, in which compression and expansion chambers are formed angularly, inside a cylindrical drum which rotates at substantially uniform velocity "Wo" and connected to the output shaft. The chambers are formed between N outer radial pistons provided by the drum and N inner radial pistons attached to an inner rotor which accelerates and decelerates from zero velocity to a velocity "2Wo" with respect to a stationary housing. The inner rotor comprises a sleeve overlaying the output shaft and rotatably displacable in relationship therewith. A single port per chamber provides intake and exhaust as it comes into juxtaposition with slots, azimouthally cut on the base of a stationary housing. The inner radial pistons, oscillating within the angle subtended between the outer pistons, do not cross the ports. Lubricating oil can then be permitted to run between a pair of sealing elements positioned along those edges of the pistons which slide with respect to other members of the angular cylinder. The application of this angular cylinder provides the basis of an improved Tri-Rotor device.
