Rotating cylinder with ports for an internal combustion engine

Abstract

An invention is provided for a new and novel intake/exhaust device for an internal combustion engine. A rotating cylinder having an intake/exhaust port penetrating the outer surface of the rotating cylinder and meet at an axis of rotation and have a connective relationship which allows fluid to flow easily. The rotating cylinder when used in a 4-stroke engine aligns the intake port with the combustion chamber, and when rotated will align the exhaust port with the combustion chamber each at the correct time. This novel invention overcomes the limitations of current valve trains by only using rotation, and not by using rotation and linear motion to activate valves thereby allowing the engine to attain much greater RPMs.

What is claimed, is: 
     
         1 . An intake and exhaust system for an internal combustion engine comprising:
 a. a rotating cylinder, said rotating cylinder having intake/exhaust ports defined therein, said intake/exhaust ports penetrating normal to an outer surface of said rotating cylinder and meeting at a center or axis of rotation, said intake/exhaust ports being separated by an angle and provide a connective relationship allowing fluid to easily flow from one end of the intake/exhaust port in the rotating cylinder to the other end without restriction;   b. said rotating cylinder has bearing journals extending along said axis of rotation providing support for said rotating cylinder;   c. an intake/exhaust manifold comprising an upper and a lower manifold and having bearing surfaces defined therein, a cylindrical cavity is defined within the intake/exhaust manifold located between the bearing surfaces;   d. said bearing journals of said rotating cylinder are rotateably positioned on said bearing surfaces of said intake/exhaust manifold, said rotating cylinder thereby being located in said cylindrical cavity; and   e. said intake/exhaust manifold having an intake port and exhaust port defined therein, said intake and exhaust port communicating with said cylindrical cavity defined in said intake/exhaust manifold;   
     
     
         2 . The intake and exhaust system as defined in  claim 1  wherein the angle between said intake/exhaust ports is defined as one hundred and twenty (120°) degrees. 
     
     
         3 . The intake and exhaust system as defined in  claim 1  wherein said outer surface of said rotating cylinder has at least three slots defined therein, said slots being the full length of said rotating cylinder and each slot having a blade seal slideably positioned therein creating at least three discreet chambers between said outer surface of said rotating cylinder and said cylindrical cavity in said exhaust manifold, said blade seals preventing leakage between each discreet chamber. 
     
     
         4 . The intake and exhaust system as defined in  claim 1  wherein the intake/exhaust ports in the rotating cylinder communicate with an intake port in said intake/exhaust manifold and a cylinder in an internal combustion engine during an intake stroke, the rotating cylinder is rotated and provides no communication between the intake/exhaust ports and said intake or an exhaust port located in said intake/exhaust manifold and said cylinder during either a compression stroke or a power stroke of the internal combustion engine, said intake/exhaust ports communicate with said exhaust port in said intake/exhaust manifold and said cylinder during an exhaust stroke of the internal combustion engine.
