United States Patent Office Issues Patent on CSRV Valve Seal Pressure Regulator.

WALL TOWNSHIP, N.J. -- On April 19th 2005 the United States Patent Office issued patent number 6,880,511 titled "Valve seal assembly for rotary valve engine." The abstract reads as follows; A valve seal for a rotary valve assembly for use in an internal combustion engine of the piston and cylinder type, wherein the cylinder head/combustion chamber is designed for high compression and of long stroke, such as a diesel engine, the rotary valves and the valve seals being positioned in relationship so as to permit charging of the cylinder with a fuel/air mixture and evacuation of spent gases, and to regulate the pressure within the valve seal and valve seat and hence regulate the pressure between the valve seal and the rotary valve.

George Coates, CEO, explained the importance of the patent as it relates to long stroke, high compression ratio engines. "In short stroke engines, the assembly works without modification because of the relatively short stroke of the piston and the resultant pressures developed. However in long stroke engines, such as diesels, in which the compression is significantly greater than in a conventional internal combustion engine, and which compression actually results in the detonation of the fuel/air mixture under significantly higher pressure, the valve seal of a rotary valve assembly for a diesel engine requires a modified structure in that the compression gases would cause excessive pressure on the floating valve seal and its contact with the spherical rotary intake valve or spherical rotary exhaust valve."

Background

Coates International Ltd. (CIL) was incorporated on August 31, 1988 for the purpose of researching, developing, patenting and marketing technology associated with a spherical rotary valve system for internal combustion engines. This technology was developed over 17 years by Mr. George J. Coates, who became the President and Chairman of the Board of CIL. Since the founding of CIL, George Coates has secured fourteen United States patents and a large number of foreign patents for innovations related to the spherical rotary valve internal combustion engine.

The Coates Spherical Rotary Valve System represents a revolutionary departure from the conventional poppet valve. It changes the means of delivering the air and fuel mixture to the firing chamber of an internal combustion engine and of expelling the exhaust produced when the mixture ignites. The "Coates" system utilizes spherical valves which rotate in a cavity formed between a two-piece alloy cylinder head. The valves include channels which connect to the intake and exhaust passages.

The Coates Spherical Rotary Valve System provides benefits of such magnitude that this system will revolutionize engine manufacturing and design. Already, major manufacturers have visited the Coates facility and opened discussions regarding the use of the technology.

The company is now planning the next phase of operation which includes production of large industrial engines and co-generators.
