Abstract
A rotary machine having a housing with rotary components disclosed within. The rotary machine is configurable as an internal combustion rotary engine, an external combustion rotary engine, a gas compressor, a vacuum pump, a liquid pump, a drive turbine, or a drive turbine for expandable gases or pressurized liquids. The combustion engine employs a new thermal cycle—eliminating the Otto cycle's internal compression of the combustion products as part of the cycle. The new combustion thermal cycle is intake, expansion and exhaust.
Claims10
A method of employing a rotary machine to produce rotary power, comprising:
- igniting combustive products to generate an increased pressure caused by expansion of the combustive products;
- directing the increased pressure into a rotatable expansion ring;
- rotating the expansion ring a distance proportional to the increased pressure to accommodate the expanding combustive products;
- and
- exhausting the combustive products,
- wherein the combustion products are introduced at about ambient pressure.
