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.
Claims28
A rotary machine, comprising:
- a substantially toroidal shaped housing defining a chamber between an outer wall of the housing and an inner wall of the housing, the housing having a cap at an end;
- an expansion ring rotatably disposed within the chamber;
- a sealing cylinder mechanically connected to the expansion ring wherein the sealing cylinder and expansion ring form a substantially sealed contact area;
- an intake port adapted to allow the introduction of a first product into the chamber;
- an exhaust port adapted to allow the expulsion of a second product from the chamber;
- and
- an igniter in communication with the chamber to ignite the first product.

- a sealing cylinder mechanically connected to the expansion ring wherein the sealing cylinder and expansion ring form a substantially sealed contact area;
- an intake port adapted to allow the introduction of a first product into the chamber, the first product having an intake volume and an expansion volume;
- and
- an exhaust port adapted to allow the expulsion of a second product from the chamber;
- wherein the ratio of the expansion volume to the intake volume is such that the expulsion of the second product through the exhaust port occurs at approximately ambient pressure.
