| Number | Title | Issue Date |
| 7421982 | Independent combustion chamber-type internal combustion engine The present invention is directed to an internal combustion engine for making suction, compression, explosion, expansion and exhaust strokes in an operating chamber of variable volume defined between a housing and a piston. The internal combustion engine includes: a... | 09/09/2008 |
| 6886326 | Quasi-isothermal brayton cycle engine An engine includes a compressor, and combustor, and an expander. The compressor compresses ambient air. The combustor burns the compressed air, and produces exhaust gasses. The expander receives the exhaust gases from the combustor, and expands the exhaust gasses. T... | 05/03/2005 |
| 5115775 | Internal combustion engine with multiple combustion chambers An internal combustion engine having two separate main combustion chambers isolated from the cylinder and from each other by means of a valve throttle mechanism. Combustion occurs first in one chamber, and then in the other, separated by one complete revo... | 05/26/1992 |
| 4696158 | Internal combustion engine of positive displacement expansion chambers with multiple separate combustion chambers of variable volume, separate compressor of variable capacity and pneumatic accumulator An engine has a compressor of variable capacity under command of a control system that regulates the output of the compressor for maintaining constant, at an adjustable value, the air pressure supplied from the compressor to plural combustion chambers of ... | 09/29/1987 |
| 4646693 | Rotary engine A twin rotor engine has a combustion chamber in which the fuel and air mixture is periodically exploded, and an inlet valve selectively delivers the expanding gasses to an expansion chamber defined by a housing and by the rotors. An outlet valve serves to... | 03/03/1987 |
| 4133172 | Modified Ericsson cycle engine A modified Ericsson cycle engine, the operating cycle of which involves sequential modes of substantially adiabatic compression, constant pressure heat addition, constant temperature expansion, heat rejection at constant volume and heat rejection at const... | 01/09/1979 |
| 4024703 | Combustion in combustion products pressure generator intermittent burner type and engines This invention comprises improvements in combustion products pressure generators of the intermittent cycle, two stage type and reciprocating piston engines which use the combustion products the pressure generators produce for power to drive compressors wh... | 05/24/1977 |
| 4024704 | Combustion products pressure generator continuous burner type and engines This application pertains to reciprocating piston engines supplied hot pressure fluid medium by combustion products pressure generators and controls thereof. This invention pertains to a new improved electro magnetic operated automatic, reversible cut off... | 05/24/1977 |
