| 摘要 |
The current invention is a closed cycle heat engine that includes a plurality of variable volume movable working chambers, each chamber having a first volume of working fluid when disposed at an isentropic expansion zone leading edge, a second volume when disposed at an isentropic expansion zone trailing edge, a third volume when disposed at an isentropic compression zone leading edge and a fourth volume of working fluid when disposed at an isentropic compression zone trailing edge. The second volume of working fluid divided by the first volume of working fluid provides a first volume ratio. The third volume of working fluid divided by the fourth volume of working fluid provides a second volume ratio. The first volume ratio equals the second volume ratio. The working fluid efficiently performs work by traversing a cycle consisting of an isothermal expansion, an isentropic expansion, an isothermal compression, and an isentropic compression. |
