  • Rotating vane compressor with energy recovery section, operating on a cycle approximating the ideal reversed Carnot cycle
    Patent number: 5819554
    Abstract: A rotating vane machine is described in which compression and energy recovery expansion is obtained within one compact design. The machine is operated in conjunction with a new thermodynamic cycle which approaches the ideal reversed Carnot cycle to optimize efficiency. The new cycle simplifies control, and enables the rotating machinery to be of simple construction.
