Abstract
The Present system provides for expanding high pressure gases from the chambers of a moving rotor and reentering said gases into the chambers of said moving rotor in such a way that the gases in the chambers of said moving rotor have been subjected to more expansions than the gases reentering the chambers and therefore are at a lower pressure than the gases reentering said chambers.

A method for effecting a multi-staged expansion and reentry of high pressure gases from and into the chambers of a moving rotor comprising the steps of:
- a. expanding some of said gases from the chambers of said moving rotor thereby effecting once expanded gases;
- b. reducing, simultaneously with step (a), the pressure of said gases remaining in said chambers of said rotor thereby effecting once reduced pressure gases in said chambers;
- c. expanding some of said once reduced pressure gases, in said chambers, from said chambers thereby effecting gases which have been subjected to two pressure reductions.
- d. reducing, simultaneously with step (c), the pressure of said once reduced gases remaining in said chambers of said rotor thereby effecting twice reduced pressure gases in said chambers;
- e. reentering said once expanded gases into the chambers of said moving rotor upon the completion of step (d).
In a rotary type engine which has a stator and a rotor, said stator having first and second sections disposed respectively on first and second sides of said rotor, and which rotor has a plurality of chambers and wherein each of said chambers has a gas inlet end and a nozzle of reduced cross-sectional area terminating in an outlet end and wherein said chambers are successively loaded, as they rotate past a selected location, with high pressure gases, means for effecting a multi-staged expansion of said high pressure gases comprising in combination:
- first gas expansion port means formed in said first section of said stator and disposed to receive gases from said outlet ends of said nozzles, which are rotated to be open to said first gas expansion port, whereby said gases passing through said nozzles experience a first expansion and are expanded into said first gas expansion port means and whereby gases which do not pass through said nozzles but remain in said chambers experience a first reduction in pressure;
- second gas expansion port means formed in said first section of said stator and disposed in close proximity to said first gas expansion port means and further formed and disposed to receive gases from said outlet ends of said nozzles, which are rotated to be open to said second gas expansion port, whereby said gases passing through said nozzles experience a second expansion and are expanded into said second gas expansion port means and whereby gases which do not pass through said nozzles but remain in said chambers experience a second reduction in pressure;
- first gas reentry port means formed in said second section of said stator and disposed to reenter gases onto said rotor through said gas inlet ends of said chambers, said first gas reentry port means disposed to reenter said gases, which experienced said first expansion, into said chambers which hold gases that have experienced said second reduction in pressure;
- first gas return means connected between said first gas expansion port means and said first gas reentry port means to conduct said gases, which experienced said first expansion, to said first gas reentry port means.
