Abstract
Abstract The invention applies to a liquid/vapor energy cycle having a boiler for heating a liquid to produce a vapor for driving a transducer and a way of returning the transducer output to the boiler. A vortex tube receives the output from the transducer and divides the transducer output into relatively hot and cold portions, and an injector is powered by the vapor and arranged for pumping the cold portion of the transducer output back into the boiler. The hot portion of the transducer output is preferably used for powering the injector, and a portion of the vapor from the boiler can assist in this.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
70 words
In a liquid/vapor energy cycle including means for heating a said liquid in a boiler to produce said vapor and a transducer driven by said vapor, the improvement comprising: a. a vortex tube arranged for receiving the output from said transducer and dividing said transducer output into relatively hot and cold portions; and b. an injector powered by said vapor and arranged for pumping said cold portion into said boiler.
Claim 2
Dependent Claim
70 words
In a liquid/vapor energy cycle including means for heating a said liquid in a boiler to produce said vapor and a transducer driven by said vapor, the improvement comprising: a. a vortex tube arranged for receiving the output from said transducer and dividing said transducer output into relatively hot and cold portions; and b. an injector powered by said vapor and arranged for pumping said cold portion into said boiler.
Claim 3
Dependent Claim
