Abstract
Abstract The expansion of a low boiling point refrigerant is converted into useful work by supply of heat energy to the refrigerant internally of an expansible chamber type of prime mover. The heat energy is derived from an electrical source regulated by a power control which also governs circulation of the refrigerant through a refrigeration cycle and generation of heat to pressurize the refrigerant for injection into the working chamber of the prime mover.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
120 words
A power generating system comprising an expansible chamber device having a working chamber, means for injecting a refrigerant into the working chamber, means connected to the injecting means for preheating the refrigerant to vaporize and pressurize the same prior to introduction into the working chamber, said vaporized refrigerant being introduced into the working chamber at a pressure insufficient to produce expansion of the working chamber, means for heating the vaporized refrigerant internally of the working chamber causing volumetric expansion thereof, means connected to the expansible chamber device for removing heat from the refrigerant exhausted from the working chamber following said expansion thereof, and recirculating means for inducing flow of the refrigerant to the preheating means from the heat removing means.
Claim 2
Dependent Claim
120 words
