Abstract
Abstract There is provided an improved energy converting system for converting low temperature heat energy into mechanical energy. The energy converting system includes an absorption system including a carrier fluid and a working medium absorbable by the carrier fluid. Evaporator means receives the low thermal energy and converts the working medium from a liquid to a gas. The gaseous working medium is then absorbed by the carrier fluid, and the concentrated mixture of working medium and carrier fluid goes into a separator wherein the medium and fluid are separated by compression. A condenser means is provided for removing heat from the gaseous working medium and thereby converting the gaseous working medium into a liquid. Energy converting means are provided associated with one of the above means for converting the energy in the system into other forms of energy, such as into mechanical energy.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
An energy converting system for converting energy from a relatively low thermal source into useful energy comprising: a carrier fluid; a compressible working medium absorbable by said carrier fluid and convertible between the liquid and gaseous states; evaporator means receiving heat energy from a relatively low thermal source for transferring the working medium from the liquid to the gaseous states; absorption means connected to receive the gaseous working medium from said evaporator and to receive said carrier fluid for absorbing the gaseous working medium into said carrier fluid to provide a concentrated fluid-medium mixture; separator means receiving the concentrated fluid-medium mixture separating the working medium from said concentrated fluid-medium by compressing the concentrated fluid-medium mixture; conduit means returning said carrier fluid from the separator to said absorption means; condenser means discharging heat energy connected to receive the working medium from said separator means for converting the gaseous working medium to a liquid state; conduit means connecting said condenser means to said evaporator means; energy converting means operatively connected with said separator means between the said absorption means and the said condenser means for converting energy from said working medium to another form of energy.
Claim 2
Dependent Claim
194 words
An energy converting system for converting energy from a relatively low thermal source into useful energy comprising: a carrier fluid; a compressible working medium absorbable by said carrier fluid and convertible between the liquid and gaseous states; evaporator means receiving heat energy from a relatively low thermal source for transferring the working medium from the liquid to the gaseous states; absorption means connected to receive the gaseous working medium from said evaporator and to receive said carrier fluid for absorbing the gaseous working medium into said carrier fluid to provide a concentrated fluid-medium mixture; separator means receiving the concentrated fluid-medium mixture separating the working medium from said concentrated fluid-medium by compressing the concentrated fluid-medium mixture; conduit means returning said carrier fluid from the separator to said absorption means; condenser means discharging heat energy connected to receive the working medium from said separator means for converting the gaseous working medium to a liquid state; conduit means connecting said condenser means to said evaporator means; energy converting means operatively connected with said separator means between the said absorption means and the said condenser means for converting energy from said working medium to another form of energy.
