Abstract
Abstract In conjunction with a heat engine such as a turbine in which the medium expands and is cooled while giving up energy, which uses a closed system in which the medium is cooled so that the vaporized medium condenses to fluid, a heat pump is used in which the medium is transported by a compressor utilizing an ejector, particularly an ejector having at least two nozzles for injection of liquid working medium, with the temperature of the working medium fed to the two nozzles being different from each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
242 words
A heat engine for transforming heat energy into mechanical work by circulating a working medium within a closed system, said heat engine comprising a means for transforming heat energy in a working medium into mechanical work, said means including a working medium inlet and a working medium outlet, the working medium undergoing an expansion and a temperature decrease while passing through said transforming means; a compressor means connected to the working medium outlet of said transforming means, said compressor capable of increasing the pressure of said work medium passing therethrough; a cooler means connected to said compressor means, said cooler means capable of cooling a portion of said working medium passing therethrough into liquid form; a separator means connected to said cooler means capable of separating the liquified working medium from the non-liquified working medium delivered from said cooler means; means for delivering the non-liquified working medium from said separator means to said working medium inlet of said transforming means; means for delivering the liquified working medium from said separator means to said compressor means; means in said means for delivering the liquified working medium from said separator means to said compressor means for increasing the temperature and pressure of said liquified working medium; and said compressor means comprising an ejector including an envelope and a discharge nozzle within said envelope, said means for delivering the liquid working medium from said separator means to said compressor means being connected to said nozzle.
Claim 2
Dependent Claim
242 words
A heat engine for transforming heat energy into mechanical work by circulating a working medium within a closed system, said heat engine comprising a means for transforming heat energy in a working medium into mechanical work, said means including a working medium inlet and a working medium outlet, the working medium undergoing an expansion and a temperature decrease while passing through said transforming means; a compressor means connected to the working medium outlet of said transforming means, said compressor capable of increasing the pressure of said work medium passing therethrough; a cooler means connected to said compressor means, said cooler means capable of cooling a portion of said working medium passing therethrough into liquid form; a separator means connected to said cooler means capable of separating the liquified working medium from the non-liquified working medium delivered from said cooler means; means for delivering the non-liquified working medium from said separator means to said working medium inlet of said transforming means; means for delivering the liquified working medium from said separator means to said compressor means; means in said means for delivering the liquified working medium from said separator means to said compressor means for increasing the temperature and pressure of said liquified working medium; and said compressor means comprising an ejector including an envelope and a discharge nozzle within said envelope, said means for delivering the liquid working medium from said separator means to said compressor means being connected to said nozzle.
Claim 3
Dependent Claim
15 words
A heat engine as claimed in claim 1 wherein said transforming means comprises a turbine.
Claim 4
Dependent Claim
69 words
A heat engine as claimed in claim 1 wherein at least one additional discharge nozzle is placed within said envelope of said ejector, and wherein at least one additional means are provided for delivering liquified working medium from said separator means to said compressor means, each additional delivery means being connected to a separate discharge nozzle, the working medium being supplied to the various nozzles being at different temperatures.
Claim 5
Dependent Claim
39 words
A heat engine according to claim 3 wherein at least one of said additional discharge nozzles comprises a plurality of discharge outlets spaced in a downstream path relative to the direction of flow of working medium through said ejector.
