Abstract
Abstract Solution is pumped from the low-pressure side of the system for operating a jet eductor which functions to entrain noncondensable gases in the low-pressure side in the solution passing through the eductor. The solution and entrained gases are discharged from the eductor into a passage means operable to separate the gases from the solution and discharge the gases into the high-pressure side. Purge means is connected to the high-pressure side for venting the gases to the atmosphere.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
50 words
A system as set forth in claim 1 wherein said discharge passage means comprises a vertically disposed tube descending from said generator section and communicating at its lower end with said liquid trap whereby said solution gravitates to said trap and said relatively noncondensable gases ascend to said generator section.
Claim 2
Dependent Claim
34 words
A system as defined in claim 2 wherein said tube comprises an overflow pipe communicating with said generator section at a location such as to establish a maximum solution level in said generator section.
Claim 3
Dependent Claim
65 words
An absorption refrigeration system according to claim 1 wherein said pump has a suction line connected to said absorber section and a discharge line extending to said generator section for the transfer of weak absorbent solution from said absorber section to said generator section, a branch line extending from said discharge line to said eductor for conveying weak solution to said eductor for operation thereof.
