Abstract
Abstract An absorption refrigeration machine having a generator and condenser on the high side thereof and an evaporator and absorber on the low side employing a pulser-type solution pump to minimize ''''slugging,'''' transfer noncondensible gases and solution from the low side to the high side of the machine, store noncondensible gases on the high side thereof and utilize the collected noncondensible gases to dampen pump discharge pulsations.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
214 words
A pump for use in an absorption refrigeration system comprising a cylindrical casing having a circular bottom closure and a domed top closure, a first partition dividing said casing into a noncondensible gas storage chamber and a second chamber, said first partition being a generally circular member affixed to said cylindrical casing, a second partition associated with said casing and said first partition to divide said second chamber into an inlet chamber and a transfer chamber, said second partition being cylindrical and affixed to said bottom closure and said generally circular first partition, inlet valve means associated with said second partition to allow passage of liquid and gases from the inlet chamber to the transfer chamber, discharge valve means associated with said second partition to allow passage of liquid and gases from the transfer chamber to the storage chamber, means disposed in the transfer chamber for pumping a mixture of liquid and gases from the inlet chamber to the storage chamber, the gases passing into the storage chamber separating from the liquid and collecting in an upper portion of the storage chamber to form a cushioned layer to dampen pump pulsations, and discharge means communicating with the storage chamber closely adjacent with bottom of the chamber of passage of liquid from the discharge chamber.
Claim 2
Dependent Claim
214 words
A pump for use in an absorption refrigeration system comprising a cylindrical casing having a circular bottom closure and a domed top closure, a first partition dividing said casing into a noncondensible gas storage chamber and a second chamber, said first partition being a generally circular member affixed to said cylindrical casing, a second partition associated with said casing and said first partition to divide said second chamber into an inlet chamber and a transfer chamber, said second partition being cylindrical and affixed to said bottom closure and said generally circular first partition, inlet valve means associated with said second partition to allow passage of liquid and gases from the inlet chamber to the transfer chamber, discharge valve means associated with said second partition to allow passage of liquid and gases from the transfer chamber to the storage chamber, means disposed in the transfer chamber for pumping a mixture of liquid and gases from the inlet chamber to the storage chamber, the gases passing into the storage chamber separating from the liquid and collecting in an upper portion of the storage chamber to form a cushioned layer to dampen pump pulsations, and discharge means communicating with the storage chamber closely adjacent with bottom of the chamber of passage of liquid from the discharge chamber.
Claim 3
Dependent Claim
51 words
A pump according to claim 1 wherein said discharge means comprises a tube projecting downwardly through said domed top closure toward said generally cylindrical partition to said casing, the open lower end of said tube being spaced closely adjacent the generally circular partition for passage of liquid from the storage chamber.
Claim 4
Dependent Claim
60 words
A pump according to claim 2, wherein said inlet valve meanS is positioned below the normal level of collected fluid within the inlet chamber but closely adjacent the surface of the fluid so that passage of liquid from the inlet chamber to the transfer chamber creates a vortex to induce gas collected in the inlet chamber into the transfer chamber.
Claim 5
Dependent Claim
36 words
A pump according to claim 2 further including deflector means disposed in the storage chamber opposite said discharge valve means to prevent discharge of liquid from the valve into the upper portion of the storage chamber.
Claim 6
Dependent Claim
25 words
A pump according to claim 2 wherein said means for pumping fluid includes a resilient diaphragm adapted to be cyclically flexed by pulsating hydraulic pressure.
Claim 7
Dependent Claim
28 words
A pump according to claim 5 wherein said resilient diaphragm has a generally cylindrical shape with a hemispherical end thereto, said diaphragm being disposed within said cylindrical partition.
Claim 8
Dependent Claim
35 words
A pump according to claim 6 further including a purge valve affixed to said domed top closure and communicating with the interior of said storage chamber for bleeding excess noncondensible gases from said storage chamber.
