Abstract
Abstract An absorption refrigeration system wherein there is provided in communication with the evaporator, absorber, generator and condenser fluid handling apparatus in the form of a hermetic housing mounting therein a rotatively driven shaft member journaled at opposite ends in bearing means and supporting a plurality of scoop pumps for effecting, among other functions, circulation of refrigerant and absorbent solution through the system, purging, and machine capacity control.

Claim 1
Independent Claim
191 words
An absorption refrigeration system comprising a generator for concentrating absorbent solution by vaporizing refrigerant therefrom to form strong absorbent solution; a condenser connected for condensing refrigerant vapor formed in said generator; an evaporator for evaporating the refrigerant liquid therein; an absorber connected to the evaporator for absorbing refrigerant vapor formed therein; and a hermetically sealed scoop pump connected to said absorber and to said generator for circulating absorbent solution through the system, said scoop pump including a rotatable pan and at least one inlet conduit leading thereto and at least one eduction conduit leading therefrom, means connected to one of said conduits for adjusting the position of the inlet opening thereof relative to the rotating body of solution in said pan so as to control the volume of relatively weak solution passing from the absorber to the generator, thereby controlling the capacity of the absorption refrigeration system; and a second eduction conduit leading from said pan, the position of said second eduction conduit being fixed relative to the pan and being connected with said absorber for recirculating absorbent back to said absorber irrespective of the position of the adjustable eduction conduit.
