Liquid trapping suction accumulator

Claim 1

A liquid trapping suction accumulator adapted for insertion in a vapor-compression refrigeration system between the evaporator and the compressor, comprising: A. an accumulator chamber defined by a casing having a top closure and a bottom closure; B. inlet and outlet ports in said top closure opening into said chamber and respectively adapted for operative connection to said evaporator and said compressor; C. an outlet connector in said outlet port; D. a J-shaped tube mounted within said casing; and i. the long leg thereof extending into and terminating in said outlet connector centrally positioned within and in peripherally spaced relationship from the internal surface of said outlet port; ii. inwardly extending dimples spacedly positioned about the inner periphery of said outlet connector and providing an interference fit with the outer diameter of said J-tube outlet end for rigid support thereof in said connector, the spacing between the dimples creating a predetermined open area therebetween for exiting gas; iii. the outlet end of said J-tube being outwardly flared to a controlled diameter for coacting with said dimples in an interference fit therewith; and iv. the short leg thereof terminating in an inlet opening directly centrally aligned with said inlet port and in spaced relation therefrom.
