Combination liquid trapping suction accumulator and evaporator pressure regulator device

Claim 1

A liquid trapping suction accumulator adapted for insertion in a vapor-compression refrigeration system between the evaporator and compressor, comprising: A. an accumulator chamber defined by a casing having a top and a bottom; B. inlet and outlet ports in the top, and opening into said chamber and respectively adapted for operative connection into said evaporator and said compressor; C. removable adaptor means forming an evaporator pressure regulator chamber positioned in said outlet port in communication with said accumulator chamber; said adaptor means being further characterized as i being threadably removably positioned adjacent the top of said accumulator chamber, ii containing an evaporator pressure regulator device in compressive sealing relationship to the adaptor means so as to gauge admission of vapor through said evaporator pressure regulator chamber and said outlet; D. a desiccant removably supported in the bottom of said accumulator chamber; and E. an eductor tube extending independently from the bottom of said accumulator chamber being offset in its lower portion to accommodate said desiccant while being in fluid communication with said evaporator pressure regulator chamber.
