ABSTRACT:
An improved liquid trapping suction accumulator of the type used intermediate the compressor and evaporator in a vapor-compression refrigeration system as a protective device for the compressor. The device provides for minimal pressure drop in the system while still performing the function of compressor protection, and provides for safe removal without "slugging" of accumulated oil and/or liquid refrigerants from the accumulator chamber. The structure is characterized by J-shaped tube mounted within the accumulator with a bent short leg extending above the accumulator bottom; also, by a cylindrical interference jib of the J-shaped within the accumulator outlet, so as to control the size of the vent.
