Liquid trapping suction accumulator - has J-tube with slight bend on inlet side to prevent alignment of inlets

摘要

An improved liquid trapping suction accumulator is used intermediate the compressor and evaporator in a vapour-compression refrigerator 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 includes a 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.
