Abstract (en)

[origin: EP2469202A2] An accumulator (1A,1B) for use in a refrigeration cycle system is constructed to have a liquid accumulating chamber (2) in which refrigerant is accumulated, a refrigerant inlet port (4) through which the refrigerant is led into the liquid accumulating chamber (2), a refrigerant outlet pipe (5) that has an upstream open end (5a) exposed to an upper part of the liquid accumulating chamber (2) to discharge the refrigerant from the liquid accumulating chamber (2) to the outside of the chamber, an oil return opening provided in a given part of the refrigerant outlet pipe to return oil, which is contained in the refrigerant in the lower part of the liquid accumulating chamber, to a compressor of the refrigeration cycle system, a refrigerant flow generating structure that provides the refrigerant from the refrigerant inlet port with a given flow, the given flow being produced by a drive force possessed by the refrigerant; and a refrigerant flow mixing structure that provides the given flow of refrigerant from the refrigerant flow generating structure with an upward-and-downward movement thereby to mix the refrigerant.
