Abstract
An accumulator is capable of preventing an excessive enlargement of the flow rate of a liquid refrigerant which is discharged from the accumulator, reducing the quantity of refrigerating machine oil which is accumulated in the accumulator, and maintaining a required quantity of refrigerating machine oil in a compressor. Liquid and a gas which circulate in a refrigerating and air-conditioning circuit are introduced into a first space by a suction pipe, and the gas refrigerant is discharged to a refrigerating and air-conditioning circuit through a gas passage pipe, a second space and a discharge pipe 5. A liquid-level maintaining mechanism prevents a rise in the height of the accumulated liquid introduced into the first space. When the height has been made to be not lower than a predetermined height, a gas communication mechanism moves liquid in the first space from the first space to the second space. A returning mechanism discharges refrigerating machine oil accumulated in the first space to the refrigerating and air-conditioning circuit.
