To prevent degradation in reliability of a compressor, caused by approach of a passage of liquid refrigerant flowing from a suction pipe to an opening part of an outlet pipe so that the liquid refrigerant is directly sucked from the outlet pipe and is compressed, in an accumulator for a multicylinder compressor.
A partition board hole 4 formed in a partition board 5 between the suction pipe 2 and outlet pipes 3a, 3b is in a shape of a hemisphere surface. Liquid components of the refrigerant flowing from the suction pipe 2 of the upper center passes through the partition board hole 4. At this time, since the opening part of the partition board hole 4 is the hemisphere surface facing away in a radial direction to make the liquid refrigerant flow outside the accumulator, the liquid refrigerant does not flow into opening parts of tips of the outlet pipes 3a, 3b, and is collected in a lower part of a sealed vessel.
