Claim 0:
1. A hermetic compressor comprising:
a vertically cylindrical compressor body vessel in which a compression unit that sucks a refrigerant and discharges the compressed refrigerant into the compressor body vessel, and a motor that drives the compression unit, are accommodated; and
an accumulator vessel that separates gas-liquid of the refrigerant sucked from a refrigeration cycle and supplies a gas refrigerant to the compression unit, and is provided below the compressor body vessel, wherein
the compression unit includes an upper cylinder and a lower cylinder, an upper compression unit suction tube is connected to an upper suction hole of the upper cylinder, a lower compression unit suction tube is connected to a lower suction hole of the lower cylinder,
the accumulator vessel includes a cup-shaped accumulator shell, an opening side of the accumulator shell is fixed by welding to the compressor body vessel,
in the accumulator shell, an accumulator suction tube that sucks the refrigerant from the refrigeration cycle into the accumulator vessel, and an upper gas-liquid separation tube and a lower gas-liquid separation tube that send the gas refrigerant from inside the accumulator vessel penetrate a side wall of the accumulator shell, and are fixed by welding to a first through hole, a second through hole, and a third through hole of the accumulator shell respectively, the upper gas-liquid separation tube is connected to the upper compression unit suction tube via an upper connecting tube outside the accumulator shell, and the lower gas-liquid separation tube is connected to the lower compression unit suction tube via a lower connecting tube outside the accumulator shell.
