An end plate includes a plurality of connection portions coupling a center portion and an outer peripheral portion, and a plurality of through holes formed between the connection portions. The center portion includes a recess portion having a discharge hole, and a fixing hole through which a fixing member for fixing a reed valve to the end plate passes. In a fan-shaped region surrounded by a first half line starting from a center of a shaft hole and passing through a center of the discharge hole, a second half line starting from the center of the shaft hole and passing through a center of the fixing hole, and an outer peripheral surface, the through hole is formed to be continuous in a circumferential direction of the fan-shaped region, and both ends of the through hole in the circumferential direction of the fan-shaped region are located outside the fan-shaped region.

Compressor endplate

A hermetic type compressor includes a compressor main body container that is a vertical type having a cylindrical shape, an accumulator container, a compression section that is arranged inside the compressor main body container, that compresses the refrigerant, which has been sucked from the accumulator container, and that discharges the compressed refrigerant. The accumulator container includes an accumulator shell having a cup shape, and in which an opening side of the accumulator shell is bonded to the compressor main body container. A partition member, which partitions an interior portion of the accumulator shell, is provided in the interior portion, and a thermal insulation section, which includes an interior portion space having a hollow structure that blocks a heat transfer from the compressor main body container to the accumulator container, is formed between the partition member and a bottom shell that is included in the compressor main body container.

A hermetic type compressor includes a compressor main body container that is a vertical type having a cylindrical shape, an accumulator container, a compression section that is arranged inside the compressor main body container, that compresses the refrigerant, sucked from the accumulator container, and that discharges the compressed refrigerant. The accumulator container includes an accumulator shell having a cup shape and a weld portion in which an opening side of the accumulator shell is bonded to the compressor main body container. A partition member, which partitions an interior portion of the accumulator shell, is provided in the interior portion, and a thermal insulation section, which blocks a heat transfer from the compressor main body container to the accumulator container, is formed between the partition member and a bottom shell, included in the compressor main body container. A thermal insulation member is provided in the thermal insulation section.

Hermetic type compressor

A rotary compressor includes a compressor housing that is provided with a refrigerant discharge portion and refrigerant suction portions, a compression unit that is arranged in the compressor housing and compresses a refrigerant, sucked from the suction portions, and discharges it from the discharge portion, a motor that is arranged in the compressor housing and drives the compression unit, an accumulator that is connected to the suction portions, and a mounting member that secures the accumulator to the compressor housing. The compressor housing and an accumulator container of the accumulator are made of a metal material. The mounting member is at least partially made of a resin material and has a first joint portion, which is joined to an outer peripheral surface of the compressor housing.

Rotary compressor

A rotary compressor includes a compressor housing that is provided with a refrigerant discharge portion and a refrigerant suction portion, and an accumulator that is fixed to the outer peripheral surface of the compressor housing and connected to the suction portion. The accumulator has a cylindrical body portion, which is formed of a resin material, an upper portion, which is formed of a metal material and closes an upper end of the body portion, and a lower portion, which is formed of a metal material and closes a lower end of the body portion, the upper portion is joined to the upper end of the body portion, and the lower portion is joined to the lower end of the body portion.
