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.

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 lower end plate cover is provided with a bulging portion. In a circumferential direction of a rotary shaft, a plurality of bolt holes includes a first bolt hole arranged between a distal end portion and a proximal end portion of the lower discharge valve, a second bolt hole arranged in a position adjacent to the first bolt hole on a side close to a lower vane groove with respect to the first bolt hole, and a third bolt hole arranged in a position adjacent to the first bolt hole on a side away from the lower vane groove with respect to the first bolt hole. When the bulging portion is divided into a first bulging portion and a second bulging portion using a first straight line, the first bulging portion is larger than the second bulging portion.
