Abstract

PURPOSE: To prevent a lubricated part from a supply shortage of oil due to foaming of a refrigerant, by extending a gas relief hole in the exact opposite direction to the eccentric direction of a supply oil hole to be opened to outside a main shaft and forming said gas relief hole in the half way of the supply oil hole in the main shaft.
CONSTITUTION: A compressor forms a gas relief hole 29, extended in the exact opposite direction to the eccentric direction of a supply oil hole 23 and opened to outside a main shaft, in the half way of the supply oil hole 23 in the main shaft 6. The compressor, forming in an upper end part of the supply oil hole 23 a gas reservoir 30 communicating with the gas relief hole 29 through the supply oil hole 23, enables lubricating oil to be surely supplied to a bearing 18, being a lubricated part, by discharging high pressure gas to outside the main shaft from the gas relief hole 29 even if a pressure in the gas reservoir 30 increases due to foaming of a refrigerant in the supply oil hole 23.
