Claims

[Claims for Utility Model Registration] (1) A cylinder whose both ends are closed by a housing having a bearing portion, a rotating shaft which is supported by the bearing portion of the housing and has an eccentric portion in the middle of rotation within the cylinder; A rolling piston that fits into the eccentric portion of the rotating shaft and rotates along the inner circumferential wall of the cylinder, a compression chamber formed between the rolling piston and the cylinder, and a compression chamber that is connected to a high pressure side and a low pressure side. A vane pressurizes the outer periphery of the rolling piston from the radial direction, a suction hole communicating with the low pressure side of the compression chamber via a suction passage, and a discharge passage connected to the high pressure side of the compression chamber. An open rotary compressor in which the rotary shaft protrudes outward from a closed container housing a discharge hole communicating with the discharge hole and a valve plate for opening and closing the inlet of the discharge hole, and a shaft sealing device for the rotary shaft. A mechanism for supplying oil to a shaft sealing device of an open type rotary compressor, characterized in that a hole provided in the holder of the holder and a hole provided in the housing for supplying oil to a bearing portion are communicated through a pipe. (2) Oil supply to the shaft sealing device of an open rotary compressor according to claim 1 of the utility model registration claim, characterized in that a disc-shaped plate fitted with an O-ring is inserted into the communication pipe. mechanism. (3) The oil supply mechanism for a shaft sealing device of an open type rotary compressor according to claim 1, wherein a groove is provided on the end face of the outer ring of the bearing. (4) A mechanism for supplying oil to a shaft sealing device of an open type rotary compressor according to claim 1, characterized in that a throttle is provided in the middle of the oil supply hole provided in the housing.
