摘要： A variable capacity rotary compressor to prevent an eccentric bush and a locking pin from being deformed or worn out due to a variance in a pressure of a compression chamber as a rotating shaft rotates. The compressor includes upper and lower compression chambers having different interior capacities thereof, and a rotating shaft. Upper and lower eccentric cams are provided on the rotating shaft to be eccentric from the rotating shaft in a common direction. Upper and lower eccentric bushes are fitted over the upper and lower eccentric cams, respectively, with a slot provided at a position between the upper and lower eccentric bushes. The locking pin operates to change a position of the upper or lower eccentric bush to a maximum eccentric position. Further, surfaces of parts around first and second ends of the slot are heat-treated, thus increasing a hardness thereof.

摘要： A variable capacity rotary compressor is designed to prevent eccentric bushes from slipping during a compression operation, thus preventing noise from being generated and increasing durability. The compressor includes a housing to define two compression chambers having different capacities therein. A rotating shaft is rotated in the compression chambers. Two eccentric cams are mounted to the rotating shaft. Two eccentric bushes are rotatably fitted over the eccentric cams. Two rollers are rotatably fitted over the eccentric bushes. Two vanes are installed in the compression chambers to be reciprocated in a radial direction of the rotating shaft. A cylindrical connecting part integrally connects the eccentric bushes to each other, with a locking slot being provided around the connecting part. A locking pin is mounted to the rotating shaft to project from the rotating shaft, and is locked by either of opposite ends of the locking slot, according to a rotating direction of the rotating shaft, thus making one of the eccentric bushes eccentric from the rotating shaft while making a remaining one of the eccentric bushes be released from eccentricity from the rotating shaft. A restraining unit outwardly moves from the rotating shaft by a centrifugal force when the rotating shaft is rotated, to restrain the connecting part.

摘要： A variable capacity rotary compressor including upper and lower compression chambers in which compressing operations are carried out. A slot is provided at a predetermined position between upper and lower eccentric bushes. A locking pin makes either of the upper and lower eccentric bushes be disposed at a maximum eccentric position. Since the locking pin has a diameter which is larger than a locking hole in a shaft by about 0.02 mm to 0.06 mm, the locking pin is fitted into the locking hole in a press-fit method. Further, the locking hole has a threaded part and a non-threaded part, and the locking pin has a threaded part to correspond to the threaded part of the locking hole and a non-threaded part to correspond to the non-threaded part of the locking hole.
