摘要： A compressor includes a rotary shaft, a cam, a cylinder block, pistons, a thrust bearing, a rotary valve, and an oil passage. The rotary shaft has an in-shaft passage formed therein. The cam rotates integrally with the rotary shaft. The pistons are coupled to the rotary shaft through the cam. The thrust bearing is provided between the cam and the cylinder block. The thrust bearing includes a first race in contact with the cam, a second race in contact with the cylinder block, and rolling elements retained between the first and second races to form a gap therebetween. The oil passage extends from the gap to the in-shaft passage and includes an oil retaining space formed in at least one of the cam and the cylinder block.

摘要： A compressor includes a housing, compression unit, discharge chamber, outlet, and oil separation structure. The oil separation structure, which is arranged between the discharge chamber and the outlet, includes an oil reservoir, oil separation compartment, intake passage, exhaust passage, and supply passage. The oil separation compartment is located upward from the oil reservoir. The intake passage, which extends upward from the oil separation compartment, draws refrigerant gas into the oil separation compartment from the discharge chamber to separate lubrication oil from the refrigerant gas. The exhaust passage extends upward from the oil separation compartment and discharges the refrigerant gas in the oil separation compartment out of the housing through the outlet. The supply passage extends upward from the oil separation compartment and has a larger cross-sectional area than the intake passage. The supply passage supplies the oil reservoir with lubrication oil from the oil separation compartment.

摘要： A scroll type compressor includes a housing, fixed and orbiting scroll members, a rotary shaft, a drive bushing, a plain bearing, a boss, a drive mechanism accommodation space and a compression chamber. The rotary shaft includes an eccentric pin on which the drive bushing is rotatably fitted. The boss is formed in the orbiting scroll member. The drive bushing is slidably inserted in the boss. In the drive mechanism accommodation space formed by the housing, the eccentric pin, the drive bushing and the bearing are disposed and upstream and downstream spaces are defined by the bearing. The compression chamber is formed by the fixed and the orbiting scroll members. A clearance is formed facing the sliding surface of the bearing. A communication passage is formed in the orbiting scroll member for communication between the compression chamber and the upstream space or the clearance and is opened toward the bearing.

摘要： A scroll compressor includes an orbiting scroll member, a drive mechanism accommodation space, a rotary shaft, a drive bushing, an upstream space, a downstream space, a first communication passage and a second communication passage. The upstream space and the downstream space are formed in the drive mechanism accommodation space by a plain bearing, the drive bushing and an eccentric pin of the rotary shaft. The second communication passage passes through at least the drive bushing and allows the upstream space and the downstream space to communicate with each other. A control valve is disposed in the second communication passage. Centrifugal force of the control valve developed when the rotary shaft is rotated at a predetermined speed or higher causes the control valve to move in a direction in which the second communication passage is opened, thereby to allow the upstream space and the downstream space to communicate with each other.
