Abstract
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.
