Abstract
Scroll compressors may preferably include, for example, a stationary scroll, a drive shaft member, a movable scroll, a bearing member, a compression chamber, a discharge port, a discharge valve and a discharge valve clamping device. The drive shaft member may revolve around a revolution axis. The bearing member may be disposed between the movable scroll and the drive shaft member in order to transmit the revolution of the drive shaft member to the movable scroll. The compression chamber may be defined by a space formed between the stationary scroll and the movable scroll. The compression chamber compresses the fluid drawn into the compression chamber when the movable scroll revolves or orbits with respect to the stationary scroll. The discharge port is disposed within the movable scroll and is adapted to discharge fluid within the compression chamber to the opposite side of the stationary scroll. The discharge valve clamping device is preferably affixed to the movable scroll. The discharge valve clamping device may prevent the discharge valve from moving together with the bearing member when the bearing member accidentally or unintentionally revolves together with the drive shaft m…
