Abstract:
There is disclosed a scroll compressor capable of improving the oil separating device of a refrigerant gas discharged from a scroll compression element to effectively suppress the amount of oil to be discharged through a discharge tube. The scroll compressor has, in a sealed container, a scroll compression element, a motor element which drives the scroll compression element, and a support frame having a bearing portion which keeps a shaft of the motor element, and provided with a communication path. The scroll compressor further includes a shield plate which extends from the support frame to the motor element side to surround the periphery of the bearing portion, and a guide member provided at an outlet of the communication path to guide the discharged gas in the direction of the shield plate.
