摘要：
A scroll type compressor comprising a fixed scroll and movable scroll. The movable scroll revolves above an axis of the fixed scroll. Thus, a spiral portion of the movable scroll slides and moves relative to a spiral portion of the fixed scroll so as to compress a refrigerant gas between the spiral portions. A sealing member is mounted on the free end of each sealing member. The sealing member slides on a facing surface of the opposing scroll. An oil passage is provided in at least one of the scrolls. The oil passage opens at the rear surface of the sealing member and is able to supply lubricating oil to the rear surface. A constriction is provided in the oil passage. The constriction limits the flow of the lubricating oil towards the sealing member.
