Scroll type compressor with improved lubricating arrangement for movable parts thereof

Abstract From the Canadian patent

In a scroll type compressor, a movable scroll is engaged with an immovable scroll so that spaces are formed for taking in a fluid including a lubricating oil mist to be compressed. The movable scroll is revolved around a central axis of the immovable scroll so that, as the spaces are displaced toward a center of the immovable scroll, a volume thereof is reduced to compress the fluid therein.
