Scroll compressors use two spiral-shaped scrolls to compress air. One scroll remains fixed, while the other moves in an orbiting motion around the center of the stationary scroll. As the scrolls rotate, the …

Often, one of the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid between the scrolls.

These scrolls move in a circular motion instead of upward and downward motion as piston action in a reciprocating compressor. Out of two scrolls, one scroll is a rotatory scroll that rotates using a …
