Compression Part: Notes
WARNING: This page is about a different car, the 2017 Kia Niro. However, it is still accessible from the selected car via links, so may be relevant.
One of the scrolls is fixed while the other orbits eccentrically without self-rotating, thereby to trap and pump refrigerant in the pockets between the scrolls.
