SCR Scroll – How It Works

The airend has one orbiting scroll and one fixed scroll. The orbiting scroll is coupled to the crankshaft in orbit rather than rotated. The orbiting motion creates a series of air pockets traveling between the two scroll plates. 

On the outer portion of the scroll, the pocket draws in the air then moves it to the centre of the scroll, where it’s discharged.

As the air moves in the increasing smaller inner pocket, the pressure increases to the desired discharged pressure.
