Abstract
A compressor has an impeller and an inlet delivering air to the impeller. A variable diffuser is positioned downstream of the impeller and includes a plurality of pivoting vanes. A drive arrangement pivots the vanes, and includes an electric motor causing a pinion gear to rotate. The pinion gear has gear teeth engaging gear teeth on a rack section. Rotation of the rack section causes the vanes to pivot.
