Utility
Flywheel with bifurcated molecular pump
8 Mar 22
A flywheel device that includes a housing that surrounds a vacuum chamber, a flywheel rotor within the vacuum chamber, which rotates during normal operation of the flywheel, thus agitating residual gasses, an exhaust chamber that receives the exhaust gases from the vacuum chamber, and an annular shaped stationary element, within the vacuum chamber that includes scroll channels where some of the scroll channels have an intake port on an inner diameter of the stationary element and some of the scroll channels have an intake port on an outer diameter of the stationary element, and the scroll channels enable gasses to flow from the vacuum chamber, through the scroll channels, into the exhaust chamber.
