Abstract
A system of bypass passages adjacent bearing means in the drive system of an ultracentrifuge which operates in a vacuum environment. The bypass passages or channels are designed to prevent the establishment of a pressure differential across the bearings in the drive system when a vacuum is being pulled or exists around the drive system when it is operating. The unique bypass system prevents the loss of lubricating material within the drive system during air evacuation of the drive system and the rotor chamber when a vacuum environment is being established within the rotor chamber. Also, the bypass system promotes a more uniform and constant flow of lubricating medium in the bearings.
