HYDRODYNAMIC BEARING

摘要

A hydrodynamic bearing has a fixed bearing element having a bearing surface adapted to support a rotatable member, the bearing surface having an inlet zone and an outlet zone spaced from the inlet zone in the direction of rotation of the rotatable member and a groove therein adjacent the inlet zone to which oil is supplied. A pressure limiting valve limits the pressure of oil at the inlet zone and has an outlet communicating with the outlet zone.
