Abstract
An integrated bearing and pump assembly is formed by positioning a hydrodynamic pump coaxially with respect to a hydrodynamic bearing. The integrated assembly provides pressurized fluid for use within the device incorporating the bearing. The hydrodynamic pump comprises a secondary hydrodynamic bearing incorporated into the primary bearing assembly. The secondary bearing is optimized for high flow pumping applications rather than the high pressure, zero flow requirements of the primary bearing. When the bearing assembly is rotated, fluid flow is provided.
