ABSTRACT:
A rotary mechanism comprising a housing defining an operating chamber, a shaft journalled in the housing and having an eccentric within the chamber, the shaft including an oil passage adapted to receive oil under pressure from a pump or the like and terminating in an opening in the periphery of the eccentric. A rotor is located within the chamber and is journaled on the eccentric and mounts a plurality of seals sealingly engaging the housing at spaced locations and includes plural lubricating conduits for directing oil to at least some of the seals. The conduits terminate in spaced ports facing the eccentric and alignable with the opening therein. An annular bearing is interposed between the eccentric and the rotor to minimize friction thereat. A port extends through the bearing for establishing fluid communication between the opening and the rotor ports. The bearing further includes an annular, radially inwardly opening, oil distributing groove alignable with the opening and a dam in the groove about the bearing port.
