Abstract
A lubricating mechanism for a scroll-type fluid displacement apparatus is disclosed. A driving mechanism for an orbiting scroll comprises a drive shaft and a drive pin projecting at an eccentric location from an inner end surface of the drive shaft. An annular boss projecting from a circular end plate of the orbiting scroll receives the drive pin. Therefore, the orbiting scroll is rotatably supported on the drive pin. The lubricating mechanism includes an oil passageway formed in the circular end plate of the orbiting scroll to communicate between the interior of the boss and one of the fluid packets located at the outer peripheral portion of the spiral elements. Lubricating oil thus flows into the interior of the boss and lubricates the bearing and other contact surface disposed in the center portion of the apparatus.
