Abstract
A lubrication system for a centrifugal liquid processing apparatus or the like having a bearing subject to operation in a centrifugal force field includes a reservoir wherein a quantity of fluid lubricant to be applied to the bearing is contained, an accumulator for receiving lubricant from the bearing, a first flow path from the reservoir through the bearing to the accumulator, and a second flow path from the accumulator to the reservoir. During operation of the apparatus lubricant is forced by the centrifugal force field to flow along the first flow path from the reservoir, through the bearing and into the accumulator under pressure. When the apparatus is stopped, lubricant is forced to return from the accumulator along the second flow path to the reservoir. An orifice is provided in the first flow path to control the flow and pressure of the lubricant within the bearing, and check valves are provided to restrict the lubricant to a circulating route through the bearing.
