摘要：
[0034] A novel and useful improvement to vane pumps, both variable displacement vane pumps and fixed displacement vane pumps, provides a supply of pressurized fluid to the region within the diameter of the pump rotor which would otherwise be a region of reduced pressure wherein air could be ingested by the pump. By reducing or preventing the ingestion of air, operating noise and damage to the pump can be reduced and wear in an engine or other system supplied from the pump can be reduced. The supply of pressurized working fluid also can be used to lubricate auxiliary components and/or accessories as well. Further, a portion of the supply of pressurized working fluid to this region can act to supercharge the pump, reducing the occurrence of cavitation at higher operating speeds.
