SELF-PRIMING CENTRIFUGAL LUBRICATION PUMP FOR A TURBO CHARGER

摘要

In a self-priming centrifugal lubrication pump of an exhaust gas turbocharger, the pump rotor is fastened on the turbocharger shaft between two shaft bearings. A stationary oil ring channel is located on a larger diameter outside a rotating annulus of oil, which channel is connected via an oil branch pipe and an oil pressure pipe to the injection nozzles located at the side of the shaft bearings.
