OIL CENTRIFUGAL CLEANING FILTER WITH PRELIMINARY STARTING Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to lubrication systems of internal combustion engines employing full-flow centrifugal filters. Proposed centrifugal oil filter has union to supply compressed air with electromagnetic valve, bushing rigidly secured on rotor axle, impeller, with impeller hub and housing forming sliding pair and their end face surfaces forming space coupled with engine oil main line through radial and axial holes, thus providing unmeshing of teeth on impeller disk and rotor cap after starting of engine. EFFECT: improved efficiency of cleaning of oil fed to friction units at engine starting. 1 dwg
