ABSTRACT:
A filtering apparatus for removing impurities out of a lubrication oil for use in an internal combustion engine including low and high density filters having inlets commonly connected to an inlet conduit through which the lubrication oil to be filtered is supplied, an orifice arranged in an outlet conduit of the low density filter to produce a reduced pressure due to a fast oil flow and a conduit connected between an outlet of the high density filter and the orifice. Due to the reduced pressure applied to the outlet of the high density filter, a part of the oil is effectively sucked into the high density filter.
