ABSTRACT OF THE DISCLOSURE An improvement in an oil filter is provided, the oil filter being of the type which comprise a housing opened at one end thereof, a cylindrical first separator unit disposed in the housing for removing solid contaminants from the oil introduced into the housing, and a second separator unit disposed within the first separator unit for removing gaseous contaminants from the oil that has passed through the first separator unit, the second separator unit including a funnel-shaped cyclone defining a chamber arranged to generate a vortical flow of the oil introduced therein to thereby separate gas-rich oil and a removal pipe extending into the chamber along an axial center thereof for discharging the gas-rich oil. The improvement comprises a wall of the cyclone defining the chamber having a lower portion and an upper portion, and a plurality of pores formed in the lower portion for allowing the oil to flow out of the cyclone. The removal pipe includes an upper end portion positioned above the lower portion of the wall of cyclone, the upper end portion being formed with a plurality of orifices for permitting the gas-rich oil to flow into the removal pipe. The pores and the orifices are arranged in such a manner that they do not overlap with each other in the axial direction of the chamber. The improved oil filter ensures a sufficient and smooth separation of the gaseous contaminants from the oil.
