ABSTRACT:
An oil filter comprising a housing opened at one end, a first separator unit in the housing for removing solid contaminants from the oil, a mount block for the housing and a second separator unit for removing gaseous contaminants. The first separator unit comprises a cylindrical filter element defining a central space therein, and the mount block is formed with a recess in which the second separator unit is disposed. The second separator unit includes a chamber arranged to generate a vortical flow in the oil introduced therein to thereby separate gas-rich oil which gathers in an axially central portion of the chamber, means for introducing the oil from the central space to the chamber, a first outlet member for leading the oil containing little gaseous contaminants and a second outlet member for discharging the gas-rich oil.
