項１記載のオイルフイルタ。[Claims for Utility Model Registration] (1) A solid separation unit for separating solid foreign matter from oil and a gas separation unit for separating gaseous foreign matter from oil are built into one container, and the An oil filter for causing oil introduced into a container to pass through the solid separation unit and the gas separation unit in this order, and separating the oil into oil containing a large amount of gaseous foreign matter and oil containing almost no gaseous foreign matter, and leading the oil out of the container; The gas separation unit includes a cylindrical inverted cup-shaped case disposed inside the solid separation unit and having an inlet for tangentially introducing the oil;
The case includes a conical porous wall disposed within the case to define a swirling flow chamber, and a thin tube disposed on the central axis of the swirling flow chamber to lead out the oil containing a large amount of the gaseous foreign matter. An oil filter characterized in that a plurality of small holes penetrating the wall are provided at intermediate positions of the conical inclined surface. (2) The oil filter according to claim 1, wherein the plurality of small holes have diameters that gradually increase toward the apex of the porous wall.
