。[Claims for Utility Model Registration] 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,
An oil filter that allows oil introduced into the container from the outside to pass through the solid separation unit and the gas separation unit in this order, and separates the oil into oil containing a large amount of gaseous foreign matter and oil containing almost no gaseous foreign matter, and the oil is led out from 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 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 by having a parabolic cross-sectional shape on its central axis.
