Abstract

This oil separator including the following elements: a shell pipe (2) that has a cylindrical internal space and that separates gas and oil in the cylindrical internal space; a gas inlet pipe (5) that introduces gas along a tangential direction of the cylindrical internal space; an approximately-linear oil return pipe (3) that guides oil separated in the cylindrical internal space to the outside; and an approximately-linear gas outlet pipe (4) that is opposed to the oil return pipe (3) and that guides gas separated in the cylindrical internal space to the outside, in which a central axis line (L2) of the gas outlet pipe (4) is provided eccentrically with respect to a central axis line (L1) of the shell pipe (2).
