Oil separator

Abstract

An object of the present disclosure is to increase, in an oil separator, the removal efficiency of the oil contained in target gas. The oil separator according to the present disclosure includes: a plurality of separation disks that are rotatable together with a spindle and that are laminated in an axial direction of the spindle; a nozzle that is projected from a part of a peripheral surface of the spindle, the part being located below with respect to the separation disks, and that injects oil from an injection hole to rotate the spindle around an axis; and a housing that includes a cylindrical side wall and defines a chamber accommodating the spindle, the separation disks, and the nozzle. The oil separator is characterized in that a plurality of longitudinal ribs extending in the vertical direction are circumferentially formed on the inner surface of a body cover (the side wall).

Dependencies are inferred from the claim text.
