Claims

[Scope of utility model registration request]

An oil separator device for separating oil components from blow-by gas, which is installed on a cylinder head cover of an engine that is installed at an angle when mounted on a vehicle, and has an opening on the lower side of the slope on the lower surface of the top wall of the cylinder head cover. A U-shaped frame plate is provided protrudingly facing the frame plate, a horizontal plate is provided protrudingly located between the pair of side walls of the frame plate, and a bottom plate is placed on the lower ends of the frame plate and the horizontal plate. As a result, a U-shaped flow path is formed, and a pair of partition plates are provided protruding from the upper surface of the bottom plate to separate the space between one side wall of the frame plate and the horizontal plate and between the other side wall of the frame plate. The upper end of the partition plate and the cylinder head cover are positioned between the side wall and the horizontal plate in a direction intersecting therewith to sequentially define the U-shaped flow path into first to third separation chambers. A gap is provided between the lower surface of the ceiling wall for the passage of gas components, and a gap is provided between the side end of the partition plate and the frame plate and the horizontal plate for the return of the oil component. Two vertical plates having the same height and substantially parallel to each other are provided between the frame plate and the horizontal plate on the inclined lower side of the third separation chamber to form an outlet, and An oil separator device for an internal combustion engine, characterized in that an oil return hole is formed in the lower part and an expansion chamber is formed between these vertical plates.
