Abstract

A bottom lid body 12 for dividing the inside at an interval from the upper wall of a cylinder head cover 11 is fixed. An oil separation chamber 13 is formed between the bottom lid body 12 and the cylinder head cover 11. A collar piece 19 for cutting off scattered oil from the lower portion generated by centrifugal force in a camshaft B, a cam C, and the like is provided at one side of a drain hole 18 provided at the lower end of a drain pipe 17 that is perpendicularly provided from the bottom lid body 12.

Description

technical field [0001] The present invention relates to an oil separator device for separating lubricating oil contained in piston ring blow-by gas leaking from the inside of an engine. technical background [0002] In the engine for vehicles, in order to prevent air pollution, when the piston ring blow-by gas leaked from the engine is returned to the intake pipe again, the mist lubricating oil contained in the piston ring blow-by gas is separated and returned to the suction pipe. Oil separator device on the sliding part side of the engine. [0003] Figure 8 Among them, the existing oil separator device is formed by aluminum die-casting or polyamide, polyacetal and other synthetic resins, and the bottom is open, inside the box-shaped cylinder head cover 1, and the The upper wall partitions the inner bottom cover body 2 at intervals, and a lubricating oil separation chamber 3 is formed between the bottom cover body 2 and the upper wall of the cylinder head cover 1 . Inside...
