Embodiment Construction

[0017] In Fig. 1 to Fig. 4, the oil separator device 10 of the present invention is formed in the box-shaped cylinder head cover 11 with the polyamide resin that contains glass fiber, and the bottom is open. The inner upper wall begins to divide the inner bottom cover body 12 at intervals, and a lubricating oil separation chamber 13 is formed between the bottom cover body 12 and the upper wall of the cylinder head cover 11 . Inside the lubricating oil separation chamber 13, there is a lubricating oil separating mechanism 14 in which a partition plate 14a and a perforated plate 14b are properly arranged in a labyrinth; One side is provided with a tubular outlet 16 penetrating the side wall of the cylinder head cover 11, and on the bottom cover body 12, an oil drain pipe 17 is hung down. 16, the separated lubricating oil is returned to the cylinder head 8 of the engine E. The drain pipe 17 has a lubricating oil storage place with a certain length and diameter and a concave port...

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...
