Embodiment Construction

[0021] Such as figure 1 , figure 2 As shown, the piston type internal combustion engine oil-gas separator of the present invention includes a conduit 1, a cover plate 3, a liquid storage bottle 4, a bracket 5, a gasket 6, and also includes a spiral coil 7 bent into a helical shape by a plastically deformable pipe . The nozzle at the lower end of the conduit 1 passes through the cover plate 3, and the conduit 1 is connected with the cover plate 3 and the seams are sealed. The spiral coil 7 is located above the cover plate 3 , the lower end nozzle of the spiral coil 7 passes through the cover plate 3 , and the spiral coil 7 is connected with the cover plate 3 and the seams are sealed. The liquid storage bottle 4 is installed on the lower side of the cover plate 3, and a gasket 6 is arranged between the mouth of the liquid storage bottle 4 and the cover plate 3. The function of the gasket 6 is to seal the gap between the cover plate 3 and the 4 bottlenecks of the liquid storag...

Abstract

The invention relates to an oil-gas separator of a piston internal combustion engine. The oil-gas separator comprises a guide pipe 1, a cover plate 3, a liquid storage bottle 4, a support 5, a gasket 6 and a spiral coil 7. A pipe opening in the lower end of the guide pipe 1 penetrates the cover plate 3 and is connected with the cover plate 3. The liquid storage bottle 4 is arranged on the lower side of the cover plate 3. The gasket 6 is arranged between a bottle opening of the liquid storage bottle 4 and the cover plate 3. The support 5 is provided with a hoop 5-1, a screw hole 5-2 and an installing hole 5-3. The hoop 5-1 surrounds the periphery of the cover plate 3 and the periphery of the bottle opening of the liquid storage bottle 4. The spiral coil 7 is located above the cover plate 3. A pipe opening in the lower end of the spiral coil 7 penetrates the cover plate 3 and is connected with the cover plate 3. The oil-gas separator of the piston internal combustion engine is arranged on the outer side of the piston internal combustion engine and has the beneficial effects that the structure is simple, the manufacturing cost is low, the oil-gas separation effect is good, engine oil emulsification is prevented, and the liquid storage bottle 4 is convenient to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of crankcase ventilation of piston internal combustion engines, in particular to an oil-gas separation device used in the crankcase ventilation system of piston internal combustion engines of automobiles. Background technique [0002] During the working process of the automobile piston internal combustion engine, a small amount of mixed gas in the cylinder will escape into the crankcase through the gap between the piston ring and the cylinder wall, the gap between the piston ring cutouts, etc. If the mixed gas that has escaped into the crankcase is not drawn out, it will cause the crankcase The internal pressure rises, causing oil leakage from sealing structures such as oil seals. Therefore, automobile piston type internal combustion engine crankcase is all provided with ventilation system, and ventilation system leads the mixed gas that escapes into crankcase to the piston type internal combustion engine in...
