Description
Technical field
The present invention relates to motor car engine, particularly relate to a kind of deaerator.
Background technique
Deaerator on automobile, is mainly used for keeping machine oil to have good greasy property, extends the working life of machine oil; Keep the surface state that each friction pair is good, reduce wearing and tearing and the corrosion of parts; Keep crankcase pressure substantially equal with air, reduce lubricating oil leakage; Mix waste gas is fully recycled, and reduces air environmental pollution, improves motor Economy.
In existing technology, gasoline trap is that oil gas is directly passed through inside parts, temperature by self declines and gaseous state machine oil is become liquid, because the time is short, temperature variation is little, cause oil-gas separation efficiency low, the oil vapour pollution environment after the burning of last oil gas is insufficient, machine oil cannot be recycled simultaneously, causes consumption of lubricating oil mistake.
Summary of the invention
The object of the present invention is to provide a kind of deaerator, solving current pole has gaseous state machine oil cooling liquefy machine oil efficiency in separator not high, causes Oil-gas Separation incomplete, the insufficient problem causing environmental pollution of last oil gas burning.
For solving the problem, the technical solution used in the present invention is:
A kind of deaerator, comprise air inlet side cylinder head cover body, oil baffle, crankcase bleed pipe, valve module of voltage regulation and excess pressure valve assembly, the below of described air inlet side cylinder head cover body is provided with encapsulate sealing gasket and lining, described oil baffle is arranged on the bottom of encapsulate sealing gasket, described valve module of voltage regulation is arranged in the PCV hole above air inlet side cylinder head cover body, is made up of successively from top to bottom the pressure regulator valve film of PVC valve gap, belt supporting frame and PVC spring; Described excess pressure valve assembly is arranged in the OPV hole above air inlet side cylinder head cover body, is made up of successively from top to bottom overvoltage valve gap, excess pressure valve spring, excess pressure valve; Described crankcase bleed pipe is connected to the side valve module of voltage regulation of air inlet side cylinder head cover body by joint by engines tail feed channel; The downside of the air inlet side cylinder head cover body adapted with the covering position of described oil baffle is provided with mazy passage, described mazy passage is crisscross arranged by lattice retaining wall face and forms, the entrance of mazy passage is connected to the valve module of voltage regulation connected with crankcase bleed pipe, and outlet is connected to oil cylinder recovery channel.
Further, the lattice retaining wall face in described mazy passage and described air inlet side cylinder head cover body by integral forming, the passage formed by lattice retaining wall face between the entrance and exit of mazy passage is more than two.
Further, described lattice retaining wall face is all arranged in serpentine.
The beneficial effect adopting technique scheme to produce is: direct access is become maze-type structure by the present invention, oil gas is allowed to clash into lattice gear, oil gas is cooled rapidly, too increase the time that oil gas passes through simultaneously, make Oil-gas Separation more abundant, under gravity, from newly getting back to oil cylinder, the not clean-burning machine oil of maximized separation also re-uses, and reduces oil consumption, and decreases environmental pollution.

Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1, Fig. 2 and Fig. 3 show a kind of deaerator of the present invention embodiment: a kind of deaerator, comprise air inlet side cylinder head cover body 1, oil baffle 2, crankcase bleed pipe 3, valve module of voltage regulation and excess pressure valve assembly, the below of described air inlet side cylinder head cover body 1 is provided with encapsulate sealing gasket 7 and lining 8, described oil baffle 2 is arranged on the bottom of encapsulate sealing gasket 7, described valve module of voltage regulation is arranged in the PCV hole above air inlet side cylinder head cover body 1, is made up of successively from top to bottom the pressure regulator valve film 52 of PVC valve gap 51, belt supporting frame and PVC spring 53; Described excess pressure valve assembly is arranged in the OPV hole above air inlet side cylinder head cover body 1, is made up of successively from top to bottom overvoltage valve gap 61, excess pressure valve spring 62, excess pressure valve 63; Described crankcase bleed pipe 3 is connected to the side valve module of voltage regulation of air inlet side cylinder head cover body 1 by joint 4 by engines tail feed channel; The downside of the air inlet side cylinder head cover body 1 adapted with the covering position of described oil baffle 2 is provided with mazy passage, described mazy passage is crisscross arranged by lattice retaining wall face 9 and forms, the entrance of mazy passage is connected to the valve module of voltage regulation connected with crankcase bleed pipe 3, and outlet is connected to oil cylinder recovery channel.
According to a kind of deaerator of the present invention preferred embodiment, lattice retaining wall face in described mazy passage is integrated with described air inlet side cylinder head cover body 1, and the passage formed by lattice retaining wall face 9 between the entrance and exit of mazy passage is more than two.
According to a kind of another preferred embodiment of deaerator of the present invention, described lattice retaining wall face 9 is all arranged in serpentine.
Working principle of the present invention is:
When oil gas is connected to air inlet side cylinder head cover body 1 in from engines tail feed channel by joint 4 by crankcase bleed pipe 3, and clash into lattice retaining wall face 9, the oil gas that temperature is high runs into the low lattice retaining wall face of temperature, at this moment energy interchange is to reach equalized temperature, so the temperature of high-temperature oil gas will reduce rapidly, oil gas was lengthened by the time of part simultaneously, also just will lengthen cool time, it is more that temperature reduces, and Oil-gas Separation degree is also better.
