Description
Technical field
The utility model relates to the valve mechanism cover technical field of structures in ventilation system for automobile crankcase, relates in particular to a kind of valve mechanism cover of integrated Oil-gas Separation.
Background technique
When motor car engine is worked, always some flammable mixed gas and waste gas channel in crankcase through piston ring, and mixed gas can reduce machine oil quality by oil dilution, shorten machine oil working life.In waste gas, contain water vapour and sulfur dioxide, water vapour condenses in and in machine oil, forms greasy filth, clogged oil line; Sulfur dioxide is met water and is generated sulphurous acid, and sulphurous acid is met airborne oxygen, generates sulfuric acid, and acidic materials not only can make machine oil rotten, also can corrode component.Meanwhile, mixed gas channels in crankcase, and crankcase pressure is increased, and also likely causes the oil sealing place generator oil seepage phenomenon of crankcase, and atmosphere is produced to serious pollution.Too high for preventing crankcase pressure, extend machine oil life time, reduce parts wear and corrosion, prevent engine oil leakage, must give crankcase ventilation.
China Patent Publication No. 101631946, open day on January 20th, 2010, a kind of valve mechanism cover of internal-combustion engine is disclosed, its collection chamber by induction system of internal combustion engine is configured in the outer surface side of roof of the valve mechanism cover of coating gas cylinder cap, and in the inner surface side of the roof of valve mechanism cover, form the ventilation chamber of blow-by gas, roof form with the opposed part of collection chamber the concave surface roof that becomes concave surface with respect to collection chamber, on this concave surface roof, be formed with the recess of further recessed valve mechanism cover inner surface side.The valve mechanism cover separation oil and gas weak effect of this internal-combustion engine.
Model utility content
The utility model is in order to solve the deficiency of existing valve mechanism cover separation oil and gas weak effect, a kind of good oil gas separation effect to be provided, and by two-stage separate mode, the oil gas in mixed gas is carried out to the valve mechanism cover of fully separated a kind of integrated Oil-gas Separation.
To achieve these goals, the utility model is by the following technical solutions:
A kind of valve mechanism cover of integrated Oil-gas Separation, comprise baffle of porous baffle, left separating plate, right separating plate, between interlayer, be provided with the double Shell of cavity, baffle of porous baffle is fixedly installed in the cavity of double Shell, baffle of porous baffle is separated into left disengagement chamber and right disengagement chamber the cavity of double Shell, left separating plate and right separating plate are separately fixed on the internal face of left disengagement chamber and right disengagement chamber, on the inner plating of double Shell, be provided with the inlet hole communicating with right disengagement chamber, on the inner plating of double Shell, be also provided with the oil return slotted eye communicating with left disengagement chamber and right disengagement chamber, on the lamina rara externa of double Shell, be respectively equipped with two air outlet holes that communicate with left disengagement chamber.
This programme good oil gas separation effect, carries out abundant separation by two-stage separate mode the oil gas in mixed gas.Specifically first allow mixed gas enter right disengagement chamber and carry out first separation, then allow mixed gas after right disengagement chamber separation enter left disengagement chamber and carry out secondary separation, after this twice separation, the Oil-gas Separation in mixed gas is more thorough.The air induction hose and the intake manifold that gas after separation are incorporated into respectively to motor car engine, be incorporated into the oil after separation in the oil sump of motor car engine.
As preferably, the upper end of right separating plate is fixed on the inner top surface of right disengagement chamber, and the lower end of right separating plate is toothed edge.Oil easily flows down from the toothed edge of right separating plate lower end, and mixed gas is when toothed edge reflects away, and can allow the angle at mixed gas reflection edge inconsistent, makes so right separating plate better to the oil gas separation of mixed gas.
As preferably, the lower end of left separating plate is fixed on the inner bottom surface of left disengagement chamber, and the upper end of left separating plate is provided with breach, is horizontally installed with rolling post in breach, on rolling post, is fixed with guide vane.Mixed gas enters after left disengagement chamber, the power that mixed gas clashes into can allow rolling post roll, the another side that guide vane on rolling post can be brought into left separating plate the mixed gas that will leave left separating plate carries out Oil-gas Separation, be equivalent to mixed gas and carried out Oil-gas Separation twice at left disengagement chamber, once on the right surface of left separating plate, to have carried out one time Oil-gas Separation, another time is on the left surface of left separating plate, to have carried out again one time Oil-gas Separation, better to the oil gas separation of mixed gas like this.
The utility model can reach following effect:
The utility model good oil gas separation effect, carries out abundant separation by two-stage separate mode the oil gas in mixed gas.Specifically first allow mixed gas enter right disengagement chamber and carry out first separation, then allow mixed gas after right disengagement chamber separation enter left disengagement chamber and carry out secondary separation, after this twice separation, the Oil-gas Separation in mixed gas is more thorough.
