Abstract
The utility model discloses an engine cylinder head cover mechanism, which is formed by a cylinder head cover body, a filter screen, a gasket, a one-way valve, a cover plate and a locking component, wherein the cover plate and the gasket are locked on the cylinder head cover body through the locking component; the gasket is closely fit to a clapboard of the cylinder head cover body, so that the gasket and the clapboard in the cylinder head cover body form a simple and connected oil gas passageway; the filter screen is filled in the oil gas passageway; the one-way valve enabling an air inlet or a return port to open monodirectionally is arranged on the air inlet or the oil return port of the cover plate and the gasket. According to the engine cylinder head cover mechanism, engine oil brought from a cylinder head cover is greatly reduced, so that the engine oil consumption of an engine is reduced, the adding times of the engine oil is reduced, the service life of the engine is prolonged, and the environment pollution is reduced, so that the economic performance of the engine is improved.
Description
Technical field
The utility model relates to the technical field of motor, particularly engine cylinder head lid mechanism.
Background technique
The cylinder head cover mechanism 100 of motor is assembled on cylinder head 200, as shown in Figure 1.Cylinder head cover mechanism 100 is made up of cylinder head cover body 10, pad 20, cover plate 30 and lock member 40, as shown in Figure 2.Pad 20 and cover plate 30 are locked on cylinder head cover body 10 by lock member 40, and form the fairway of simple intercommunication with the interior integrated dividing plate 50 of cylinder head cover body 10, this fairway is unimpeded, obstacle is few, and the trend of oil gas in fairway as shown in Figure 3.
When after motor operation, oil gas is in crankcase body is come cylinder head cover mechanism 100, parts of fine oil droplet condenses and flows back to cylinder head by self gravitation effect from three spill ports 60 of cover plate 30, remaining thin oil droplet is directly discharged from oil gas recovery tube 300 along the air outlet 80 of fairway with oil gas, the oil gas of taking out of can arrive Carburetor and carry out secondary combustion, cause the oil consumption of motor to increase, machine oil adds number of times and increases, engine life shortens, befouling environment, such structure reduces the economic performance of motor greatly, therefore need a novel structure to solve above-mentioned problem.
Model utility content
The purpose of this utility model is to provide a kind of engine cylinder head lid mechanism, to reduce the machine oil of taking out of from cylinder head cover.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of engine cylinder head lid mechanism, is made up of cylinder head cover body, filter screen, pad, one-way valve, cover plate and lock member; Cover plate and pad are locked on cylinder head cover body by lock member, and the dividing plate of pad and cylinder head cover body is tightly fitted, and make the fairway of a simple intercommunication of dividing plate formation of pad and cylinder head cover body interior, and filter screen plug are in fairway; The air intake of cover plate and pad or spill port are provided with the one-way valve that makes air intake or the unidirectional unlatching of return port.
Described cover plate and pad are all drilled with four spill ports, and spill port is arranged in fairway and is easy to the lower of oil-collecting.
Described filter screen has three, fills in respectively three positions at fairway.
Described filter screen is metal material.
Described one-way valve is reed.
Described reed is elastic metallic material.
Adopt after such scheme, the utility model in the time that engine interior pressure is malleation, one-way valve opens, oil gas enters in cylinder head cover by the air intake of cover plate, oil gas is separated by filter screen in fairway; In the time that engine interior pressure is negative pressure, one-way valve closure, liquid machine oil after filter screen separates is sucked back in casing by the spill port of cover plate, oil gas only has a fraction of gaseous state machine oil to discharge with waste gas after separating, the machine oil of taking out of from cylinder head cover greatly reduces, the oil consumption, the minimizing machine oil that so reduce motor add number of times, extend engine life, reduce environmental pollution, and the economic performance of motor has improved in such cylinder head cover mechanism.

Embodiment
As shown in Figure 4, a kind of engine cylinder head lid mechanism that the utility model discloses, is made up of cylinder head cover body 1, filter screen 2, pad 3, one-way valve 4, cover plate 5 and lock member 6.
Cylinder head cover body 1 can not made an amendment, consistent with prior art, can reduce Change cost.
Cover plate 5 and pad 3 are locked on cylinder head cover body 1 by lock member 6.Pad 3 is tightly fitted with the dividing plate 7 of cylinder head cover body 1, makes the dividing plate 7 of pad 3 and cylinder head cover body 1 inside form the fairway 8 of a simple intercommunication.
The air intake 51 of cover plate 5 and pad 3 and 31 or spill port 52 and 32 be provided with one-way valve 4, make air intake 51(or 31) can only unidirectionally open (entering gas), or spill port 52(or 32) can only unidirectionally open (oil return), one-way valve 4 specifically can adopt reed, and reed is that elastic metallic material or other have identical or are equal to the material of effect.
Filter screen 2 is filled in fairway 8.In this embodiment, filter screen 2 has three, fills in respectively three positions at fairway 8, makes oil gas separation better by filter screen 2.Filter screen 2 is identical or be equal to the material of effect for metal material or other have.
In order to prevent that better machine oil from taking out of from cylinder head cover, this embodiment is all drilled with four spill ports 52 and 32 at cover plate 5 and pad 3, and spill port 52 and 32 is arranged in fairway 8 and is easy to the lower of oil-collecting, for oil return.
As shown in Figure 5, be the trend of oil gas in fairway 8 and filter screen 2 key plan at fairway 8.
In the time that engine interior pressure is malleation, as shown in Figure 6, one-way valve 4(reed) to open, oil gas enters in cylinder head cover body 1 by the air intake 51 of cover plate 5 and the air intake 31 of pad 3, and oil gas is separated by filter screen 2 fairway 8 is interior; In the time that engine interior pressure is negative pressure, as shown in Figure 7, one-way valve 4(reed) closure, liquid machine oil after filter screen 2 separates is sucked back in casing by four spill ports 52 of cover plate 5, oil gas only has a fraction of gaseous state machine oil to discharge from air outlet 9 with waste gas after separating, the machine oil of taking out of from cylinder head cover greatly reduces, the oil consumption, the minimizing machine oil that so reduce motor add number of times, extend engine life, reduce environmental pollution, the economic performance of motor has improved in such cylinder head cover mechanism.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
