Embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of protection of the invention is belonged to.
As Figure 1-5, the integrated gs-oil separator of described cylinder head cover includes cylinder cap cover body 1, pressure regulator valve 2, oil gas point
From device bottom plate 3, crude separation structure 4, smart isolating construction 5, gas blowby outlet 17.
The left back of described cylinder cap cover body 1 is integrally disposed crude separation structure 4, and smart isolating construction 5 is arranged on oil
On gas separating device bottom plate 3, gs-oil separator bottom plate 3 is welded on rear side of the middle part of cylinder cap cover body 1, the rear side of smart isolating construction 5
It is provided with gas blowby outlet 17, gas blowby outlet 17 and pressure regulator valve 2 is installed.
Described crude separation structure 4 includes crude separation chamber 6, crude separation baffle plate I 7, crude separation baffle plate II 8 and constituted, crude separation
The entrance point of chamber 6 is respectively arranged with the crude separation chamber 6 between one piece of crude separation baffle plate I 7, two pieces of crude separation baffle plates I 7 with the port of export
It is staggeredly equipped with crude separation baffle plate II 8 on inwall, at least two pieces of crude separation baffle plate II 8, the height of crude separation baffle plate I 7 is less than
Crude separation baffle plate II 8, so ensure that gas can overflow from the upper end of crude separation baffle plate I 7 and strikes crude separation baffle plate II 8
On.Size is than larger machine oil particle to separate in gas for crude separation structure 4, and gas enters to be impinged upon slightly after crude separation chamber 6
On skimming baffle I 7, crude separation baffle plate II 8, because polylith crude separation baffle plate II 8 is staggered, and gas impinges upon rough segmentation repeatedly
From on baffle plate II 8, to isolate in gas size than larger machine oil particle, so that the purpose of oil gas crude separation is reached, it is this
The crude separation structure of special construction is not only simple in structure, moreover, also have the advantages that separative efficiency is high.
Described smart isolating construction 5 includes smart disengagement chamber 9, felt valve I 10, felt valve II 11, felt valve base 12, described
Smart disengagement chamber 9 be arranged in the rear side of crude separation chamber 6, smart disengagement chamber 9 and be provided with felt valve base 12, felt valve base 12
Felt valve I 10, felt valve II 11 are installed.
Described felt valve I 10, the structure of felt valve II 11 are consistent, by felt valve support 13, felt valve body 14, bullet
Spring 15, pad 16 are constituted, and two felt valve bodies 14 are at least installed on described felt valve base 12, and spring 15 is arranged on felt
In valve support 13, the front end of felt valve support 13 by nut is fixed through the through hole in the middle part of felt valve body 14 and by pad 16
On felt valve body 14.
The smart isolating construction 5 machine oil particle smaller to separate size in gas, main part is felt valve I 10, hair
Felt valve II 11, felt valve body 14 is made up of loose, internal penetrating felt material, and felt valve I 10, felt valve II 11 are main
There are two effects：First, when engine blow-by gas amount is smaller, felt valve I 10, the two ends of felt valve II 11 pressure difference it is smaller, felt
Valve I 10, felt valve II 11 are now in closed mode, and gas completely extends across felt valve body 14, in the process, in gas
The impurity such as machine oil, steam are stopped by felt valve body 14, are built up in felt valve body 14, finally due to the effect of gravity
It is dropped in smart disengagement chamber 9, so as to play the purpose of separation, it is ensured that only clean gas passes through felt valve body 14, separation
Efficiency high.Second, when engine blow-by gas amount increase, felt valve I 10, the pressure difference at the two ends of felt valve II 11 accordingly increase, and work as pressure
When difference is more than 15 pressure of spring in felt valve I 10, felt valve II 11, felt valve I 10, felt valve II 11 are automatically opened up, and are opened
Degree depend on both sides pressure difference and spring 15 pressure, now felt valve I 10, felt valve II 11 serve the work of relief valve
With, it is ensured that the pressure difference of whole gs-oil separator is in rational scope, and now separative efficiency is not significantly reduced, so that
The function that engine is overall is not influenceed, has taken into account separative efficiency and pressure difference the two most important index requests.Such a essence separation
Structure 5 also has another advantage to be the spring 15 only needed to by changing different elastic force and installs varying number felt valve I
10th, felt valve II 11, just can be suitably used for the requirement of different engines, and versatility is high, and adaptation ability is strong.
Embodiment
Crankcase gas blowby enters after the crude separation chamber 6 of crude separation structure 4, impinges upon crude separation baffle plate I 7, crude separation baffle plate
On II 8, because polylith crude separation baffle plate II 8 is staggered, and gas is impinged upon on crude separation baffle plate II 8 repeatedly, and machine oil particle is attached
On crude separation baffle plate I 7, crude separation baffle plate II 8, finally because Action of Gravity Field is low in crude separation chamber 6, and separate larger
The gas of machine oil particle is then entered in the smart disengagement chamber 9 of smart isolating construction 5, when engine blow-by gas amount is smaller, felt valve I
10th, the pressure difference at the two ends of felt valve II 11 is smaller, and felt valve I 10, felt valve II 11 are now in closed mode, and gas is completely extended across
Felt valve body 14, in the process, the impurity such as machine oil, steam in gas are stopped by felt valve body 14, in felt valve sheet
Built up in body 14, finally because the effect of gravity is dropped in smart disengagement chamber 9.When engine blow-by gas amount increase, felt
Valve I 10, the pressure difference at the two ends of felt valve II 11 accordingly increase, and are pressed when pressure difference is more than the spring 15 in felt valve I 10, felt valve II 11
During power, felt valve I 10, felt valve II 11 are automatically opened up, and the degree of opening depends on the pressure difference of both sides and the pressure of spring 15, this
When felt valve I 10, felt valve II 11 serve the effect of relief valve, it is ensured that the pressure difference of whole gs-oil separator is in rational scope
It is interior, and now separative efficiency is not significantly reduced, from without influenceing the overall function of engine, taken into account separative efficiency and
The two most important index requests of pressure difference.By essence separation gas enter gas blowby outlet 17 in, after the pressure regulation of pressure regulator valve 2 from
Discharge gas blowby outlet 17.
The present invention integrates gs-oil separator with cylinder head cover, when cylinder head cover is combined with engine, so that it may be real
The installation of existing gs-oil separator so that install very convenient, meanwhile, it is simple in construction, it is easy to safeguard；And it is integrated on cylinder head cover
Gs-oil separator to oil gas carry out two-stage separation, it is ensured that Oil-gas Separation thoroughly, meanwhile, smart isolating construction include multiple felt valves
Component, such a smart isolating construction also has another advantage to be to only need to the spring and felt valve by changing different elastic force
Quantity, just can be suitably used for the requirement of different engines, and versatility is high, and adaptation ability is strong.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
