Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.With
Lower embodiment is used for illustrating the present invention, but is not limited to the scope of the present invention.
Such as a kind of integrated form H type fluid valve device of Fig. 1 to 3, including device body 1, it is unusual
Part is: be provided with air filter union joint 2 in the side of device body 1, device body 1 opposite side is provided with
Inlet manifold union joint 3.Meanwhile, it is provided with venturi between air filter union joint 2, inlet manifold union joint 3
Tubular construction 4, on this venturi tube structure 4, vertical conducting connects the adsorbent chamber having at least two independence, is divided into master
Adsorbent chamber 5 and secondary adsorbent chamber 6.Further, main adsorbent chamber 5 has canister joint with being jointly connected in secondary adsorbent chamber 6
7, in air filter union joint 2, secondary adsorbent chamber 6, it is provided with check valve.Specifically, air filter union joint it is positioned at
In 2 is main check valve 8, be positioned at secondary adsorbent chamber 6 for secondary check valve 9.In view of integrated design,
Reduce space hold, have good air-flow simultaneously and move towards planning, canister joint 7 and venturi tube structure 4
Parallel point of arrangement.
From the point of view of the present invention one preferably embodiment, for the ease of opening smoothly under the effect of pressure differential
Close, it is achieved effective control of vacuum, check valve includes valve block 10.Specifically, this valve block 10 connects
It is connected to locator card connected components 11.Corresponding, it is provided with in air filter union joint 2, secondary adsorbent chamber 6
Holding tank.Thus, locator card connected components 11 embeds in holding tank.So, in routine use, even if going out
The biggest gas shock, can also ensure that valve block 10 does not falls off.Meanwhile, it is distributed on valve block 10 and adds
Strong muscle (not shown).So, when in use will not be because of bigger pressure differential or air-flow occur

From the point of view of further, in order to be stably connected with other pipelines of follow-up composition system, will not use
There is release failure in period, and the present invention is on air filter union joint 2, inlet manifold union joint 3, canister joint 7
It is provided with connection positioning component 12.Certainly, it is contemplated that pipeline connecting structure on the market is different, employing
Connecting positioning component 12 can be positioning threads.And, it is contemplated that the connection of some special tectonic needs, also
Positioning step can be used to constitute and to connect positioning component 12.
The operation principle of the present invention is as follows:
As in figure 2 it is shown, under engine idling operation operating mode, closed throttle, inlet manifold end is formed very
Empty.Thus, under differential pressure action, main check valve 8 is opened, the fuel vapor in extraction canister.Meanwhile,
Secondary check valve 9 is closed due to differential pressure action, stops air to enter inlet manifold.In such manner, it is possible to
Utilize the vacuum of inlet manifold to greatest extent.
Then, when electromotor is in non-idling operation, air throttle is opened.Now, supercharging in inlet manifold
Gas pressure is more than atmospheric pressure.During this period, main check valve 8 is closed, and stops air-flow toward canister interface side
To flowing.Meanwhile, secondary check valve 9 is opened, and by Venturi effect under fluid valve effect, drives air-flow
Drive pumping airflow, to canister purge oil gas, finally enter electromotor, as shown in Figure 3.
By above-mentioned character express and combine accompanying drawing it can be seen that use after the present invention, gather around and have the following advantages:
1, solve the problem that engine with supercharger canister oil gas Extracting Ability is not enough, can realize under electromotor full working scope
Extraction canister oil gas.
2, cooperating of two check valves is used, it is achieved the alternately folding under different operating modes, it is possible to simplify pipe
Road system, reduces cost.
3, being compared to traditional vacuum pump, overall implementation cost is only the former 1/10th, it is easy to push away
Extensively.
4, overall structure is simple, and overall dependability is high, meets the application of variety classes vehicle.
5, use integrated design, reduce and vehicle space is taken, and regular maintenance is the most convenient.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that
For those skilled in the art, on the premise of without departing from the technology of the present invention principle, also
Can make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
