Into region in.
Preferably, described baffle plate is integrated on inlet manifold body by ultrasonic bonding.
Preferably, described baffle plate is plastic dam.
Preferably, described inlet manifold body is made up of the manifold upper piece and manifold bottom sheet assembly connection being mutually matched,
Wherein, the ventilation interface connected with pressure stabilizing cavity is provided with manifold upper piece.
The present invention is primarily to arrangement be present in the crankcase ventilation system check valve arrangement for solving available engine
Risk that is complicated and increasing leakage or being integrated in valve cover and covering easily makes check valve locate to influence in an environment of high temperature all the time
Itd is proposed to service life.Can be with by being equipped with the check valve formed by baffle plate and Umbrella not dipping water while closing valve in inlet manifold body
Gaseous mixture in effective control crankcase is passed through the process of inlet manifold body.Wherein, when inlet manifold body interior is in
During negative pressure condition, Umbrella not dipping water while closing valve is opened, and the gaseous mixture in crankcase is oriented to inlet manifold body by umbrella valve gear, returns to cylinder
Rekindle, when inlet manifold body interior is under barotropic condition, Umbrella not dipping water while closing valve is closed, and effectively prevents gas from entering song
In axle box system, have the function that check valve.
Compared with prior art, the present invention has advantages below：
1st, service life is grown：The present invention can protect exterior tube due to umbrella valve (check valve) is integrated in inlet manifold
The risk of road leakage, extends its service life；
2nd, it is safe and reliable：Design triton check valve avoids the risk of integrated cover lid high temperature in manifold and circumscribed is let out
The risk of dew, sealing are safer；
3rd, good seal performance：This structure just can effectively work under 10Kpa pressure differential, by crankcase gas blowby import into
In gas manifold；Sealing property is more preferable；
4th, cost is low：A plastic dam and a Umbrella not dipping water while closing valve are needed, air inlet discrimination is integrated in by ultrasonic bonding
Guan Shang, this is simple in construction, is also easy to install, and meets engine lightweight, integrated development trend.
