The risk that portion's pipeline is revealed, extends its service life；
2nd, it is safe and reliable：Design that triton check valve avoids the risk of integrated cover lid high temperature and circumscribed is let out in the manifold
The risk of dew, seals safer；
3rd, good seal performance：This structure just effectively can work under the pressure differential of 10Kpa, by crankcase gas blowby import into
In gas manifold；Sealing property is more preferable；
4th, low cost：A plastic dam and a Umbrella not dipping water while closing valve is needed, air inlet discrimination is integrated in by ultrasonic bonding
Guan Shang, this simple structure are also easy to install, meet engine lightweight, integrated development trend.
