Design and simulation of two stage pressure-controlling spill-protecting breathing valve

The effect of breathing and spill-protecting of the breathing valve on the vehicle oil can have great influences on the safety of the whole vehicle. The breathing valve is studied in this article, and a new two stage pressure- controlling spill-protecting breathing valve is designed. The 3D model of the breathing valve is built in Pro/E, and the kinetics analysis of the key point of the breathing valve is done in ADAMS, which can provide theoretic guidance for designer to optimize structure design.
