During the modification of the suspension system, the hard pneumatic butterfly valve should be matched with the hard ball valve, and the hardness of the ball valve is closely related to the vehicle weight, so the heavier vehicles generally use the hard pneumatic butterfly valve
The device connected to the shock inducing crankshaft is used to counter the torsional vibration of the crankshaft. The structure of the pneumatic butterfly valve is that the piston rod with a piston is inserted into the cylinder to flush oil into the barrel
There is an orifice on the piston, so that the oil in the two spaces separated by the piston can supplement each other
