20160053901 | PNEUMATIC VALVE FOR VEHICLE - Disclosed is a pneumatic valve for a vehicle that includes a valve housing that has an intake hole in an intake unit at one end, an exhaust hole and a relief hole in an exhaust unit at another end, and a channel through which air flows therein. An intake plunger selectively opens and closes the intake hole by sliding in the channel of the valve housing. A relief plunger selectively opens and closes the relief hole by sliding in the channel of the valve housing. An intake coil is disposed outside the valve housing and slides the intake plunger using an electromagnetic force; and a relief coil is disposed outside the valve housing and slides the relief plunger using an electromagnetic force. | 02-25-2016 |
