Abstract
A valve assembly for a tire pressure management system includes a housing. A first chamber () is provided in the housing. A second chamber () is provided in the housing. The second chamber is selectively in fluid communication with the first chamber. A third chamber () is provided in the housing. The third chamber is selectively in fluid communication with the second chamber. A deflate piston () is at least partially provided in the third chamber and the second chamber. The deflate piston () selectively permits or prevents fluid communication between the second chamber and the third chamber. An inflate piston () is attached to the deflate piston (). The inflate piston () is at least partially provided in the second chamber and the first chamber. The inflate piston () selectively permits or prevents fluid communication between the first chamber and the second chamber. At a first pressure, the second chamber is in direct fluid communication with the first chamber and, at a second pressure, the second chamber is in direct fluid communication with the third chamber. The second pressure is greater than the first pressure and the first pressure is greater than an initial pressure.
