Abstract
A central tire inflation/deflation system (CTIS) with a novel valve that may deflate more quickly and may deflate to a lower pressure than the previously known central tire inflation/deflation system valves. Also, the present valve may not be temperature sensitive, at least because the present valve does not require trapped air behind a diaphragm to operate the valve. The present valve may be placed into existing CTIS's in place of existing valves, without modifying pneumatic lines of the existing CTIS's. Thus, the present valve may be operated by a single fluid flow line, receive pressure from the single fluid flow line, and exhaust to the single fluid flow line. A second communication line, either a pneumatic pilot line or an electrical line, is not necessary, which allows the present valve to be retrofit into an existing CTIS without adding weight or complication from additional components.
