ABSTRACT:
An excess tire air pressure relief valve positioned on an automobile tire for relieving the pressure within the tire caused by heat or over inflation. The valve has a main tube that extends through the tire rim, to selectively communicate air from the tire interior to the tire exterior. The tube has a spring that extends between a pair of disks. A seal is positioned below the spring support disk and is pressed against a lower lip by the spring to prevent air leakage through the tube. The spring is selected to exert sufficient force against the seal to prevent air leakage through the main tube. When internal pressure is greater than normal within the tire, the spring is urged outward, allowing air to escape around the edges of the spring support disk until the internal pressure lowers such that the spring can once again hold the seal tightly against the bottom lip.
