Abstract
A tire pressure indicating apparatus has a plurality of interconnected concentric cylindrical parts including, a base, a flexible diaphragm providing an annular U-shaped wall, a valve body, an indicator sleeve, a cover and a spring, the spring compressively engaged between the cover and the indicator sleeve, such that a pressure differential across the diaphragm acts in opposition to the spring to move the indicator sleeve axially so as to display a colored surface of the sleeve through a window in the cover, or an alternate color uncovered by sleeve movement.
