ABSTRACT:
A valve assembly having a pair of flow passages in fluid communication with a chamber leading to a tire. One of the passages contains a typical one-way valve core mechanism while the other passage contains a pressure release mechanism. The cross sectional area of the tire inflation passage is less than the cross sectional area of the passage leading from the chamber to the pressure release bore. The exhaust port has a closure means which opens simultaneously with the pressure release mechanism. The closure means offers resistance to escaping inflation fluid which serves to urge the pressure release mechanism open against the biasing force of spring means urging it closed.
