ABSTRACT:
A tire valve is disclosed which includes an automatic pressure releasing device and comprises an inlet assembly and an outlet assembly. The inlet assembly includes a valve pole biased closed by a spring to allow air input. The valve includes an inlet/outlet assembly which has an inlet valve room and a pressure release room. These rooms utilize ball valves and springs to control the air flow. A pressure releasing device is provided and comprises an adjusting screw, a spring and a ball valve. The pressure releasing device will function when the tire air pressure exceeds a specified range, so as to ensure proper air pressure in the tire.
