Combination in line tire pressure measurement sensor and tire pressure safety valve

A combination comprising:

• an air line communicating with and disposed between a rotary union and a tire, the tire communicating with an axle, the rotary union axially aligned with the axle, the air line facilitates pressurized air transferred between the rotary union and a valve stem of the tire, the pressurized air inflates the tire;
• a tire pressure management safety valve disposed between the rotary union and the tire, and further disposed within the air line, the tire pressure management safety valve comprising:
• a valve housing providing a valve activation chamber;
• a fluid conduit, the fluid conduit having a downstream end and an upstream end, the fluid conduit supported by the valve housing and in fluid communication with the valve activation chamber;
• a check valve disposed within the valve activation chamber and communicating with the fluid conduit, the check valve responsive to said pressurized air within the air line, such that when said pressurized air in the air line is below a predetermined value, the check valve automatically precludes air transfer between the upstream end of the fluid conduit and the valve activation chamber;
• and
• a fitting communicating with the check valve activation chamber and the valve stem of the tire;
• and
• a tire pressure measurement sensor disposed between the valve housing and a freely rotatable airline connection, else disposed within the valve housing.
