VALVE DEVICE FOR PNEUMATIC TYRE INCLUDING PRESSURE SENSOR
First Claim
1. A valve device for a pneumatic tyre having an upper and lower desired inflation pressure, said valve device including:
- a main body having an inlet port sealingly engageable with a compressed air supply and an outlet port sealingly engageable with said pneumatic tyre;
at least one pressure sensor for sensing the pressure in said pneumatic tyre;
a microprocessor disposed in a lower portion of said main body; and
at least one lamp operatively associated with said at least one pressure sensor and said microprocessor such that upon said pressure in said pneumatic tyre being substantially above or below said upper or lower desired inflation pressures respectively, said microprocessor instructs said at least one lamp to illuminate.

Abstract
A valve device (10) for a pneumatic tyre (12) having an upper and lower desired inflation pressure. The valve device includes a main body (16) having an inlet port (18) adapted for sealed engagement with a compressed air supply (20) and an outlet port (22) adapted for sealed engagement with the pneumatic tyre. At least one pressure sensor (24) for sensing the pressure in the pneumatic tyre and an electrical indicating means operatively associated with the at least one pressure sensor is also provided for indicating to a user when the pressure in the pneumatic tyre is below the lower desired inflation pressure or above the upper desired inflation pressure.
