Patent ID: 8490479

Claim:
A valve ( 30 ) for inflating tires ( 10 ) associable with a transducer ( 40 ) provided with electronic sensors for detection and transmission of certain operating parameters of the tire ( 10 ), wherein the valve is arranged for being mounted on a rim ( 20 ) of a wheel for vehicles so that the valve ( 30 ) projects outside the rim ( 20 ) and the transducer ( 40 ) is positioned within a chamber ( 50 ) delimited by the tire ( 10 ) and by the rim ( 20 ), said valve ( 30 ) comprising: means for signaling ( 70 , 80 ) that, once the valve has been mounted, are visible from the outside of the wheel, wherein said means for signaling are correlated univocally with the orientation of the transducer ( 40 ), and are arranged for indicating the position assumed by the transducer inside said chamber ( 50 ).
