Device for monitoring maintenance and adjustment of pressure in a tire

The apparatus of clam, 1, said end being deformable so as to have a cross-sectional area greater than zero, having a minimum volume which is 1% to 80% of maximum volume of the chamber.

The apparatus of monitoring, maintaining and adjustment of pressure comprising:

• a tire having an interior space and a wall, said tire being suitable for receiving external mechanical forces when rolling on a road surface;
• a chamber having a shape memory, said chamber being deformable during the receiving of the external mechanical forces, said chamber having a lengthwise shape at least partially copying a shape of said tire, said chamber being connected with said interior space of said tire and an outside environment, at least one wall of said chamber being either adjacent to said wall of said tire or being part of said wall of said tire, at least a portion of said chamber being deformable up to a zero cross section, said chamber having a block with shape memory, said chamber being freely open at one end to an interior space of said tire and having at least one external valve at or adjacent to an opposite end, said at least one external valve connecting said chamber to said outside environment.
