WHEEL HAVING TEMPERATURE COMPENSATED AND CONTROLLED PRESSURE
摘要
<p>It is disclosed a wheel (1) having a controlled and compensated pressure comprising: a rim (2) associated with a tank (4) adapted to be filled with a fluid to a first pressure; a tyre (3) mounted on said rim and having an inner volume (3') inflated to an operating pressure, said operating pressure being lower than said first pressure; at least one valve (5) adapted to regulate a communication between said tank (4) and the inner volume (3') of said tyre (3); said valve (5) comprising at least one elastic element operatively associated with a closure member (17) designed to open and close a port (9) of said valve (5) to bring said tank (4) into communication with said tyre (3), when the pressure of said tyre (3) is lower than said operating pressure, said elastic element having an elastic constant (K) showing a variation of 10% to 40% within a temperature range included between about -50°C and about 50°C.</p>
