Title
(EN) WHEEL HAVING TEMPERATURE COMPENSATED AND CONTROLLED PRESSURE
(FR) ROUE A COMPENSATION DE TEMPERATURE ET REGULATION DE PRESSION
Abstract
(EN)
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 tnak (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 tnak (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.
(FR)
L'invention porte sur une roue (1) à compensation de température et régulation de pression comportant: une jante (2) associée à un réservoir (4) rempli d'un fluide à une première pression; un pneumatique (3) monté sur ladite jante et présentant un volume intérieur (3') gonflé à une pression de fonctionnement inférieure à ladite première pression; et au moins une soupape (5) régulant les communications entre le réservoir (4) et le volume intérieur (3') du pneumatique (3). Ladite soupape (5) comporte au moins un élément élastique fonctionnellement associé à un obturateur (17) ouvrant ou fermant un orifice (9) de la soupape pour mettre le réservoir (4) en communication avec le pneumatique (3) lorsque sa pression est inférieure à la pression de fonctionnement. Ledit élément élastique présente une constante d'élasticité (K) variant de 10 % à 40 % lorsque la température varie entre environ -50 °C et environ 50 °C.
