Abstract

The invention relates to a wheel valve (1) for the tyre of a vehicle, comprising a non-return valve (11), two half-bodies (3,4) defining a cavity and assembled with a membrane (6) inserted therebetween acting as a sealing joint between said half-bodies, said non-return valve comprising a tubular element (12) which is connected to the membrane and inside which the closing element (18) can move between a seat (17) and a base (20), said closing element being applied against the seat by means of the pressure prevailing in the tyre. The closing element (18) is subjected to the action of a magnetic field ensuring the maintainance thereof at the base (20) so that the valve can be kept open and that the tyre can deflate slowly. It is made of a steel ball (18) which cooperates with the seat (17) and which is defined by a ring (1) which is inserted into the tubular element (12). The magnetic field is produced with the aid of a magnetized element (22) disposed in the vicinity of the membrane (6).
