Problems solved by technology

When the tire is removed, since there is no sensor positioning reference inside the air chamber, even the experienced hands of the technician in the department may still cause the edge of the tire to hit the sensor, thus causing irreversible damage to the sensor
[0010] Clip-in valves with metal fixtures are stronger and experience less rotation due to centripetal push, but may in any case be susceptible to damage from the nuts used to secure the valve-sensor assembly to the rim when they end up tightening. During the process, undue application of force causes the entire valve-sensor assembly to rotate, thereby risking the sensor from its seat, which may thus incur the above-mentioned risks during tire changes

Embodiment Construction

[0032] refer to figure 1 , shows a wheel rim 20 of a motor vehicle according to known technology, on which are mounted a valve 30 and a sensor 40 assembled together to form a valve-sensor assembly for a TPMS system.

[0033] figure 2 shown figure 1 Sectional view of the same rim 20 , again according to the prior art, on which is mounted a tire 10 defining a compartment 50 in which is located a sensor 40 combined with a valve 30 for a TPMS system.

[0034] It is evident from the figures that a part of the valve 30 itself always protrudes outside the rim 20 and is therefore visible when the tire 10 is mounted and inflated.

[0035] refer to image 3 , shows a valve-sensor assembly according to the first aspect of the invention.

[0036] The valve 30 having a cylindrical shape is of the "snap-on" type, i.e. partly covered by a ring of rubber material 60 which acts as a Gasket.

[0037] The rubber covering part 60 is provided with marking means 70, constituted for example b...

Abstract

A valve (30) for inflating tyres (10) of tyred wheels associable with a transducer (40) provided with electronic sensors for detection and transmission of certain operating parameters of the tyre (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 tyre (10) and by the rim (20), said valve (30) comprising signalling means (70, 80) which, once the valve has been mounted, are visible from the outside of the wheel, where said signalling means are correlated univocally with the orientation of the transducer, and are arranged for indicating the position assumed by the transducer inside said chamber.

Description

technical field [0001] This invention relates to valves for inflating the tires of tire wheels, and more particularly to tires for vehicles, where the term "vehicle" means a motor vehicle, a pickup, a motorcycle, or more generally a valve on a tire mobile device. [0002] In more detail, the invention relates to a valve designed for use in the context of TPMS (Tire Pressure Monitoring System) technology, where electronic sensors for detecting and transmitting some operating parameters of the tire are mounted directly on the valve itself, and the valve is formed by forming A hole in the rim is fixed to the wheel, the operating parameters being in particular pressure, and eg temperature. Background technique [0003] The valves used in the context of TPMS devices are the usual clip-on or snap-on valves, ie the type that is bonded to the rim by threaded or elastic clip-on arrangements. [0004] This structure of the valve is combined with a sensor powered by a battery, which ...
