Abstract: A fixing element (470) that enables an electronic unit (440) to be fixed on the inside of a tire-wheel assembly, on the tubular insert (433) of an inflation valve (430) of the tire-wheel assembly, the fixing element comprising: an interface piece (471) comprising means to establish a connection with the tubular insert of the valve and a housing (488) for a seal (460); at least one container (473) holding or designed to hold the electronic unit; and at least one attachment piece (472) that enables elastic coupling between the interface piece and the container. A method for mounting an electronic unit (440) on a tire-wheel assembly is also disclosed.

Abstract: Inflation valve having a tube and designed for use in an assembly consisting of a tire and a wheel, the valve having: (i) snap-in mechanism that enable the valve to be fixed in a cylindrical hole of circular cross-section formed in a rim of the wheel; (ii) mechanism suitable for receiving a torque intended to rotate the valve in the hole; (iii) an attachment piece provided with a mechanism for attaching the valve to a unit designed to be fitted inside the tire; the mechanism the valve to be attached to the unit being such that the attachment piece is separated from the unit when the valve is rotated in the hole in a predetermined rotation direction.

Abstract: Inflation valve (230; 330) comprising a tube (33) and designed for use in an assembly consisting of a tire (10) and a wheel (20), the valve comprising: (i) snap-in means (35, 36) that enable the valve to be fixed in a cylindrical hole of circular cross-section formed in a rim (21) of the wheel; (ii) means suitable for receiving a torque intended to rotate the valve in the hole; (iii) an attachment piece (237; 337) provided with means for attaching the valve to a unit (40) designed to be fitted inside the tire; the means enabling the valve to be attached to the unit being such that the attachment piece is separated from the unit when the valve is rotated in the hole in a predetermined rotation direction.

Abstract: Inflation valve (330; 430) configured for use in a tyre (10)—wheel (20)—assembly, the wheel comprising a mounting rim for the tyre provided with a valve hole of diameter DT, the valve comprising: (i) a deformable valve base (335; 435) designed to fix the valve in the said valve hole in a leakproof manner, the valve base being provided with a peripheral groove (36) of diameter DR, DR being larger than DT, and of width E, designed to fit over the edge (21) of the valve hole; (ii) a rigid, rectilinear tube (33) of circular cross-section, a first end of which is configured to remain outside the tyre and a second end of which is provided with means to enable connection with a unit (40) configured to be fitted inside the tyre, the tube passing through the valve base and extending on either side of the valve base, the inflation valve comprising in the part thereof located between a first plane (71) which is perpendicular to the axis of the tube and intersects the said peripheral groove half-way along, and a second p

Abstract: A valve for removable attachment to the rim of a heavy-vehicle tubeless t includes a valve base, a locking nut and a sealing joint. The valve base has a tubulure that passes through an opening in the rim, a shoulder for compressing the sealing joint against one surface of the rim and two diametrically opposite resting surfaces for engaging the rim surface and limiting the compression of the sealing joint. The locking nut cooperates with the opposite surface of the rim to compress the sealing joint against the rim.
