Abstract: In order to be able easily to inflate a tire mounted on a rim with a seal ring (6) arranged between the two beads, without presenting the ordinary inconveniences in mounting, the inflation device is formed of a valve (V, V') provided with a locking element (2, 2') intended to be associated with a locking member (83, 51) separate from the valve. The method of inflation consists then in introducing the valve (V, V') provided with its stem (1, 1') and its locking element (2, 2') into the orifice (64) provided in the ring 6 and into the locking member (83, 51), and then turning the valve.

Abstract: The rim (1), which is intended to be equipped with a tire P of tubeless t, has a groove (11) adjacent the rim lip (10). This groove (11) is closed by an annular packing (2) having a valve (3). The valve body (32) is surrounded by a sheathing (21) of vulcanized rubber; the secant modulus of elasticity of which, under compression, is equal to at most 0.20 times the secant modulus of compression of the vulcanized rubber constituting the packing, these two moduli being measured under a relative deformation of 10%. A slot is provided in the rim for the entrance of inflation air.

Abstract: A tubeless tire valve has a one piece, integral valve body having a central passageway formed therein, wherein the passageway is formed of upper, central and lower regions. A one piece, integral valve pin has a head sized to fit in the upper region, a first shank extending away from the head to an enlargement, and a second shank extending away from the enlargement. The pin enlargement has a maximum dimension larger than the central region to create an interference fit therewith, and the maximum dimension is selected such that the enlargement can be forced through the central region. A resilient internal gasket is mounted on the second shank to seal the central passageway.

Abstract: A tire shock absorber for attachment to a pneumatic tube tire or pneumatic tubeless tire for improving the smoothness of ride and decreasing road vibrations, the tire shock absorber comprising a chamber having at least one valve means which permits the unrestricted flow of air from the tubeless tire or tube tire into the chamber when the tire is subjected to intermittent road pressure, the valve means permitting the return of the displaced air to the tubeless tire or tube tire subsequent to the tire being subjected to the intermittent pressure. The tire shock absorber is designed for positioning either exterior to the tire or interior to the tire depending upon whether or not it is a tube tire or a tubeless tire.

Abstract: A valve for vehicle tires, in particular a snap-in valve, having a shell-like plastic material of a hardness in the condition as supplied of about 65 to 75 Shore A, which has a base portion for connection to a rim or the like and a valve cylinder having an external screwthread for a valve cap, wherein an axial opening in the valve cylinder, in the axial direction, is of different diameters and accommodates a valve insert which is mounted axially displaceably against a force storage means, is to be such that manufacture and also operational reliability are improved.That is achieved in that the shell-like body is combined with the valve cylinder to provide a valve body (11) and same is produced in one piece from the plastic material in such a way that the hardness at the inside surfaces (26, 27) of the axial opening of the valve cylinder is higher, at least in the region adjoining the valve insert (12), than at the base portion (14).

Abstract: A valve for tubeless tires is of the type having elements which are radially flexible so that the elements can be deformed upon passage through a valve hole provided in a rim but which are axially rigid so as to hold the mounted valve on the rim. These elements are designed in such a manner that they cannot pass through the valve hole from the outside of the rim towards the inside under the effect of even the strongest forces. For this purpose, the lower part of these elements has, for example, a greater curvature than the curvature of the valve body.

Abstract: A tubeless tire valve has a valve body and an external annular gasket having an internal through hole. The gasket, when not mounted, has a diameter partially lower than the diameter of the cylindrical portion of the valve body, on which it will be inserted, and partially larger than the latter at the coupling area with the rim. Externally, the gasket has at one end an extended lip directed towards the rim, then an intermediate zone having a larger diameter than that of the hole in the rim, and close to the intermediate zone an annular groove of reduced diameter, while a hollowed impression is provided on the valve body at the zone where the rim will be positioned.

Abstract: A tire valve assembly which is adapted to be mounted on the rim for a tubeless tire, and wherein the tire valve assembly is constructed of a non-metallic material. The tubeless tire valve assembly includes a valve stem which is constituted of a plastic material, for example, such as nylon or fiber-reinforced nylon, or a plastic material possessing similar physical properties, which has a flange integrally formed therewith at one end of the valve stem, and which is encompassed by a rubber grommet towards that stem end, and which is adhesively bonded to the valve stem and adapted to be sealingly mounted within an aperture formed in a tire rim for a tubeless tire.

Abstract: A novel valve mechanism is disclosed which eliminates the need for a conventional cap normally associated with prior art valve and valve stem assemblies for pneumatic tires. The valve stem embodies a core with an elastomeric member to prevent ingress and egress of a fluid through the valve stem. The elastomeric member can be a normally collapsed flexible tube or a resealable septa.

Abstract: Snap-in tire valve includes rigid base larger than the rim hole opening so that the valve cannot be extruded therethrough. Valve is held in place by spring clip surrounding the valve stem.

Abstract: The periphery of the portion of the valve body of a tire valve which is located on the outside of the wheel rim is composed of elements which are elastic in transverse direction and rigid in longitudinal direction. Tightness is assured by a sealing joint. The valve body may be of a single piece or of two pieces.

Abstract: A valve for a tubeless tire which is adapted to be secured in a bore of a tire rim comprises a tubular valve body with an outer rim surface engagement flange formed on its periphery and spaced from an inner rim surface engagement flange by the length of the bore through the tire rim. At least one of the outer or inner rim surface engagement flanges is deformed into engagement with the associated tire rim surface. Preferably, a sleeve of a soft material is located around the body between these flanges and it is deformed and compressed into a groove formed by the respective flanges over each end surface of the tire rim. The construction is such that when the valve body is inserted from the exterior of the rim to the interior, the inner flange is formed by bending over the end of an internally formed sleeve which encompasses the end of a soft body or gasket and bends it into engagement with the associated inner surface of the tire rim.
