Abstract
A device for transport of air in the tire P or close to it consisting of a chamber K in the shape of a hollow compressible channel, placed along at least a part of the tire perimeter, characterized by the fact that a ring OK is placed at the inner side of the chamber K with the distance of its outer side from the tire axis of rotation equal to 1 to 1.1 multiple of the distance of the bottom side of the chamber K from the axis of rotation of the tire P.
Claims11
A device for transport of air for a tire, comprising
- a component that at least partially defines a chamber, the component being adapted to be placed along at least a part of a perimeter of the tire,
- a ring disposed radially inwardly of a radially inner side of the component, wherein a radial distance between the radially inner side of the component and an axis of rotation of the tire is equal to 1 to 1.1 times a radial distance between a radially outer side of the ring at lateral edges of the ring at radially outermost parts of the ring and the axis of rotation of the tire;
- and
- a structure distinct from the tire, the structure defining an inner reservoir adapted to be at least partially disposed between the ring and the tire, wherein the component is disposed outside of the inner reservoir, and wherein an exterior surface of the structure is in contact with an inner surface of the ring.

A tire rim comprising a device for transport of air for a tire, the device comprising
- a component that at least partially defines a chamber, the component being adapted to be placed along at least a part of a perimeter of the tire when the tire is mounted on the rim, and
- a ring disposed radially inwardly of a radially inner side of the component, wherein a radial distance between the radially inner side of the component and an axis of rotation of the rim is equal to 1 to 1.1 times a radial distance between a radially outer side of the ring at lateral edges of the ring at radially outermost parts of the ring and the axis of rotation of the rim;
- and
- a structure distinct from the tire, the structure defining an inner reservoir adapted to be at least partially disposed between the ring and the tire, wherein the component is disposed outside of the inner reservoir, and wherein an exterior surface of the structure is in contact with an inner surface of the ring.
