Cámara de neumático

Cámara de neumático (30, 130) tórica que tiene la forma de un tubo (40, 140) anillado flexible curvado y cerrado sobre sí mismo, comprendiendo el tubo una alternancia de anillos en cordón (46, 146) y de anillos en canal (48, 148), presentando el tubo un radio (R), caracterizada por que, considerado en un plano perpendicular al eje (A) del tubo, el grosor radial (54, 154') de los anillos en cordón (46, 146) es inferior al grosor radial (56, 156') de los anillos en canal (48, 148). The invention relates to a toroidal inner tube (30, 130). The invention is characterized by the fact that the inner tube (30, 130) is in the form of a flexible corrugated tube (40, 140) that is curved to form a closed loop, the tube comprising alternating crest rings (46, 146) and trough rings (48, 148), the tube presenting a radius (R) and, when measured in a plane perpendicular to the axis of the tube, the radial thickness of at least one of the crest rings is less than the radial thickness of at least one of the trough rings (48, 148).
