A pneumatic in-line skating wheel having a tire body (4) and central hub (6) chemically bonded during a polyurethane casting process and further including an annularly encapsulated air bladder (8) centrally spaced within the tire body (4) to provide shock absorption. The bladder (8) in one embodiment is in communication with a valve (10) for inflation and deflation thereof such that the overall tire resiliency may be adjusted, enabling adjustable performance characteristics of the wheel. One embodiment of the valve incorporates a resilient core within a rigid barrel and stretchable to allow an inflation needle to stretch the core and drive a poppet off a seat at the interior end of the barrel.

Cette invention concerne une roue pneumatique montée en ligne pour patins à roulettes, comprenant un corps pneumatique (4) ainsi qu'un moyeu central (6) chimiquement lié lors d'un procédé de moulage de polyuréthanne. Cette roue comprend également une chambre à air (8) placée en position annulaire au centre du corps pneumatique (4) de manière à absorber les chocs. Dans un mode de réalisation, la chambre (8) est en contact avec une valve (10) permettant de la gonfler ou de la dégonfler, afin que l'on puisse ajuster l'élasticité du pneu tout entier ainsi que des critères de performance de la roue. Dans un mode de réalisation, la valve se compose d'un fût rigide contenant un noyau élastique pouvant être étiré à l'aide d'une aiguille de gonflage de manière à faire sortir un clapet hors de son siège au fond dudit fût.
