1. The gap (48) has a radius larger than the inner diameter (D¿2?)

Ledit espace (48) a un rayon supérieur au diamètre intérieur (D¿2?)

2. A rotary seal (20) capable of joining a stationary member (21) with a rotating member (22) is provided, wherein the rotary seal comprises a body (23) having a central hole (24) therethrough, wherein said central hole (24) has stepwise reducing diameter so as to form two part (25 and 26) central hole (24), wherein front part (25) of said central hole (24) has higher inner diameter and rear part (26) of said central hole (24) has lower inner diameter, wherein said front part (25) forms a seat (27) with said rear part (26) of said central hole (24), wherein said front part (25) of said central hole (24) is capable of accommodating at least one sealing member (28), and said sealing member (28) is made to sit onto said seat (27) by a screwing member (31), which when fixed onto body (23) fits into front part (25) of said central hole (24), and said rear part (26) of said central hole (24) is capable of accommodating connecting member (32) of said stationary member (21).

Selon la présente invention, un joint pour mouvement rotatif (20) permet de joindre un élément fixe (21) à un élément rotatif (22), ledit joint comprenant un corps (23) muni d'un trou central (24) qui le traverse. Le trou central (24) possède un diamètre à réduction progressive de sorte à former deux parties (25 et 26), la partie avant (25) du trou (24) ayant un diamètre intérieur et sa partie arrière (26) un diamètre intérieur inférieur. La partie avant (25) forme un siège (27) avec la partie arrière (26) du trou central (24), la partie avant (25) du trou (24) pouvant recevoir au moins un élément de scellement (28). L'élément de scellement (28) est conçu pour reposer sur le siège (27) à l'aide d'un élément de vissage (31) qui, lorsqu'il est fixé sur le corps (23), s'engage dans la partie avant (25) du trou central (24). La partie arrière (26) du trou (24) peut recevoir un élément de raccord (32) de l'élément fixe (21).
