Abstract

L'invention concerne un cylindre de travail vissable actionné par un fluide de pression avec éléments de fermeture pour accouplement du tube cylindrique. L'invention vise à mettre au point un cylindre de travail vissable actionné par un fluide de pression, qui reste étanche dans la plage des hautes pressions, même dans des atmosphères agressives, peut être fabriqué de façon économique, est facile à produire grâce à l'utilisation la plus grande possible de techniques sans enlèvement de copeaux et présente ainsi les avantages qui en découlent. A cet effet, l'étanchéité est obtenue par compression de la surface d'étanchéité (10) de l'élément de fermeture de guidage, de la surface d'étanchéité (11) de l'élément de fermeture du fond, de la surface d'étanchéité (12) du tube cylindrique et de la surface d'étanchéité (22) de la gaine du tube intérieur. Toutes ces surfaces qui sont élastiques et de forme correspondante sont situées sur les éléments intervenant dans le vissage, à savoir l'élément de fermeture de guidage (2), l'élément de fermeture du fond (3) et le tube cylindrique (4) qui sont fabriqués sans enlèvement de copeaux, à proximité des surfaces d'étanchéité (10; 11; 12; 22), par laminage du filetage et des biseaux d'étanchéité sur les éléments comprimés, et qui présentent de préférence une inclinaison comprise entre 6 et 12°. La compression des éléments à l'intérieur de la zone élastique est si importante que des décalages dans le sens axial et radial, dus aux pressions de service, se produisent dans la zone élastique. Le module d'élasticité des matériaux des surfaces d'étanchéité (10; 11; 12; 22) qui coopèrent l'une avec l'autre, à l'intérieur de la plage de température comprise entre 0 et 200 °C, est de l'ordre de 60 à 250 x 103 N/mm2 ± 10 % et la contrainte limite est donnée par la limite d'élasticité respective des matériaux employés entre 200 N/mm2 et 1050 N/mm2.
