Abstract
L'invention concerne un cylindre dans le corps duquel est disposé un piston coulissant axialement et muni d'un joint d'étanchéité. Le cylindre est caractérisé par le fait que le joint d'étanchéité comporte un anneau 2 formé d'un matériau dont l'allongement élastique est au moins égal à celui du matériau du corps de cylindre 1 et en ce que des forces de compression agissent sur l'anneau 2 dans une direction axiale et une direction radiale. Application à des cylindres pour hautes pressions.
