Abstract

Vérin de serrage hydraulique pour établir et/ou maintenir un serrage, dont une tige de piston (2) comporte un piston de serrage (12) ayant une surface de piston de serrage (24). Le serrage est maintenu par un ressort de serrage (10), qui exerce une force de serrage sur la surface de piston de serrage (24). Le vérin comporte plusieurs tiges de piston (2, 4) entre lesquelles il y a chaque fois un ressort de serrage (6).
