Abstract

Ce vérin est du type de ceux servant à l'exécution d'un mouvement rectiligne et comprenant au moins une paroi de révolution extensible en accordéon et des éléments de fermeture rigides aux deux extrémités axiales de ladite paroi, le fluide sous pression étant amené à l'un des éléments de fermeture, qui est immobilisé, tandis que l'autre élément de fermeture exécute le mouvement rectiligne. Dans le vérin selon l'invention, les éléments de fermeture 12, 13, ont, vus en coupe longitudinale, un profil en U qui coiffe la paroi en accordéon 14, sont orientés en sens inverse l'un de l'autre et se chevauchent l'un l'autre pour un guidage axial, avec immobilisation en rotation, pendant l'exécution du mouvement rectiligne. Ce guidage simple et sûr réduit considérablement le coût de fabrication du vérin.
