Abstract

L'invention concerne un amortisseur hydraulique réglable. Ledit amortisseur comporte un corps dans lequel est fixé un tube interne contenant un piston coulissant. Un diaphragme tubulaire à double effet est fixé dans le corps autour d'une extrémité du tube interne pour former un réservoir expansible relié au tube interne. Le réservoir, un passage et le tube interne sont remplis d'un fluide sous pression poussant normalement le piston dans une position initiale. Un clapet de retenue et de dosage, placé dans le passage, règle le débit du tube interne dans le réservoir, lorsqu'une charge est imposée au piston, et permet au fluide de s'écouler librement du réservoir dans le cylindre lorsque ladite charge est supprimée. Application aux amortisseurs hydrauliques réglables.
