Abstract

Système hydraulique (15) comprenant un accumulateur (32) dans lequel un piston (28) coulissant délimite une chambre (22) dite 'chambre sous pression' et peut être sollicité afin de mettre sous pression un fluide hydraulique contenu dans ladite chambre, et un réservoir (36) de volume variable. Le système comporte en outre un bras (40) qui, lorsque le piston est sollicité et évacue du fluide hors de la chambre sous pression, est actionné conjointement avec le piston et déplace une paroi mobile du réservoir, entraînant ainsi une augmentation de volume du réservoir sensiblement égale à la diminution de volume de la chambre sous pression. Le système est agencé de telle sorte que le réservoir est apte à recevoir le fluide évacué provenant de la chambre sous pression, le système comportant en outre des moyens de maintien (35,39) pour maintenir la pression dans le réservoir sensiblement à la pression atmosphérique.
