Abstract
Dispositif hydraulique d'assistance. Un servomoteur hydraulique comporte une chambre de pression normalement alimentée en fluide sous pression en réponse à l'actionnement d'une valve à tiroir par des moyens de commande du type à levier situés dans la chambre de pression et contrôlés par un opérateur. Un premier accumulateur est monté sur le boîtier du servomoteur et la communication du fluide entre le premier accumulateur et la chambre de pression est contrôlée par une valve mise en oeuvre par un organe annulaire monté sur le tiroir et sollicitée par les moyens de commande. Un deuxième accumulateur monté sur un support autre que le boîtier du servomoteur est relié à la chambre de pression par un conduit externe au boîtier, et une autre valve, également mise en oeuvre par l'organe annulaire.
