Abstract

L'invention concerne un régulateur de débit, notamment pour la commande du mécanisme de levage d'un chariot de manutention. Le régulateur assure un effet d'amortissement analogue à celui d'un orifice fixe, tout en assurant simultanément cet effet à une vitesse constante, de manière à maintenir le débit malgré des changements de la charge. Le régulateur comporte un stabilisateur de débit associé à un orifice détecteur pour améliorer la réaction du régulateur de débit aux changements de pression. Le régulateur comporte en outre des amortisseurs destinés à amortir le mouvement du piston tant vers l'intérieur que vers l'extérieur pendant son fonctionnement Application à la commande du- mécanisme de levage d'un chariot de manutention.
