Abstract

A.UN SYSTEME DE COMMANDE D'UN FLUIDE REPONDANT A UNE CHARGE POSSEDE DES SOUPAPES DE DIRECTION ET DE COMMANDE DE L'ECOULEMENT EN REPONSE A UNE CHARGE, EN COMBINAISON AVEC UNE COMMANDE DE LA POMPE QUI REPOND A LA CHARGE LA PLUS IMPORTANTE DU SYSTEME. B.CHAQUE SOUPAPE DE COMMANDE DE LA DIRECTION EST POURVUE D'UNE COMMANDE DE LA PRESSION QUI REGLE AUTOMATIQUEMENT LA PRESSION A L'ENTREE DE LA SOUPAPE POUR MAINTENIR UN FAIBLE NIVEAU DE PRESSION CONSTANT A LA VIDANGE DU MOTEUR, ET D'UNE COMMANDE REPONDANT A UNE PRESSION NEGATIVE POUR MAINTENIR UNE DIFFERENCE DE PRESSION CONSTANTE A LA VIDANGE DU MOTEUR. LA COMMANDE REPONDANT A LA CHARGE DE CHAQUE SOUPAPE BLOQUE L'ECOULEMENT DE LA POMPE VERS LE MOTEUR QUAND LA CHARGE EST NEGATIVE. C.AVEC UNE CHARGE NEGATIVE, L'ENTREE DU MOTEUR RECOIT DU FLUIDE DE VIDANGE DU MOTEUR, CE QUI EVITE TOUTE PERTE DE PUISSANCE A LA POMPE.
