Abstract

Le capteur de débit de fluide comprend un tiroir creux 58 déplaçable sur un axe 66 contre un ressort 68 et portant un cordon périphérique 80 qui coopère avec la paroi 61 d'un col 60 pour former un chemin d'écoulement annulaire entre deux chambres 92 et 90 d'une enveloppe 28 quand le tiroir se déplace sous l'action de la différence de pression de fluide entre les chambres 92 et 90 qui est utilisée comme mesure du débit à travers le capteur. Dans la position de repos représentée du tiroir 58, le cordon périphérique 80 repose contre un siège de vanne 57 et un chemin de passage résiduel entre les chambres est établi par un petit orifice de fuide 89 dans la paroi du tiroir. Le capteur de débit s'applique à la commande de vérins hydrauliques.
