Abstract

Le distributeur hydraulique à tiroir rotatif proportionnel « Distributeur selon l'invention » est destiné aux applications industrielles utilisant des fluides aqueuses telles eaux potables, eau industrielle, eau déminéralisée et globalement tous les fluides à faible viscosité afin d'être intégré dans tous les systèmes d'automation et de puissance hydraulique à eau impliquant des variations de grandeurs hydromécaniques proportionnelles nécessitant une pression jusqu'à 350 bar. Le distributeur proportionnel selon l'invention est spécifiquement adapté à la commande et la régulation hydraulique proportionnelle à base de fluides aqueux de faibles viscosités, dont le tiroir de distribution rotatif ne nécessite aucune lubrification et est composé d'une vis d'Archimède comportant un palier médian avec joint dynamique intégré afin d'isoler les chambres (A & B), deux paliers d'extrémités nécessaire à une parfaite rectitude du mécanisme et d'une fourrure en céramique assurant une rotation à faible frottements et des passages de fluide calibrés. Le distributeur proportionnel selon l'invention comporte un plan de pose normalisé pour montage sur embase de raccordement, les dimensions de ce composant sont en conformité avec la normalisation en vigueur. Le principe du tiroir rotatif associé à une fourrure permet un comportement diaphragmé produisant un écoulement fluidique naturellement linéaire proportionnel à la section d'ouverture, avec un faible recouvrement positif, des fuites internes négligeables, une bonne tenue dynamique et un fonctionnement sécurisé par un centrage mécanique hors tension.
