Abstract

MACHINE HYDRAULIQUE A PISTON ROTATIF COMPORTANT UN CARTER1, UNE DOUILLE7 LIEE A L'ARBRE PRINCIPAL8 ET, PAR UN ARBRE ARTICULE9, A UN ROTOR10 DENTE QUI, AVEC LE STATOR3 EN FORME DE COURONNE DENTEE, DEFINIT LES CHAMBRES A VOLUME VARIABLE. LADITE DOUILLE JOUE LE ROLE DE TIROIR ROTATIF ET EST RELIEE D'UNE PART AU PALIER AXIAL14 PAR AU MOINS UN PERCAGE40 ET D'AUTRE PART A DEUX CANAUX DONT L'UN20 ADMET LE FLUIDE A HAUTE PRESSION ET DONT L'AUTRE EVACUE LE FUIDE A BASSE PRESSION. AFIN D'EVITER QUE LA GARNITURE D'ETANCHEITE17 NE SUBISSE DE SOLLICITATIONS TROP FORTES ET NE COINCE L'ARBRE PRINCIPAL, IL EST PREVU DEUX SOUPAPES DE RETENUE38 QUI SONT MONTEES ENTRE L'ESPACE INTERIEUR11 DE LA DOUILLE ET CHACUN DES DEUX CANAUX, L'UNE DE CES SOUPAPES S'OUVRANT SI LA PRESSION DANS L'ESPACE INTERIEUR11 DEPASSE CELLE QUI REGNE DANS LE CANAL CORRESPONDANT.
