Abstract
MACHINE HYDRAULIQUE A PISTONS ROTATIFS. ELLE COMPORTE UNE COURONNE A DENTURE INTERIEURE DANS LAQUELLE TOURNE EXCENTRIQUEMENT UNE COURONNE A DENTURE EXTERIEURE AYANT UN NOMBRE DE DENTS INFERIEUR A CELUI DE LA COURONNE EXTERIEURE. LES ENTRE-DENTS DE CETTE COURONNE EXTERIEURE SONT PROLONGES RADIALEMENT VERS L'EXTERIEUR ET LES QUEUES DES VIS DESTINEES A FIXER LA MACHINE AU CORPS CONTENANT LE OU LES TIROIRS DE COMMANDE PASSENT DANS CES PROLONGEMENTS, EN MENAGEANT AUTOUR D'ELLES DES INTERSTICES PERMETTANT AU LIQUIDE DE CIRCULER DANS UN SENS OU DANS L'AUTRE ENTRE LES CHAMBRES DE REFOULEMENT ET LE TIROIR. APPLICATION NOTAMMENT AUX DIRECTIONS HYDROSTATIQUES POUR AUTOMOBILES.
