Abstract

POMPE OU MOTEUR A ENGRENAGE HELICOIDAL EN PRISE INTERIEUREMENT, OU UNE TIGE DE COMMANDE EST RELIEE POUR ENTRAINEMENT A L'ORGANE INTERIEUR OU EXTERIEUR POUR EFFECTUER UN MOUVEMENT A LA FOIS ROTATIF ET ORBITAL DANS UNE CHAMBRE D'ENTREE OU DE SORTIE DE LA POMPE OU DU MOTEUR. UNE DOUILLE RIGIDE FIXE S'ETEND DANS LADITE CHAMBRE ET ENTOURE LA PLUS GRANDE PARTIE DE LA LONGUEUR DE LA TIGE DE COMMANDE A L'INTERIEUR DE LA CHAMBRE AU TRAVERS DE LAQUELLE ELLE PASSE. L'INVENTION INTERESSE EN PREMIER LIEU LES INDUSTRIES MECANIQUES.PUMP OR MOTOR WITH HELICOIDAL GEAR IN INTERNAL TAKE-UP, OR A CONTROL ROD IS CONNECTED FOR DRIVING TO THE INTERNAL OR EXTERIOR BODY TO PERFORM A MOVEMENT BOTH ROTARY AND ORBITAL IN AN INLET OR OUTLET CHAMBER OF THE PUMP OR OF THE ENGINE. A FIXED RIGID SOCKET EXTENDS THROUGH THE SAID CHAMBER AND SURROUND THE LARGEST PART OF THE LENGTH OF THE CONTROL ROD INSIDE THE CHAMBER THROUGH WHICH IT PASSES. THE INVENTION FIRST INTERESTED IN MECHANICAL INDUSTRIES.
