Abstract

LA MACHINE A PISTONS ROTATIFS COMPREND UN ROTOR 4 MUNI D'UN CERTAIN NOMBRE DE PISTONS 5 QUI S'APPUIENT DE LEUR SURFACE CONTRE UNE PAROI INTERNE D'UN STATOR 6. LA PAROI INTERNE DU STATOR 6 PRESENTE DES CAMES NEGATIVES 21 QUI DETERMINENT UN MOUVEMENT CONTROLE DU PISTON 5 VERS L'EXTERIEUR EN DIRECTION RADIALE ET UN RETOUR DU PISTON 5 VERS SA POSITION DE DEPART. LA PENTE DE LA CAME EST NULLE A LA POSITION RADIALE LA PLUS EXTERIEURE DU PISTON 5. DANS LA PARTIE ASCENDANTE DE LA CAME 21, L'INTERVALLE ANGULAIRE AU COURS DUQUEL LA PENTE AUGMENTE EST PLUS GRAND QUE L'INTERVALLE ANGULAIRE AU COURS DUQUEL LA PENTE DIMINUE. UTILISATION EN PARTICULIER COMME MOTEUR OU POMPE HYDRAULIQUE.THE ROTARY PISTON MACHINE INCLUDES A ROTOR 4 EQUIPPED WITH A NUMBER OF PISTONS 5 WHICH BEEN ON THEIR SURFACE AGAINST AN INTERNAL WALL OF A STATOR 6. THE INTERNAL WALL OF STATOR 6 SHOWS NEGATIVE CAMS 21 WHICH DETERMINE MOVEMENT CHECKING PISTON 5 OUTSIDE IN A RADIAL DIRECTION AND RETURNING PISTON 5 TO ITS STARTING POSITION. THE SLOPE OF THE CAM IS ZERO AT THE EXTERIOR RADIAL POSITION OF THE PISTON 5.IN THE ASCENDING PORTION OF THE CAM 21, THE ANGULAR INTERVAL DURING WHICH THE SLOPE INCREASES IS GREATER THAN THE ANGULAR INTERVAL DURING THE SLOPE DECREASES. USE IN PARTICULAR AS A MOTOR OR HYDRAULIC PUMP.
