Abstract

A.INSTALLATION POUR LA COMMANDE D'UN DISPOSITIF DE RECYCLAGE DES GAZ D'ECHAPPEMENT DANS UN MOTEUR A COMBUSTION INTERNE. B.INSTALLATION CARACTERISEE EN CE QUE LE DISPOSITIF DE REGLAGE 7 ACTIONNANT LE DISPOSITIF D'ETRANGLEMENT 5 DISPOSE DANS LA CANALISATION 4 DE RECYCLAGE DES GAZ D'ECHAPPEMENT EST ACTIONNE PAR L'INTERMEDIAIRE D'UN DISPOSITIF DE COMMUTATION 13, 14 COMMANDE PAR LE LEVIER DE REGLAGE 26 DANS LE SENS D'UNE OUVERTURE DU DISPOSITIF D'ETRANGLEMENT 5 LORSQU'UNE VALEUR LIMITE CORRESPONDANT A LA CHARGE MINIMALE EST FRANCHIE VERS LE BAS ET LORSQU'UNE VALEUR LIMITE D'UN SIGNAL DEPENDANT, AU MOINS POUR UNE CHARGE CONSTANTE, DE LA VITESSE DE ROTATION, EST ATTEINTE. C.L'INVENTION S'APPLIQUE NOTAMMENT AUX MOTEURS D'AUTOMOBILES.A.INSTALLATION FOR THE CONTROL OF AN EXHAUST GAS RECYCLING DEVICE IN AN INTERNAL COMBUSTION ENGINE. B. INSTALLATION CHARACTERIZED IN THAT THE ADJUSTMENT DEVICE 7 ACTIVATING THE THROTTLE DEVICE 5 PROVIDED IN THE EXHAUST GAS RECYCLING DUCT 4 IS ACTIVATED BY THE INTERMEDIATE OF A SWITCHING DEVICE 13, 14 CONTROLLED BY THE LEVER ADJUSTMENT 26 IN THE DIRECTION OF AN OPENING OF THE THROTTLE DEVICE 5 WHEN A LIMIT VALUE CORRESPONDING TO THE MINIMUM LOAD IS CROSSED DOWN AND WHEN A LIMIT VALUE OF A DEPENDENT SIGNAL, AT LEAST FOR A CONSTANT LOAD, OF ROTATION SPEED, IS REACHED. C. THE INVENTION APPLIES IN PARTICULAR TO AUTOMOBILE ENGINES.
