Abstract

MECANISME REGULATEUR POUR LE MAINTIEN A VALEUR CONSTANTE DE LA VITESSE DE RALENTI DU MOTEUR D'UN VEHICULE EN FONCTION DE LA CHARGE DE CE MOTEUR, TELLE QUE LA MESURE LE NIVEAU DU VIDE REGNANT DANS SON COLLECTEUR D'ASPIRATION. POUR GARANTIR QUE LE POUSSOIR 18 QUI ACTIONNE LE PAPILLON DU CARBURATEUR NE REAGISSE QU'A LA SEULE DIFFERENCE ENTRE LA PRESSION ATMOSPHERIQUE ET LE NIVEAU DE VIDE DANS LE COLLECTEUR D'ASPIRATION, L'INVENTION PREVOIT UN PREMIER PISTON 24 QUI DEPLACE CE POUSSOIR EN FONCTION DES VARIATIONS DE LADITE DIFFERENCE DE PRESSION AINSI QUE DES MOYENS FORMANT VALVE 80, 94 QUI CONTROLENT LA COMMUNICATION DU FLUIDE A TRAVERS LEDIT PISTON EN FONCTION DES DEPLACEMENTS RELATIFS D'UN SECOND PISTON 22 EGALEMENT SOUMIS A CETTE MEME DIFFERENCE DE PRESSION. APPLICATION A L'EQUIPEMENT DES VEHICULES AUTOMOBILES.REGULATORY MECHANISM FOR MAINTAINING A CONSTANT VALUE OF THE IDLE SPEED OF THE ENGINE OF A VEHICLE AS A FUNCTION OF THE LOAD OF THIS ENGINE, SUCH AS MEASURING THE LEVEL OF THE VACUUM IN ITS SUCTION MANIFOLD. TO ENSURE THAT THE TAPPET 18 WHICH ACTIVATES THE THROTTLE OF THE CARBURETOR ACTS ONLY TO THE DIFFERENCE BETWEEN THE ATMOSPHERIC PRESSURE AND THE VACUUM LEVEL IN THE SUCTION MANIFOLD, THE INVENTION PROVIDES A FIRST PISTON 24 WHICH MOVES THIS TAPPET IN OPERATION VARIATIONS OF THE SAID PRESSURE DIFFERENCE AS WELL AS MEANS FORMING VALVE 80, 94 WHICH CONTROL THE COMMUNICATION OF THE FLUID THROUGH THIS PISTON AS A FUNCTION OF THE RELATIVE MOVEMENTS OF A SECOND PISTON 22 ALSO SUBJECT TO THIS SAME PRESSURE DIFFERENCE. APPLICATION TO MOTOR VEHICLE EQUIPMENT.
