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.
