Abstract

A.DISPOSITIF PERMETTANT D'AVOIR DES COURSES VARIABLES QUI PEUVENT ALLER DU NEUTRE AU MAXIMUM SANS INTERVENIR SUR LA VITESSE DE ROTATION DU VILEBREQUIN. B.IL COMPREND, UN VILEBREQUIN 8 QUI A SUR LA PARTIE EXCENTRIQUE DU PLUS PETIT DIAMETRE 34 UNE BAGUE EXCENTRIQUE 7 QUI EST LIEE AU CORPS DU DISPOSITIF 33. LE DISPOSITIF (CARTER COUVERCLE) PLACE SUR LA PARTIE EXCENTRIQUE DE GROS DIAMETRE 35 DU VILEBREQUIN 8 EST CONSTITUE D'UN CARTER 33 ET D'UN COUVERCLE 22 QUI RENFERMENT A EUX DEUX, DEUX CHAMBRES 27 ET 28 SEPAREES PAR DEUX CLOISONS 31 ET 32 PARALLELES AU VILEBREQUIN. QUAND L'UNE DES DEUX CHAMBRES DIMINUE L'AUTRE AUGMENTE (OU LE CONTRAIRE) PAR LA PRESSION D'HUILE PROVENANT D'UNE AUTRE POMPE. CE PROCESSUS EST L'AUTEUR DE LA ROTATION D'UN DEMI-TOUR DE LA BAGUE EXCENTRIQUE 7 SUR LE VILEBREQUIN 8 ET DU FAIT QUE CES DEUX ELEMENTS PEUVENT AVOIR UN CENTRE DE GRAVITE DIFFERENT. C.L'APPLICATION EST POSSIBLE POUR LES POMPES A PISTONS PERPENDICULAIRES AU VILEBREQUIN AVEC OU SANS BIELLES ET A TOUS LES VARIATEURS DE COURS DE PRESSION DE TOUS GENRES A DES VITESSES DIFFERENTES.
