Abstract

LA PRESENTE INVENTION CONCERNE UNE POMPE HYDRAULIQUE DU TYPE A BARILLET A DISTRIBUTION VARIABLE. LA POMPE COMPORTE UN BARILLET 1 DANS LEQUEL SONT REALISES DES CYLINDRES 2 D'AXES PARALLELES A L'AXE DU BARILLET, LES BIELLES 11 DES PISTONS10 ETANT ARTICULEES SUR UN PLATEAU13 DONT L'AXE FAIT, AVEC L'AXE DU BARILLET QUI SE TROUVE DANS UN MEME PLAN, UN ANGLE VARIABLE B, LA COURSE DES PISTONS ETANT D'AUTANT PLUS GRANDE QUE L'ANGLE B EST PLUS GRAND ET ETANT PROPORTIONNELLE AU SINUS DE CET ANGLE, ET UN BLOC DISTRIBUTEUR3 PRESENTANT DANS SA GLACE DEUX LUMIERES EN ARC DE CERCLE8, L'UNE BASSE PRESSION, L'AUTRE HAUTE PRESSION AVEC LESQUELLES LES CYLINDRES2 VIENNENT ALTERNATIVEMENT EN COMMUNICATION, CES LUMIERES HAUTE ET BASSE PRESSION8 ETANT RELIEES AU CIRCUIT D'UTILISATION; AU MOINS UNE DES LUMIERES DE DISTRIBUTION8 PRESENTE UNE EXTREMITE AMONT DONT LA POSITION ANGULAIRE EST REGLABLE. LA PRESENTE INVENTION A POUR BUT D'AMELIORER LE RENDEMENT DES POMPES A BARILLET.
