Abstract
CE DISTRIBUTEUR ELECTRO-HYDRAULIQUE D'ASSERVISSEMENT DU TYPE QUI COMPREND UN TIROIR DE DISTRIBUTION 24 QUI EST COMMANDE DANS UN MANCHON 26 PAR DES SIGNAUX DE PRESSION APPLIQUES A SES EXTREMITES ET QUI SONT EUX-MEMES ENGENDRES PAR LA POSITION D'UNE TUYERE 20 COMMANDEE PAR UN MOTEUR COUPLE 14 ET QUI SE DEPLACE DE L'UN A L'AUTRE DE DEUX ORIFICES PREVUS DANS UN BLOC 22. UN RESSORT DE REACTION 30 ETABLIT LA LIAISON ENTRE LE TIROIR 24 ET LA TUYERE 20. POUR FACILITER LE REMPLACEMENT DU RESSORT 30 (POUR LA COMPENSATION DES TOLERANCES DE FABRICATION ET LES VARIATIONS EVENTUELLES DES MATERIAUX), LA TUYERE 20 PORTE UN DOIGT ET LE RESSORT 30 SE TERMINE PAR UN ORGANE DE RETENUE 40 PRESENTANT DEUX JOUES PERCEES DE TROUS ALIGNES QUI RECOIVENT LES EXTREMITES DE LA BAGUE QUI PORTE LE DOIGT ET EST FIXE SUR LA TUYERE 20. UNE FENTE MENAGEE DANS LA JOUE SUPERIEURE DE LA TETE 40, DANS UNE POSITION INCLINEE PAR RAPPORT A L'ORIENTATION NORMALE DU DOIGT, PERMET D'ENFILER COMMODEMENT LA TUYERE 20 ET SON DOIGT DANS L'ORGANE 40. ON BLOQUE ENSUITE L'ORGANE 40 SUR LE DOIGT AU MOYEN DE VIS DE REGLAGE.
