Abstract

CETTE POMPE, NOTAMMENT POUR DIRECTION ASSISTEE DE VEHICULES COMPREND UNE CAME FIXE NON CIRCULAIRE 28 DEFINISSANT DES ARCS DE POMPAGE ET UN ROTOR 38 PORTANT DES PALETTES. AFIN DE REDUIRE LE BRUIT ET LES INCONVENIENTS DES PULSATIONS DE PRESSION, DES CANAUX MENAGES DANS LES PLAQUES 46, 48 QUI ENCADRENT LE ROTOR ET LA CAME, EQUILIBRENT LES PRESSIONS ENTRE LE VOLUME DE FLUIDE COMPRIS ENTRE DEUX PALETTES SITUEES AU BORD AVAL D'UN ORIFICE DE SORTIE A HAUTE PRESSION ET LE VOLUME COMPRIS ENTRE DEUX PALETTES SITUEES AU DROIT DU BORD AVAL D'UN ORIFICE D'ENTREE A BASSE PRESSION. UN DISTRIBUTEUR 24 ETABLIT UNE DERIVATION RENVOYANT LE REFOULEMENT A L'ENTREE DE LA POMPE LORSQUE LA DIRECTION ASSISTEE N'A PAS BESOIN DE FLUIDE. CE DISTRIBUTEUR TRAVAILLE A LA FOIS EN REPONSE A LA PRESSION STATIQUE DU REFOULEMENT ET A LA PRESSION DYNAMIQUE RESULTANT DE LA VITESSE DU COURANT DE REFOULEMENT DE MANIERE A OUVRIR PLUS FORTEMENT LA DERIVATION AUX GRANDES VITESSES DE FONCTIONNEMENT DE LA POMPE, DE MANIERE QUE LE TAUX D'ACCROISSEMENT DU DEBIT DE LA POMPE SOIT PLUS FAIBLE AUX GRANDES VITESSES QU'AUX PETITES VITESSES.
