Abstract

La présente invention concerne une pompe à engrenage capable de distribuer un fluide alternativement dans deux circuits d'utilisation distincts sans commutateur. La pompe à engrenage (1) est caractérisée en ce qu'elle comporte deux orifices de sortie de fluide (5, 6) raccordés à deux circuits d'utilisation du fluide et communiquant avec la chambre de refoulement (C) de la pompe par l'intermédiaire de moyens de commutation (7) intégrés. Ces moyens de commutation (7) comportent deux circuits de répartition (50, 60) prévus dans une platine (70) fixe et deux canaux tampon (30, 40) prévus dans les roues dentées (3) rotatives, agencés pour ouvrir et fermer lesdits circuits de répartition alternativement, selon un cycle de commutation correspondant sensiblement à la rotation des roues dentées sur un demi tour.
