Abstract

CETTE POMPE A ENGRENAGES 14 SERT AU POMPAGE DE LIQUIDES CONTENANT DES GAZ. ELLE COMPORTE UN CONDUIT D'ECHAPPEMENT 26, POUR L'EVACUATION DES GAZ EMPRISONNES QUI RISQUENT DE SE RASSEMBLER SUR LE COTE "REFOULEMENT" DE LA POMPE. LE CONDUIT 26 A SON EXTREMITE SITUEE A L'INTERIEUR DU CORPS DE POMPE 21, DANS UNE ZONE SITUEE EN DEHORS DES ECOULEMENTS DE LIQUIDE DEPLACES PAR LES PIGNONS 24, 25, ET DANS L'ESPACE COMPRIS ENTRE CES DEUX PIGNONS. UN CONDUIT D'ENTREE AUXILIAIRE 27 PEUT DIRIGER DU LIQUIDE TRANSVERSALEMENT A L'ORIFICE D'ASPIRATION PRINCIPAL 22, VERS L'INTERVALLE EXISTANT ENTRE LA PERIPHERIE DE L'UN DES PIGNONS 25 ET LE CORPS DE POMPE 21. ON EVITE AINSI LES RISQUES DE DESAMORCAGE DE LA POMPE, NOTAMMENT DANS LES CIRCUITS D'HUILE POUR LA LUBRIFICATION DE MOTEURS D'AVIONS A TURBINE A GAZ.
