Title
(EN) PUMP ASSEMBLY HAVING TWO PUMPS PROVIDED IN A SINGLE HOUSING
(FR) ENSEMBLE DE POMPES À DEUX POMPES DISPOSÉES DANS UN SEUL BOÎTIER
Abstract
(EN)
A pump assembly that has a first pump and a second pump for pumping lubricant, both pumps being integrated into a single housing. A drive shaft is provided that drives both pumps. Both the first pump and the second pump have a gear or rotor that is rotated by the drive shaft. Each of the pumps have an inlet provided on the housing to receive input from a source outside the housing and an outlet. The housing has a wall that is common to both pumps. The first pump is provided on a first side of the wall and the second pump is provided on the second, opposite side. The gears or rotors of the pumps may be provided in pockets provided on the first and second sides of the wall. The drive shaft extends through the wall and connects to each of the drive gears or rotors.

La présente invention concerne un ensemble de pompes qui comprend une première pompe et une seconde pompe permettant de pomper le lubrifiant, les deux pompes étant intégrées dans un seul boîtier. Un arbre d'entraînement sert à entraîner les deux pompes. La première pompe et la seconde pompe comprennent un engrenage ou un rotor que fait tourner l'arbre d'entraînement. Chacune des pompes comporte une entrée ménagée dans le boîtier pour recevoir une alimentation en provenance d'une source située à l'extérieur du boîtier et une sortie. Le boîtier a une paroi qui est commune aux deux pompes. La première pompe est disposée sur un premier côté de la paroi et la seconde pompe est disposée sur le second côté en regard. Les engrenages ou rotors des pompes peuvent être disposés dans des poches disposées sur les premier et second côtés de la paroi. L'arbre d'entraînement s'étend à travers la paroi et est relié à chacun des engrenages d'entraînement ou des rotors.
