Abstract

L'invention concerne un ensemble pompe à huile. Une première pompe est formée d'un premier corps de pompe (8), d'un rotor externe (1), d'un rotor interne (2), de rouleaux (4) et d'un deuxième corps de pompe (7). Une deuxième pompe est constituée du second corps de pompe (7), du rotor externe (1), du rotor interne (2), des rouleaux (4) et d'un troisième corps de pompe (6). La troisième pompe est formée du troisième corps de pompe (6), du rotor externe (1), du rotor interne (2), des rouleaux (4) et d'un quatrième corps de pompe (5). Toutes les pompes partagent le même arbre (3) relié à une roue dentée qui est raccordée par une chaîne au vilebrequin.
