【発明の名称】一体化燃料ポンプ組立体
Document Type and Number:
Japanese Patent JP3372373
Kind Code:
B2
Abstract:
A unified fuel pump assembly combines a vane-type pump and a booster stage for the inlet of the vane-type pump, in a unitary structure to substantially reduce "windage" losses caused by relatively moving parts. The unified structure also includes an electric motor subassembly to provide motive power, and a liquid ring pump, which helps to process air bubbles through the fuel pump, is coupled to the electric motor rotor to further avoid "windage" losses. The vane type pump relies on the use of a central shaft capable of having a substantially uniform and relatively large diameter from end to end.
