Title:
タービン燃料ポンプのインペラ
Document Type and Number:
Japanese Patent JP4359450
Kind Code:
B2
Abstract:
A multiple-channel, single stage, turbine fuel pump impeller, preferably for use with vehicle fuel delivery systems. The impeller includes independent inner and outer vane arrays concentrically disposed to one another and radially spaced apart. The inner and outer vane arrays respectively communicate with independent inner and outer pumping chambers, each of which receives fuel at an inlet end from a common fuel inlet passage and expels fuel at an outlet end into a common fuel outlet passage. Furthermore, the pumping efficiency and overall performance of the pump is increased by utilizing an impeller where each vane: i) includes a linear root segment and a curved tip segment, ii) has a V-shape that opens in the direction of rotation, and iii) includes a rounded surface or radius on a trailing edge, to name but a few of the attributes of the vanes.
