Centrifugal vapour separating fuel pump - whose liquid and vapour outlet chambers have respective discharge impellers

摘要

A centrifugal vapour-separating fuel pump comprises a feed inlet chamber formed of two frustro-conical walls whose larger diameter ends are adjacent but separated by an annular impeller which discharges separated liquid. An axial vapour discharge tube has its lower end at the level of the liquid discharge impeller and has a vapour discharge impeller at its upper end. The tube itself is supported in a transverse partition.
