    摘要: A liquid fuel pump arrangement for delivering fuel to an engine comprises a liquid-ring pump (2) including a motor driven bladed impeller rotor (6) which is located eccentrically within a cylindrical bore of a chamber forming part of a hollow pump body structure. The hollow pump body (7) structure also accommodates a motor-driven prime pump impeller (5) which pumps fuel within the pump body structure to an aircraft or other engine. An inner end wall of the liquid ring pump provides the liquid ring with access to the liquid fuel within the pump body structure whilst an outer end wall of the liquid ring pump has an air/vapour inlet port (8) through which the bladed impeller of the liquid ring pump draws air/vapour, and an air/vapour outlet port (11), the flow of air/vapour expelled therefrom by compression of the air/vapour within the liquid ring being restricted by flow restriction means (12).
