    摘要: A self-priming pistonless lift pump has a first elongate tubular cylinder within which a second elongated tubular cylinder is loosely contained and freely slidable, the respective cylinders having inlet valves at their lower ends, and at their upper ends having fluid outlets, the outlet of the second tubular cylinder being transversely aligned with the outlet of the first cylinder when the second cylinder is in a lowermost position of travel within the first cylinder.
