摘要： A collapsible, self-priming hose has a flexible inner tube extending along the interior of the outer tube, which has a diameter sufficiently greater than that of the inner tube to provide an intermediate space between the inner and outer tubes upon inflation of the outer tube. Retainer members extending between and connected to the inner and outer tubes expand the inner tube from a collapsed condition upon inflation of the outer tube and are flexible to allow the hose to collapse on deflation of the inner and outer tubes.
