Abstract: A hose arrangement includes an outer tube of flexible material and an inner tube of an elastic material for carrying fluid. Due to an action of the elastic inner tube, the hose has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when the fluid pressure is applied to the interior of the elastic inner tube. The tube has an undulating state in the contracted state and controls and contains expansion of the inner tube when the hose is in the expanded state. At least one sleeve portion is provided between the elastic inner tube and the outer tube along a part of the elastic inner tube where undulation of the outer tube occurs in the contracted state for protecting the elastic inner tube from abrasion undulations of the outer tube.
