Abstract: A self-actuated linearly retractable and extendible hose for use in transporting fluids (liquids, gases, solid particles, and combinations of these) between a source location and an output location can be implemented as an extendible hose comprising a biasing element, a sealing layer, and a reinforced cover layer. The sealing layer forms a sealed conduit for transporting the fluids, and the reinforced cover layer on the outside provides radial and longitudinal strength for the sealing layer. The hose can be operated by increasing internal pressure within the hose relative to ambient pressure. When the hose is pressurized by a fluid source, the internal pressure of the hose overcomes the retracting force of the biasing element and the hose extends. When the fluid source is turned off or disconnected from the hose, internal pressure is reduced and the biasing element exerts a tension force on the hose causing the hose to retract.
