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.

Abstract: Hose (70) has a biasing spring (76) extends along the full length. Spring (76) is covered with hose cover material (72) on the outside and hose support layer (74) and hose sealing layer (72) on the inside to form a sealed hose.

Abstract: A self-actuated linearly retractable and extendible hose (70) for use in transporting fluids (liquids, gases, solid particles, and combinations of these three) between a source location and a output location. Hose (70) has a biasing spring (76) extends along the full length. Spring (76) is covered with hose cover material (72) on the outside and hose support layer (74) and hose sealing layer (72) on the inside to form a sealed hose.

Control of fluid pressure within hose (70) allows the hose to operate as an automatically extendable and retractable hose. When hose (70) is pressurized by a fluid source, the internal pressure of the hose overcomes the retracting force of spring (76) and the hose extends.

Abstract: A flexible garden hose having an inner tube member made from elastic material and an outer tube member made from a non-elastic material.
