  • Patent number: 6698457
    Abstract: A flexible hose which has a hose body made of soft synthetic resin, a reinforcement made of hard synthetic resin wound spirally and joined to the hose body by fusion, and a conductor arranged inside the reinforcement in its longitudinal direction. The conductor does not adhere to the reinforcement and is movable. The hose body is formed by: extruding a tube made of soft resin from a head of an extruder; pressing and flattening the tube to form a strip; and winding the strip spirally with the adjacent side edges joined together.
    Type: Grant

  • Patent number: 6024132
    Abstract: The flexible hose comprises a bellows hose wall 1 composed of an inner wall 2 and an outer wall 3 each made of a soft resin and a spiral hard reinforcement 4 interposed therebetween. As the hose contracts, a spiral groove 7 is formed inside of the hose. The inner wall 2 is not partially bonded or fused with the outer wall 3 and the hard spiral reinforcement 4 to form unbonded sites or fragments 8. As the hose contracts, the unbonded fragments 8 are separated from the outer wall 3 and the spiral hard enforcement 4 and move to the inward direction of the hose, and close the spiral groove 7. Therefore, even a fluid flows to any longitudinal direction, the flexible hose reduces a flow resistance.
