Title:
LOW GAS-PERMEABLE COOLANT HOSE
Document Type and Number:
Japanese Patent JP2001030365
Kind Code:
A
Abstract:

To restrain penetration of gas and keep a hose pliable and further upgrade the performance to inhibit the gas permeability of the hose.

This coolant hose has a reinforcing yarn layer 3 formed by braiding fiber yarn 3a. In this case, a low gas-permeable outer resin layer 3b is formed to fill a gap between the fiber yarns 3a, on the entire periphery of the reinforcing yarn layer 3. Consequently, an outer resin layer 3b has irregularities, which enable a stretching effect to be displayed to keep the hose pliable. In addition, a low gas-permeable inner resin layer 1 is formed inside the outer resin layer 3b, and thus the two low gas-permeable resin layers 1, 3b are provided and the performance to inhibit the gas permeability of the hose is further enhanced.
