<p><P>PROBLEM TO BE SOLVED: To provide a flexible hose without causing the leakage of a high pressure coolant to the atmosphere. <P>SOLUTION: The flexible hose 18 is constituted by arranging an inner tube 19 in an outer tube 20 and by the terminal processing of both ends by connecting metal fittings 21 of coaxial double structure. Such flexible hose 18 is connected to a joint part of a compressor of coaxial double structure and a joint part of a condenser of coaxial double structure, the high pressure coolant flows in the inner tube 19, and a low pressure coolant flows in a passage between the inner tube 19 and the outer tube 20. Thus, even if the high pressure coolant infiltrates the inner tube 19, the destination of infiltration is the passage for the low pressure coolant, and therefore the high pressure coolant does not leak to the atmosphere directly. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
