<p><P>PROBLEM TO BE SOLVED: To provide a flexible ceramic hose which can reduce the necessary number of short ceramic pipes, a manufacturing cost, and its weight while securing its wear resistance and flexibility. <P>SOLUTION: A plurality of the short ceramic pipes 3 are stuck by vulcanizing on the inside surface of an outer rubber hose 2 in the state that the short ceramic pipes 3 are fitted with a required gap G so as to relatively bend. The gap G is provided between the conical concave surface 9 at one end portion 3a of each of neighboring short ceramic pipes 3, 3 in the axial direction of the hose on the upstream side of the flow of a fluid and the conical convex surface 10 at the other end portion 3b on the downstream side of the flow of the fluid. The gap G is formed such that the corner portion 12, where the conical convex surface 10 crosses the inner circumferential surface 11, overlaps with the corner portion 14, where the conical concave surface 9 crosses the outer circumferential surface 13, when the gap G is viewed from just above the axis P of the hose. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
