END SEAL STRUCTURE OF HOSE WITH BELLOWS TYPE METALLIC PIPE
Document Type and Number:
Japanese Patent JP3960159
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To solve a problem that a part positioned on a space of a bellows metallic pipe is expanded or ruptured by an inner pressure by a space between an inward flange part of a socket metallic fitting and a tip of a hose body when fixing the hose body having the bellows metallic pipe on an innermost layer to a connecting tool on a mating side by caulking of the socket metal fitting.
SOLUTION: The socket metal fitting 16 is fitted onto the hose body 12 having the bellows metallic pipe 18 on the innermost part by caulking, and is fixed to the connecting tool 14. An axial end side of the bellows metallic pipe 18 is exposed and extended from an outer layer, and the extended part 36 is fitted to the connecting tool 14 by caulking of the socket metal fitting 16. An outside rubber layer 24 intervenes on an inner surface side of the socket metal fitting 16 as a filling material layer, the outside rubber layer 24 runs into a space S by caulking of the socket metal fitting 16, and the space is filled. The inner pressure actuating to the extended part 36 is supported from the radial direction outside.
