Abstract
A flexible hose assembly includes a flexible fluid permeable annular carcass arrangement having an inner and an outer diameter formed about a central axis. The carcass arrangement provides skeletal strength to the hose assembly against radial forces. The carcass arrangement has a plurality of interconnecting strips forming convoluted joints between the strips. The convoluted joints have an inner lip and an outer lip at opposite ends of the strips; and the carcass further comprises a plurality of channels formed along an entire length of first and second sides of the strips, the channels creating at least one fluid passage in each of the convoluted joint forming the carcass for the passage of fluids between the inner and outer diameters.

A flexible hose assembly comprising:
- a flexible fluid permeable annular carcass arrangement having an inner and an outer diameter formed about a central axis, the carcass arrangement providing skeletal strength to said hose assembly against radial forces, the carcass arrangement comprising a plurality of convolutions formed by a metal strip and fastened at convoluted joints between said convolutions, said convoluted joints having an inner lip and an outer lip at opposite ends of said convolutions;
- and
- the carcass further comprising a plurality of channels formed along an entire length of first and second sides of said strip, said channels creating at least one fluid passage in each of said convoluted joints forming said carcass for the passage of fluids between said inner and outer diameters.
A flexible hose assembly comprising:
- a flexible fluid permeable annular carcass arrangement having an inner and an outer diameter formed about a central axis, the carcass arrangement providing skeletal strength to said hose assembly against radial forces, the carcass arrangement comprising a plurality of convolutions formed by a metal strip and fastened at convoluted joints between said convolutions, said convoluted joints having an inner lip and an outer lip at opposite ends of said convolutions;
- and
- the carcass further comprising a plurality of notches spaced along said opposite ends of said strip, said notches creating at least one fluid passage in each of said convoluted joints forming said carcass for the passage of fluids between said inner and outer diameters.
A method of manufacturing a hose assembly comprising the steps of:
- passing a single metal strip through a die;
- winding said ship on a mandrel to create a plurality of convolutions;
- fastening adjacent convolutions together at an interlocked joint to form a continuous carcass;
- surrounding said continuous carcass with a sealing sheath;
- surrounding said sealing sheath with at least one braided layer;
- and
- surrounding said at least one braided layer with an external sheath.
