Fluid permeable hose carcass

A method of manufacturing a hose assembly comprising the steps of:

• passing a single metal strip through a die to form a plurality of channels extending from a first end to a second end of the strip;
• winding said strip on a mandrel to create a plurality of convolutions, each convolution of the plurality of convolutions having first and second ends, wherein the plurality of channels extend from the first end to the second end;
• fastening adjacent convolutions together at an interlocked joint to form a continuous carcass having an inner and outer diameter about a central axis, wherein a first end of a convolution of the plurality of convolutions interlocks with a second end of an adjacent convolution;
• 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.

A method of manufacturing a hose assembly comprising the steps of:

• embossing a metal strip with a plurality of channels comprising adjacent ridges and valleys, the plurality of channels extending continuously from a first end to a second end of the strip;
• passing a single metal strip through a die to form a substantially S-shaped ribbon having inner and outer body portions and inner and outer lips that extend from the inner and outer body portions, respectively, the lips defining the first and the second end;
• winding said strip on a mandrel to create a plurality of convolutions, each convolution of the plurality of convolutions having the first and second ends, wherein the plurality of channels extend from the first end to the second end, wherein during the winding the inner lip is interfitted with the outer lip, wherein the interfitted inner and outer lips create at least one fluid passage between the inner and outer diameters in each of said interfitted inner and outer lips utilizing the channels, the interfitting forms a continuous carcass having an inner and outer diameter about a central axis, wherein the first end of a convolution of the plurality of convolutions interlocks with a second end of an adjacent convolution;
• 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.
