Abstract
In certain embodiments, a hose includes an inner tube, a filler material, and an outer cover. The inner tube has a cross-sectional shape and includes a cavity for transporting a substance. The filler material is provided around an outer periphery of the inner tube. The filler material includes a self-sealing material or a self-healing material. The outer cover is provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube. The outer cover has a D-shaped cross-sectional shape.
Claims20
A method for forming a hose, the method comprising:
- providing an inner tube comprising a cavity for transporting a substance;
- forming a filler material into a first cross-sectional shape around an outer periphery of the inner tube, the first cross-sectional shape having at least one elongated edge;
- and
- enclosing the filler material in an outer cover such that the filler material is positioned between the outer cover and the inner tube, the outer cover being formed into a shape that matches the first cross-sectional shape of the filler material such that the outer cover has the first cross-sectional shape, a thickness of the filler material between the inner tube and the at least one elongated edge of the outer cover being less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover.
A method for forming a hose, comprising:
- providing an inner tube having a cross-sectional shape, the inner tube comprising a cavity for transporting a substance;
- forming a filler material into a D-shaped cross-sectional shape around an outer periphery of the inner tube, the filler material comprising a self-sealing material or a self-healing material;
- and
- enclosing the filler material in an outer cover such that the filler material is between the outer cover and the inner tube, the outer cover being formed into the D-shaped cross-sectional shape, the D-shaped cross-sectional shape comprising a first elongated edge, the inner tube being positioned such that a thickness of the filler material between the inner tube and the first elongated edge of the outer cover is less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover.
A method, comprising:
- receiving a hose that comprises:
- an inner tube comprising a cavity for transporting a substance;
- a filler material provided around an outer periphery of the inner tube, the filler material comprising a self-sealing material or a self-healing material;
- an outer cover provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube, the outer cover having a cross-sectional shape that comprises one or more flat edges, a thickness of the filler material between the inner tube and at least one flat edge of the one or more flat edges of the outer cover being less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover;
- and
- positioning the at least one flat edge of the hose toward a surface of a machine such that a greater amount of filler material is configured to be oriented toward a potential threat.
