Abstract
A hose (10) comprising a tubular body (12) of flexible material arranged between an inner and an outer helically wound wire (22, 24). The hose (10) further comprises an axial strengthening means (20) adapted to reduce deformation of the tubular body (12) when the tubular body (12) is subjected to axial tension, the axial strengthening means (20) being adapted to exert a radially inward force on at least part of the tubular body (12) when axial strengthening means (20) is subjected to axial tension.
Claims43
A hose comprising a tubular body of flexible material arranged between an inner helical gripping member and an outer helical gripping member, the tubular body serving to transport fluid through the hose and to prevent fluid leakage through the body, the tubular body comprising an inner reinforcing layer wrapped around the inner helical gripping member, a sealing layer wrapped around the inner reinforcing layer, and an outer reinforcing layer wrapped around the sealing layer, whereby the two reinforcing layers sandwich the sealing layer therebetween, wherein the hose further comprises an axial strengthening means in the form of a generally tubular braid which is adapted to reduce deformation of the tubular body when the tubular body is subjected to axial tension, and wherein the axial strengthening means comprises a generally tubular sheath formed of a sheet material provided in a tubular shape, such that the tubular sheath can maintain the integrity of its tubular shape when subjected to axial tension.
