Abstract
Abstract This invention relates to hoses reinforced by metal cables. According to the invention, the reinforcement comprises two or more cables separated by a rubber layer, these cables being helically wound to form, with the axial direction of the hose, an angle equal to or greater than 70*, and preferably equal to or greater than 80*. The layers are crossed and the cables of one layer form, with the hose axial direction, an angle equal to and of sense opposite to that of said axial direction and the cables of said other layer. Supplementary reinforcement may be provided, if required, and comprising an extra thicker metal wire that is helically wound so that its convolutions form an angle not less than 80* with the hose axis or, alternatively, laminated rings located at right angles to the hose axis and constituted by concentric windings of metal strips: such supplementary reinforcement is located in the rubber layer located between the said cable layers.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A hose for resisting substantially deforming external pressures consisting of a unitary rubbery sheath internally reinforced by metal reinforcement, said reinforcement comprising at least two pairs of helically wound metal cables, one pair disposed within the other pair with the one pair being separated from the other pair by an intervening zone of rubber, said pairs of cables being located in proximity to the respective wall faces of said rubbery sheath, one of each pair of cables being wound in a helix the convolutions of which form with the longitudinal axis of said hose an angle of at least 70* and the second of each pair of cables also being wound in a helix the convolutions of which form with said longitudinal axis an angle of at least 70* but wound in such manner as to form a crossed helix with respect to said first cable of each pair and in spaced proximity to said first cable of each pair.
Claim 2
Dependent Claim
160 words
A hose for resisting substantially deforming external pressures consisting of a unitary rubbery sheath internally reinforced by metal reinforcement, said reinforcement comprising at least two pairs of helically wound metal cables, one pair disposed within the other pair with the one pair being separated from the other pair by an intervening zone of rubber, said pairs of cables being located in proximity to the respective wall faces of said rubbery sheath, one of each pair of cables being wound in a helix the convolutions of which form with the longitudinal axis of said hose an angle of at least 70* and the second of each pair of cables also being wound in a helix the convolutions of which form with said longitudinal axis an angle of at least 70* but wound in such manner as to form a crossed helix with respect to said first cable of each pair and in spaced proximity to said first cable of each pair.
Claim 3
Dependent Claim
41 words
A hose as claimed in claim 1 in which an additional helically wound metal wire the convolutions of which form with the longitudinal axis of said hose an angle of at least 80* is located within said intervening zone of rubber.
Claim 4
Dependent Claim
27 words
A hose as claimed in claim 2 in which said additional wire has an external diameter approximately equal to the thickness of said intervening zone of rubber.
Claim 5
Dependent Claim
40 words
A hose as claimed in claim 1 in which a plurality of laminated metal rings having their diameters at an angle of 90* with respect to the longitudinal axis of said hose are located within said intervening zone of rubber.
Claim 6
Dependent Claim
28 words
A hose as claimed in claim 4 in which said laminated metal rings have an external diameter approximately equal to the thickness of said intervening zone of rubber.
Claim 7
Dependent Claim
61 words
A hose as claimed in claim 1 which includes an alternating succession of cylindrical zones and bellows-forming zones, the reinforcement in said cylindrical zones only including an additional helically wound metal wire the convolutions of which forM with the longitudinal axis of said hose an angle of at least 80*, said additional wire being located within said intervening zone of rubber.
Claim 8
Dependent Claim
27 words
A hose as claimed in claim 6 in which said additional wire has an external diameter approximately equal to the thickness of said intervening layer of rubber.
Claim 9
Dependent Claim
61 words
A hose as claimed in claim 1 which includes an alternating succession of cylindrical zones and bellows-forming zones, the reinforcement in said cylindrical zones only including a plurality of laminated metal rings having their diameters at an angle of 90* with respect to the longitudinal axis of said hose, said laminated metal rings being located within said intervening layer of rubber.
Claim 10
Dependent Claim
28 words
A hose as claimed in claim 8 in which said laminated metal rings have an external diameter approximately equal to the thickness of said intervening layer of rubber.
Claim 11
Dependent Claim
23 words
A hose as claimed in claim 6 in which said bellows-forming portions are of greater diameter than said cylindrical zones of said hose.
Claim 12
Dependent Claim
23 words
A hose as claimed in claim 8 in which said bellows-forming portions are of greater diameter than said cylindrical zones of said hose.
