Abstract

The invention discloses a hose (10) which comprises at least one tubular layer (3) of plastic or rubber material, a mesh-network (4) of the chain type presenting mesh lines (5) and mesh rows (6) having a tubular shape being wound on the external surface of said inner layer, a possible external layer (7), and is characterized in that said mesh rows are slanted in relation to the longitudinal axis of the hose. According to a preferred embodiment the lines (5) of said meshes are slanted in relation to the longitudinal axis Y of the hose, following a direction opposite to the direction of the mesh rows (6).

Claims

1. A hose, from the interior to the exterior, comprising:

at least one tubular inner layer of plastic or rubber material having an exterior surface;

a chain-type mesh-network having mesh lines and mesh rows, said chain-type mesh-network having in a single layer a tubular shape and being wound one the exterior surface of said inner layer, wherein said mesh rows and mesh lines being slanted in directions, substantially perpendicular to each other such that the angle of inclination of the mesh rows relative to the longitudinal axis of the hose is substantially equal to the angle of inclination of the mesh lines relative to the longitudinal axis of the hose for eliminating torsion effects resulting from pressure changes within the hose; and

an external layer disposed over the chain-type mesh-network for the protection thereof.

2. A hose according to claim 1 wherein said chain-type mesh-network has parallel lines of said mesh lines and mesh rows slanted in relation to the longitudinal axis of the hose.

3. A hose according to claim 1 wherein the mesh lines and mesh rows are formed of threads of substantially the same material.
