Abstract

A functional pressure hose for a water-carrying system, particularly for connecting movable sanitary fittings or for connecting parts of the water-carrying system with one another, has an inner hose made of plastic and an outer jacket made of a braided material. At least one hose end is provided with a connector piece having a tubular connector, onto which the hose end is pressed. The inner hose is formed by a corrugated hose, and the tubular connector has circumferential ring beads that are adapted to the inner contour of the corrugated hose. At least some of the ring beads are provided with notches that run axially. The hose demonstrates great flexibility while maintaining the required pressure strength, but at the same time guarantees great bending protection.

Claims (11)

1. A pressure hose for a water-carrying system, comprising:

an inner hose made of plastic and being formed as a corrugated hose with parallel corrugations;

an outer jacket made of a braided material and directly surrounding the inner hose;

at least one connector piece having a tubular connector, onto which a hose end is pressed by means of a pressure sleeve, said tubular connector having circumferential ring beads that are adapted to an inner contour of the corrugated hose,

wherein at least some of the ring beads are provided with notches that run axially.

2. The pressure hose according to claim 1 , wherein a distance between adjacent corrugations of the corrugated hose deviates from an axial width of the corrugations.

3. The pressure hose according to claim 2 , wherein the distance between adjacent corrugations of the corrugated hose differs along a length of the hose.

4. The pressure hose according to claim 1 , wherein an axial width of the corrugations of the corrugated hose differs along a length of the hose.

5. The pressure hose according to claim 1 , wherein the inner hose consists of polyethylene or polypropylene.

6. The pressure hose according to claim 1 , wherein the outer jacket consists of plastic or metal.

7. The pressure hose according to claim 1 , wherein the hose is configured as a pressure-resistant connecting hose, as a kitchen spray hose, or as a retractable hose for shower hoses.
