Embodiment Construction

[0021] The pressure hose according to the invention is Figures 1 to 3 are only partially shown with hose ends and are collectively marked with 1. The pressure hose 1 for a water distribution system is used in particular for connecting movable sanitary fittings such as kitchen sprinklers, shower nozzles or shower fittings or for connecting components of a water distribution system. Hose and jacket.

[0022] The inner hose is formed by a corrugated hose 2 made of plastic, which is preferably configured in a parallel corrugated manner. The inner corrugated hose 2 is surrounded by a braided sheath 3 which is attached directly to the inner corrugated hose 2 .

[0023] The corrugated hose 2 made of plastic can be made of polyethylene, for example. The jacket 3 is formed by a braid made of plastic, metal or a combination of these materials. As a metal, first consider high-quality alloy steel or aluminum.

[0024] As shown in the figure, at least one end of the pressure hose 1 i...

Abstract

The invention relates to a functional pressure hose for a water-carrying system, which has an inner hose made of plastic and an outer jacket made of a braided material extended in the whole pressure hose length. At least one pressure hose end is provided with a connector piece having a tubular connector, onto which the pressure hose end is pressed to the connector from exterior by means of a pressing sleeve. The hose demonstrates great flexibility while maintaining the required pressure strength, but at the same time guarantees great bending protection. The inner hose is formed by a corrugated hose which has parallel corrugations and is extended in the whole pressure hose length, the corrugated hose is directly surrounded by the outer jacket, 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 inner hose is surrounded by the pressing sleeve and is pressed into a groove of the connector formed by the ring beads by means of the pressing sleeve.

Description

technical field [0001] The invention relates to a pressure hose for a water supply system, in particular for connecting movable sanitary fittings or for connecting parts of a water supply system, having an inner hose made of plastic and an outer jacket made of braid, wherein , at least one hose end is provided with a connection piece with a tubular connection nipple onto which the hose end is pushed. Background technique [0002] Pressure hoses of this type have long been used in a variety of ways, especially in the hygiene sector. In this case, a smooth plastic inner hose is used as the water-carrying, fluid-tight medium and the sheath made of braid serves for pressure stabilization. Such hoses have hitherto been limited in their flexibility, since the inner hose is relatively rigid, at least if the wall thickness is correspondingly large in order to ensure sufficient longitudinal bending protection. [0003] For other fields of application, pressure hoses are also known ...
