Abstract

In the case of a pressure hose consisting of PVC material, especially for washing machines and dishwashers, a hose liner (2) is inserted into the hose line (1) at the connecting ends, which hose line (1) is connected to the hose liner (2) via a hose socket (5) which is pushed on from the outside. The hose liner (2) carries a sealing ring (6) consisting of an elastomer. <IMAGE>

Description

Druckschlauchpressure hose

Die Erfindung bezieht sich auf einen Druckschlauch, insbesondere für den Wasseranschluß von Wasch- oder Geschirrspülmaschinen, mit einer Schlauchleitung aus einem flexiblen Werkstoff, wobei an den Anschlußenden die Schlauchleitung über eine von außen aufgeschobene Schlauchfassung mit einer in die Schlauchleitung eingesteckten Schlauchtülle kraftschlüssig verbunden ist.The invention relates to a pressure hose, in particular for the water connection of washing machines or dishwashers, with a hose line made of a flexible material, with the hose line over at the connection ends a hose fitting pushed on from the outside with one plugged into the hose line Hose nozzle is positively connected.

Wasseranschlußschlauche der vorgenannten Art sind bislang in der Regel mit einer Schlauchleitung aus einem Kautschukmaterial hergestellt worden. Da man aber mit der Alterungsbeständigkeit der Kautschukleitungen nicht immer ganz zufrieden war, ist man nun auch dazu übergegangen, die Schlauchleitung aus PVC vorzusehen.Up to now, water connection hoses of the aforementioned type have generally been used been made with a hose line made of a rubber material. Since you but not always completely satisfied with the aging resistance of the rubber cables the PVC hose line has now also been used.

Bei diesen Schlauchleitungen aus PVC kann man davon ausgehen, daß sie nicht so sehr der Alterung ausgesetzt sind, jedoch zeigen sich hier im Anschlußbereich der Schlauchtüllen hin und wieder Undichtigkeiten.With these hose lines made of PVC one can assume that they are not so much exposed to aging, but show up here in the connection area the hose nozzles leak from time to time.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckschlauch der eingangs genannten Art zu schaffen, bei dem Undichtigkeiten im Anschlußbereich der Schlauchtüllen vermieden werden.The invention is based on the object of providing a pressure hose To create the type mentioned above, in the case of leaks in the connection area of the Hose nozzles are avoided.

Dei Lösung dieser Aufgabe wird durch die im Hauptanspruch gekennzeichneten Merkmaie erzielt. Weitere Merkmale und Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Dei solution to this problem is characterized by the main claim Merkmaie achieved. Further features and configurations of the invention result from the subclaims.

Bei der erfindungsgemäßen Lösung wird von der Erkenntnis ausgegangen, daß eine Schlauchleitung aus PVC über schlechtere Kaltfluß-Eigenschaften -verfügt, als wie dies z.B. bei einer Schlauchleitung aus Kautschuk der Fall ist.The solution according to the invention is based on the knowledge that that a hose made of PVC has poorer cold flow properties, than is the case, for example, with a rubber hose line.

Deswegen kann es nach dem Aufpressen der Schlauchfassung im übergangsbereich zwischen der Innenseite des PVC-Schlauches und der eingesteckten Schlauchtülle zu Undichtigkeiten kommen. Durch den erfindungsgemäßen Einsatz eines an sich bekannten O-Ringes wird dies jedoch in einfacher Weise vermieden.Therefore, after the hose socket has been pressed on, there may be a problem in the transition area between the inside of the PVC hose and the inserted hose nozzle Leaks come. By using a known per se according to the invention O-ring, however, this is avoided in a simple manner.

Ein Ausführungsbeispiel der Erfindung wird in der Zeichnung schematisch dargestellt. Die einziqe Zeichnung zeigt ein Anschlußende eines Druckschlauches z.B.für Wasch- oder Geschirrspülmaschinen im Schnitt.An embodiment of the invention is shown schematically in the drawing shown. The single drawing shows a connection end of a pressure hose e.g. for washing machines or dishwashers on average.

In der Zeichnung ist das Anschlußende des Druckschlauches für den Anschluß an das Wasserversorgungsnetz gezeigt. In die Schlauchleitung 1 aus PVC ist eine Schlauchtülle 2 aus einem Thermoplast,z.B. einem Polyamid, eingesteckt. über dem Flansch 3 der Schlauchtülle 2 befindet sich eine Uberwurfmutter 4 für die Anschlußverschraubung.In the drawing, the connection end of the pressure hose is for the Connection to the water supply network shown. In the hose line 1 made of PVC is a hose nozzle 2 made of a thermoplastic, e.g. a polyamide, inserted. Above the flange 3 of the hose nozzle 2 there is a union nut 4 for the Screw connection.

Über die Schlauchleitung 1 ist eine Schlauchfassung 5 in Form einer Metallhülse gestülpt. Die Schlauchtülle 2 weist nun eine Ringnut auf, in die ein O-Ring 6 eingelegt ist. Von außen wird die Metallhülse 5 mit der Schlauchleitung 1 und der Schlauchtülle 2 verpreßt, so daß hier eine unlösbare Verbindung hergestellt wird. Der eingelegte O-Ring verhindert nun mit Sicherheit ein Austreten von Leckwasser in diesem Anschlußbereich, wenn sich durch die zuvor erwähnte negative Kaltfluß-Eigenschaft des PVC-Materials im Übergangs bereich zur Schlauchtülle Undichtigkeiten ergeben.About the hose line 1 is a hose socket 5 in the form of a Slipped metal sleeve. The hose nozzle 2 now has an annular groove into which a O-ring 6 is inserted. From the outside, the metal sleeve 5 with the hose line 1 and the hose nozzle 2 pressed, so that a permanent connection is made here will. The inserted O-ring now reliably prevents leakage of water in this connection area if going through the aforementioned negative Cold flow property of the PVC material in the transition area to the hose nozzle leaks result.

Vorteilhafterweise wird der O-Ring 6 in einer hinter einer Rippe 7 der Schlauchtülle 2 angeordneten Ringnut eingelegt. Andererseits wäre es aber auch denkbar, den O-Ring nur auf die Schlauchtülle aufzuschieben, oder aber die Ringnut direkt in einer Rippe der Schlauchtülle anzuordnen.The O-ring 6 is advantageously located behind a rib 7 the hose nozzle 2 arranged annular groove inserted. On the other hand, it would also be conceivable to push the O-ring only onto the hose nozzle, or the ring groove to be arranged directly in a rib of the hose nozzle.

Zum gleichen Zweck könnte an der Schlauchtülle 2 der aus einem Elastomer bestehende elastische Dichtung auch direkt angespritzt sein.For the same purpose, the hose nozzle 2 could be made of an elastomer existing elastic seal can also be molded directly.
