Abstract

A body (6) for a check valve is mfd. in metal or rigid, heat resistant plastic. The valve is used in contact with hot and cold water. The valve body (6) has an internal compression spring (7), and a ball seal (8) and a sealing seat (9). and forms an integral part of a flexible tube system in partic. a T-junction (1). The body (6) is polyamide. USE/ADVANTAGE - In hot and cold water circuits using flexible pipes for controlling waterflow, partic. into a branch pipe. The valve operates without a power source.

Description

Die Erfindung betrifft eine Hülse als Grundkörper eines Rück­ schlagventiles bzw. eines Durchlaßbegrenzers gemäß Oberbegriff des Anspruchs 1. Hinsichtlich des Aufbaus derartiger Rückschlag­ ventile bzw. Durchlaßbegrenzer wird auf den allgemeinen Stand der Technik verwiesen.The invention relates to a sleeve as the base body of a back impact valves or a flow limiter according to the preamble of claim 1. With regard to the construction of such a setback valves or flow restrictor is on the general level referred to the technology.

Die Aufgabe der Erfindung besteht darin, unabhängig vom Motoraufbau den Kühlwasserfluß zu stoppen bzw. druck- oder drehzahlabhängig zu begrenzen. Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1.The object of the invention is independent of Engine body to stop the cooling water flow or pressure or limit depending on the speed. This task is solved by the characterizing part of claim 1.

Hinsichtlich zweckmäßiger Ausgestaltungen der Erfindung wird auf die Unteransprüche 2 und 3 verwiesen.With regard to expedient embodiments of the invention referred to subclaims 2 and 3.

Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Bezugnahme auf eine schematische Zeichnung erörtert. Dabei zeigt die einzige Abbildung eine Kfz-Formschlauchverzweigung (1) - hier als T-Krümmer ausgebildet - mit dem internen dreiarmigen Verzweigungsstück (2), an das die Krümmerschläuche (3, 4, 5) aus elastomerem Werkstoff angeschlossen sind (DE-C- 33 36 940). Die Hülse (6) als Teil des internen T-förmigen Verzweigungsstückes (2) und als Grundkörper des Rückschlag­ ventiles bzw. Durchlaßbegrenzers weist eine nach innen gerichtete Druckfeder (7), einen kugelförmigen Dichtkörper (8), einen Dichtsitz (9) und einen Zwangsdurchlauf (10) auf. The invention will now be discussed using an exemplary embodiment with reference to a schematic drawing. The only illustration shows a motor vehicle molded hose branch ( 1 ) - here designed as a T-bend - with the internal three-armed branch piece ( 2 ) to which the bend hoses ( 3 , 4 , 5 ) made of elastomeric material are connected (DE-C- 33 36 940). The sleeve ( 6 ) as part of the internal T-shaped branching piece ( 2 ) and as the base body of the check valve or passage limiter has an inwardly directed compression spring ( 7 ), a spherical sealing body ( 8 ), a sealing seat ( 9 ) and a positive pass ( 10 ).

Das Rückschlagventil bzw. der Durchlaßbegrenzer für den Kühlwasser- und Heizungskreislauf im Kfz sind somit ein integriertes Teil der Formschlauchverzweigung, womit die gestellte Aufgabe in überraschender Weise gelöst werden kann.The check valve or the flow restrictor for the The cooling water and heating circuit in the vehicle are therefore one Integrated part of the molded hose branch, with which the task can be solved in a surprising manner.

Für die Bildung einer Formschlauchverzweigung kann die Hülse (6) auch einen flanschartigen Rand aufweisen (DE-C-34 30 053).To form a molded hose branch, the sleeve ( 6 ) can also have a flange-like edge (DE-C-34 30 053).
