Abstract

The container comprises a coolant reservoir (11) with connection to a radiator, an overflow reservoir chamber (15) as well as a further third chamber (16) having at the geodetic lower end an opening connecting to the overflow reservoir which in turn is connected to the first coolant reservoir through an excess pressure valve (20). The excess pressure valve is set in the closure cap of the radiator.

Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Behälter für das Kühlmittel einer Brennkraftmaschine nach den Merkmalen des Oberbegriffs des unabhängigen Anspruchs 1.The invention relates to a container for the coolant of an internal combustion engine according to the features of the preamble of independent claim 1.

Ein solcher Behälter ist beispielsweise aus der WO-A-99 106 36 bekannt.Such a container is known for example from WO-A-99 106 36.

Der Erfindung liegt die Aufgabe zugrunde, einen Behälter für das Kühlmittel einer Brennkraftmaschine zu schaffen, welcher wirtschaftlich herstellbar ist sowie zuverlässig unter verschiedenen Betriebsbedingungen arbeitet. Diese Aufgabe wird ausgehend von dem Oberbegriff des unabhängigen Anspruchs 1 durch dessen kennzeichnenden Merkmale gelöst.The invention has for its object to provide a container for the coolant of an internal combustion engine, which is economical to produce and operates reliably under different operating conditions. This object is achieved on the basis of the preamble of independent claim 1 by its characterizing features.

Vorteile der ErfindungAdvantages of the invention

Der wesentliche Vorteil der Erfindung ist darin zu sehen, dass in dem Behälter ohne größeren Aufwand eine dritte Kammer angeordnet wird, welche die Schlauchverbindung ersetzt und zuverlässig arbeitet. Der Behälter für das Kühlmittel weist ein Überdruckventil auf. Die dritte Kammer steht mittels des Überdruckventils mit der ersten Kammer in Verbindung. Das Überdruckventil begrenzt das Abfließen der Flüssigkeit aus der ersten Kammer unterhalb eines bestimmten eingestellten Druckwertes. Dieses Überdruckventil ist gemäß einer Ausgestaltung der Erfindung in der Verschlußkappe des Kühlmittelreservoirs bzw. des Behälters angeordnet.The main advantage of the invention is the fact that in the container, a third chamber is arranged without much effort, which replaces the hose connection and works reliably. The container for the coolant has a pressure relief valve. The third chamber communicates with the first chamber by means of the pressure relief valve. The pressure relief valve limits the outflow of liquid from the first chamber below a certain set pressure value. This pressure relief valve is arranged according to an embodiment of the invention in the closure cap of the coolant reservoir or of the container.

Die dritte Kammer ist mit einem rohrförmigen Querschnitt versehen und befindet sich an der Wand zwischen der ersten und der zweiten Kammer. Der Aufbau bzw. das Herstellverfahren für diese dritte Kammer ist einfach und wirtschaftlich, es genügt die Trennwand zwischen erster und zweiter Kammer mit einem zusätzlichen Rohrprofil zu versehen. Der Behälter besteht aus thermoplastischem Kunststoff und wird aus zwei Teilen, nämlich einer unteren und einer oberen Behälterhälfte hergestellt werden. Beide Behälterhälften sind miteinander verschweißt oder verklebt. Da die zweite Kammer einen Auslauf für das Abfließen von überschüssigem Kühlmittel aufweist, ist diese Kammer druckfrei ausgeführt. Ebenso die dritte Kammer.The third chamber is provided with a tubular cross-section and is located on the wall between the first and the second chamber. The structure and the manufacturing method for this third chamber is simple and economical, it is sufficient to provide the partition between the first and second chamber with an additional tube profile. The container is made of thermoplastic material and will be made of two parts, namely a lower and an upper half of the container. Both container halves are welded or glued together. Since the second chamber has an outlet for the outflow of excess coolant, this chamber is designed pressure-free. Likewise the third chamber.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Der Behälter 10 besteht im wesentlichen aus einer unteren Behälterhälfte 12 und einer oberen Behälterhälfte 13. Beide Behälterhälften sind im mittleren Bereich mit Flanschverbindungen 14 versehen, durch Ultraschallschweißen werden diese beiden Behälterhälften miteinander im Bereich der Flanschverbindung flüssigkeitsdicht verbunden. Der Behälter 10 bildet damit eine erste Kammer 11, eine zweite Kammer 15 und eine dritte Kammer 16. Zum Einfüllen von Flüssigkeit in den Behälter 10 ist im oberen Bereich ein Schraubstutzen 17 vorgesehen mit einer Öffnung 18. Auf dieser Öffnung 18 befindet sich eine Verschlußkappe 19. Die Verschlußkappe ist mit einem Überdruckventil 20 ausgestattet. Dieses Überdruckventil 20 besteht aus einem Ventilteller 21, der längs beweglich in der Verschlußkappe 19 gelagert ist. Es ist weiterhin eine Druckfeder 22 vorgesehen die eine Kraft auf den Ventilteller in axialer Richtung ausübt. Der Ventilteller verschließt eine Ventilöffnung 23 in der Verschlußkappe 19. Bei einem in der Kammer 11 herrschenden Überdruck der über einem bestimmten vorgegebenen Wert hinaus ansteigt, öffnet das Überdruckventil 20 und gibt einen Verbindungskanal 24 zwischen der ersten Kammer 11 und der dritten Kammer 16 frei. Die dritte Kammer 16 ist am unteren Bereich mit der zweiten Kammer 15 über eine Öffnung 25 verbunden. Die zweite Kammer 15 ist an ihrem geodätisch oberen Ende mit einem Auslauf 26 ausgestattet.The container 10 consists essentially of a lower container half 12 and an upper container half 13. Both container halves are in the central region with flange connections 14 provided by ultrasonic welding, these two container halves are liquid-tightly connected to each other in the flange connection. The container 10 thus forms a first chamber 11, a second chamber 15 and a third chamber 16. For filling of liquid in the container 10, a screw 17 is provided with an opening 18 in the upper area. On this opening 18 is a closure cap 19th The cap is equipped with a pressure relief valve 20. This pressure relief valve 20 consists of a valve plate 21 which is mounted longitudinally movable in the cap 19. It is further provided a compression spring 22 which exerts a force on the valve disk in the axial direction. The valve disc closes a valve opening 23 in the cap 19. When a prevailing in the chamber 11 pressure above a certain predetermined value addition, opens the pressure relief valve 20 and releases a connecting channel 24 between the first chamber 11 and the third chamber 16. The third chamber 16 is connected at the lower area with the second chamber 15 via an opening 25. The second chamber 15 is equipped at its geodesic upper end with an outlet 26.

Figur 2 zeigt die Anordnung der dritten Kammer 16 innerhalb der zweiten Kammer 15. Die dritte Kammer ist lediglich in Form eines Rohrprofils an der Trennwand 27 angeordnet. Aus der Darstellung wird deutlich, dass diese dritte Kammer dazu dient, eine Verbindung zwischen erster und zweiter Kammer zu schaffen, die geeignet ist, bei einem Abfallen des Drucks in der ersten Kammer Flüssigkeit von der zweiten Kammer in die erste Kammer zurückzutransportieren. Hierzu ist das Überdruckventil 20 mit einer Rücklaufklappe versehen, die es ermöglicht, dass die Flüssigkeit über den Verbindungskanal in die erste Kammer zurückströmen kann. Der Behälter ist in bevorzugterweise aus transparentem Kunststoff ausgeführt, so dass der Flüssigkeitsstand kontrolliert werden kann ohne dass die Verschlußkappe abgenommen werden muss. Die erste Kammer ist über eine hier nicht dargestellte Öffnung mit dem Kühler der Brennkraftmaschine verbunden und sorgt dafür, dass im Kühler ausreichend Kühlflüssigkeit vorhanden ist.Figure 2 shows the arrangement of the third chamber 16 within the second chamber 15. The third chamber is arranged only in the form of a tubular profile on the partition wall 27. It will be understood from the illustration that this third chamber serves to provide communication between the first and second chambers suitable for transporting liquid from the second chamber back into the first chamber as the pressure in the first chamber falls. For this purpose, the pressure relief valve 20 is provided with a return flap, which makes it possible that the liquid can flow back into the first chamber via the connecting channel. The container is preferably made of transparent plastic, so that the liquid level can be controlled without the cap must be removed. The first chamber is connected via an opening, not shown here, with the radiator of the internal combustion engine and ensures that sufficient cooling fluid is present in the radiator.
