Nach der Herstellung des Ansaugverteilers im Blasformungsverfahren wird ein Flansch um die Rohre des Ansaugverteilers im Spritzgießverfahren geformt, um die Einleitung von Kurbelgehäusegasen zu verbessern.European Patent Application 0 567 702 A1 discloses a method of molding an intake manifold for an automotive engine. After the manufacture of the intake manifold in the blow molding process, a flange is injection molded around the pipes of the intake manifold to enhance the introduction of crankcase gases.

Die britische Patentanmeldung GB 2 203 487 A beschreibt ein Bauteil zur Einleitung von Kurbelgehäusegasen, welches zwischen Zylinderkopf und Ansaugverteiler einer Verbrennungskraftmaschine angeordnet ist. Das Bauteil ist mit Kraftstoffeinspritzern in Verbindung mit Kraftstoffzufuhr- und Kraftstoffrücklaufleitungen sowie mit den Zylindern des Motors kommunizierenden Luftzufuhrleitungen geformt.The British patent application GB 2 203 487 A describes a component for the introduction of crankcase gases, which is arranged between the cylinder head and intake manifold of an internal combustion engine. The component is molded with fuel injectors in communication with fuel supply and fuel return lines and air supply lines communicating with the cylinders of the engine.

Die internationale Patentanmeldung WO97/34081 offenbart ein relativ kompliziertes Verfahren, wobei ein Flansch zur Verteilung von Dämpfen oder Gasen an die Zylinder eines Motors vorgesehen ist, um einen ausgeglichenen Fluss sicherzustellen. Ein Befestigungsflansch für einen Ansaugverteiler umfasst eine Fläche mit einem gemeinsamen Netzwerk an Strömungsleitungen, die durch Vertiefungen zur Vermischung von Kurbelgehäusegasen und Ablassdämpfen gebildet werden. Ein weiteres separates, abgedichtetes Netzwerk an Vertiefungen lenkt die Abgase. Darüber hinaus ist ein zusätzliches an der Flanschfläche gebildetes Netzwerk an Vertiefungen vorgesehen, welches einen Hilfsluftstrom zu den Einspritzöffnungen lenkt.International Patent Application WO97 / 34081 discloses a relatively complicated process wherein a flange is provided for distributing vapors or gases to the cylinders of an engine to ensure balanced flow. An intake manifold mounting flange includes a surface having a common network of flow conduits formed by recesses for mixing crankcase gases and exhaust vapors.

In addition, an additional network of depressions formed on the flange surface is provided, which directs an auxiliary air flow to the injection openings.

Das US-Patent 5, 353,752 offenbart ein Ansaugsystem für eine Verbrennungskraftmaschine. Das Ansaugsystem umfasst vier Abzweigrohre, die mit einem vor- und nachgeschaltete Abschnitte aufweisenden Ansaugverteiler in Verbindung stehen. Der nachgeschaltete Abschnitt ist bei vier Einspritzern zur Einspritzung von Kraftstoff an jeden Zylinder angeordnet und über Dichtungen an den Zylinderblock angeschlossen.US Patent 5,353,752 discloses an intake system for an internal combustion engine. The intake system comprises four branch pipes, which communicate with an upstream and downstream sections having intake manifold. The downstream section is located at each injector for injection of fuel to each cylinder and connected via seals to the cylinder block.

Aufgabe der Erfindung ist die effektivere Isolierung eines Ansaugverteilers von durch den Motorbetrieb verursachten Schwingungen.The object of the invention is the more effective isolation of an intake manifold from vibrations caused by engine operation.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is solved by the characterizing features of claim 1.

Erfindungsgemäß ermöglicht die Anschlussplatte, dass der Ansaugverteiler schwingungsmäßig von dem Motor isoliert ist, dadurch, dass Zulaufkanäle oder Rohre des Ansaugverteilers innerhalb der Öffnungen an der Anschlussplatte gesichert werden können.According to the invention, the port plate allows the intake manifold to be vibrationally isolated from the engine by allowing intake ports or pipes of the intake manifold to be secured within the ports on the port plate.

Die Befestigungsvorrichtung gemäß der vorliegenden Erfindung umgeht daher die Notwendigkeit von Klebeverbindungen, Befestigungsflanschen und Flanschschrauben zur Befestigung des Ansaugverteilers an den Motor. In der Vergangenheit haben derartige Befestigungsflansche verursacht, dass Motorschwingungen auf den Ansaugverteiler übertragen wurden. Darüber hinaus wird aufgrund des Verzichtes auf Befestigungsflansche ein Ansaugverteiler geschaffen, welcher relativ einfach in der Herstellung ist und sich leicht am Zylinderkopf befestigen lässt.The fastening device according to the present invention therefore obviates the need for adhesive joints, mounting flanges and flange bolts for attaching the intake manifold to the engine. In the past, such mounting flanges have caused engine vibrations to be transmitted to the intake manifold. In addition, due to the absence of mounting flanges an intake manifold is provided which is relatively easy to manufacture and can be easily attached to the cylinder head.

Gemäß der Ausführung der vorliegenden Erfindung ist es möglich, dass der Sicherungsmechanismus, welcher zwischen den Zulaufkanälen oder Rohren des Ansaugverteilers und der glatten Flächen der Öffnungen an der Anschlussplatte angeordnet ist, einen O-Ring zur wirksamen Isolierung von Schwingungen aufweist.According to the embodiment of the present invention, it is possible for the securing mechanism, which is disposed between the intake ports or pipes of the intake manifold and the smooth surfaces of the openings on the port plate, to have an O-ring for effectively isolating vibrations.

Gemäß wiederum einem weiteren bevorzugten Ausführungsbeispiel der vorliegenden Erfindung ist ein Abschnitt des Ansaugverteilers über Ösen an einer Ventilabdeckung angebracht, um den Ansaugverteiler zusätzlich von Motorschwingungen während des Betriebes zu isolieren und den Ansaugverteiler zuverlässig zu befestigen.According to yet another preferred embodiment of the present invention, a portion of the intake manifold is attached via eyelets to a valve cover to additionally insulate the intake manifold from engine vibration during operation and to reliably secure the intake manifold.

Weitere Aufgaben, Vorteile und neuheitliche Merkmale der vorliegenden Erfindung werden anhand der nachfolgenden Beschreibung der Erfindung ersichtlich und im Zusammenhang mit den beigefügten Zeichnungen näher erläutert.Other objects, advantages and novel features of the present invention will become apparent from the following description of the invention and further illustrated in conjunction with the accompanying drawings.

AUSFÜHRLICHE BESCHREIBUNG DER ZEICHNUNGENDETAILED DESCRIPTION OF THE DRAWINGS

In Figur 1 ist eine Befestigungsvorrichtung 1 gemäß der vorliegenden Erfindung dargestellt. Wie gezeigt, kann Befestigungsvorrichtung 1 eingesetzt werden, um einen Ansaugverteiler 2 an einen Motor 8 über eine Anschlussplatte 12 anzuschließen.FIG. 1 shows a fastening device 1 according to the present invention. As shown, fastening device 1 can be used to connect an intake manifold 2 to a motor 8 via a connection plate 12.

Der Ansaugverteiler 2 ist mehrteilig ausgeführt und beinhaltet beispielsweise eine untere Schale 4, welche mit einer mittleren Schale 6 bzw. einer oberen Schale 7 verbunden werden kann. Die untere Schale 4 ist mit einer Vielzahl von Rohren oder Zulaufkanälen 5 versehen, welche in der Lage ist, den übrigen Ansaugverteiler 2 zu halten. Es wird jedoch auch darauf hingewiesen, dass der Ansaugverteiler 2 aus einem Stück aufgebaut werden kann, ohne vom Rahmen der Erfindung abzuweichen.The intake manifold 2 is designed in several parts and includes, for example, a lower shell 4, which can be connected to a middle shell 6 and an upper shell 7. The lower shell 4 is provided with a plurality of tubes or inflow channels 5 which is capable of holding the remaining intake manifold 2. However, it is also to be understood that the intake manifold 2 may be constructed in one piece without departing from the scope of the invention.

Die Befestigungsvorrichtung 1 umfasst eine Anschlussplatte 12, welche fest an den Zylinderkopf 10 des Motors 8 angeschlossen ist. Diese sichere Anbringung der Anschlussplatte 12 an Motor 8 kann über Schrauben oder Schnappverschlüsse vorgesehen werden oder auch über jede beliebige Anschlussvorrichtung, welche die Anschlussplatte 12 an Zylinderkopf 10 sicher hält. Die Anschlussplatte 12 ist mit einer Anzahl von Öffnungen 14 versehen, die der Anzahl und der Form der Rohre 5 des Ansaugverteilers 2 entspricht.The fastening device 1 comprises a connection plate 12, which is firmly connected to the cylinder head 10 of the motor 8. This secure attachment of the connection plate 12 to the motor 8 can be provided by means of screws or snap closures or via any connection device which securely holds the connection plate 12 on the cylinder head 10. The terminal plate 12 is provided with a number of openings 14, which corresponds to the number and shape of the tubes 5 of the intake manifold 2.

Gemäß Figur 2 wird eine Nahaufnahme der hier vorliegenden erfindungsgemäßen Befestigungsvorrichtung 1 dargestellt. Wie zu sehen, ist jedes Ansaugrohr 5 in einer entsprechenden Öffnung 14 der gesicherten Anschlussplatte 12 eingesetzt. Um die Rohre 5 des Ansaugverteilers 2 mit der Anschlussplatte 12 sicher zu halten, sind O-Ringe (17) dazwischen angebracht. Die Öffnungen 14 von Anschlussplatte 12 weisen glatte Oberflächen auf, an denen O-Ringe (17) sitzen können. Dementsprechend ermöglicht Anschlussplatte 12 der erfindungsgemäßen Befestigungsvorrichtung 1, dass der Ansaugverteiler 2 am Zylinder 10 montiert werden kann, ohne Klebeverbindungen, Befestigungsflansche bzw. Flanschschrauben einzusetzen.According to FIG. 2, a close-up of the fastening device 1 according to the present invention is shown. As can be seen, each intake pipe 5 is inserted in a corresponding opening 14 of the secured connection plate 12. In order to securely hold the tubes 5 of the intake manifold 2 with the terminal plate 12, O-rings (17) are interposed therebetween. The openings 14 of terminal plate 12 have smooth surfaces on which O-rings (17) can sit. Accordingly, connection plate 12 of the fastening device 1 according to the invention allows the intake manifold 2 can be mounted on the cylinder 10 without using adhesive connections, mounting flanges or flange bolts.

Um den Ansaugverteiler 2 zu formen, kann die obere Schale 7 an der unteren Schale 4 befestigt werden. Darüber hinaus kann die obere Schale 7 Befestigungsflansche 15 aufweisen, um diese obere Schale an einer Ventilabdeckung (nicht dargestellt) am Motor 8 über isolierende Befestigungsösen 16 zu befestigen.To form the intake manifold 2, the upper shell 7 can be fixed to the lower shell 4. In addition, the upper shell 7 may have attachment flanges 15 for securing this upper shell to a valve cover (not shown) on the engine 8 via insulating attachment eyes 16.

Demgemäß ermöglicht die Befestigungsvorrichtung 1 der vorliegenden Erfindung, den Ansaugverteiler 2 im wesentlichen von durch den Betrieb des Motors verursachten Schwingungen zu isolieren, die in der Vergangenheit durch die Befestigungsflansche auf den Ansaugverteiler 2 übertragen wurden.Accordingly, the fastening device 1 of the present invention enables the intake manifold 2 to be substantially isolated from vibrations caused by the operation of the engine, which have in the past been transmitted to the intake manifold 2 through the mounting flanges.
