Description

Turbolader turbocharger
Beschreibungdescription
Die Erfindung betrifft einen Turbolader gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a turbocharger according to the preamble of claim 1.
Ein gattungsgemäßer Turbolader ist aus der US 6,205,784 Bl bekannt .A generic turbocharger is known from US 6,205,784 Bl.
Bei derartigen Turboladern wurde bisher das Ladedruckregelventil (LDR) über ein Halteblech mit 3 Schläuchen an das Ventilgehäuse angebunden und das elektrische Schubumluftventil (ESUV) mit Schrauben separat am Ventilgehäuse angeflanscht. Diese Anordnung erfordert aufwendige Schlauchführungen und einen erhöhten Montageaufwand aufgrund der Vielzahl der Bauteile. Ferner ist dadurch eine erhöhte Störungsanfälligkeit der Gesamtanordnung bzw. Regelkreise gegeben.In turbochargers of this type, the charge pressure control valve (LDR) was previously connected to the valve housing via a holding plate with 3 hoses, and the electrical diverter valve (ESUV) was flange-mounted separately on the valve housing with screws. This arrangement requires expensive hose guides and increased assembly costs due to the large number of components. Furthermore, an increased susceptibility to failure of the overall arrangement or control circuits is given.
Es ist demgegenüber Aufgabe der vorliegenden Erfindung, einen Turbolader für einen Verbrennungsmotor gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, der einen vereinfachten Aufbau aufweist bzw. eine rationellere Fertigung des Ladedruckregelventils und des elektrischen Schubumluftventils ermöglicht.It is accordingly an object of the present invention to provide a turbocharger for an internal combustion engine according to the preamble of claim 1, which has a simplified structure and allows a more rational production of the wastegate and the electric diverter valve.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1 bzw. 2.The solution of this object is achieved by the features of claim 1 and 2, respectively.
So ist es bei der erfindungsgemäßen Ausbildung des Turboladers möglich, das Ladedruckregelventil (LDR) auf das elektrische Schubumluftventil (ESUV) aufzusetzen und dadurch eine Wirkverbindung dieser Ventilanordnung ohne Schlauchverbindung direkt herzustellen. Somit kann eine einfachere Ventilanordnung durch Verbindung des Schubumluftventils (ESUV) und des Ladedruckregelventils (LDR) (also ein kombiniertes LDRESUV) geschaffen und die Anzahl der benötigten Bauteile gegenüber der bisherigen Bauform reduziert werden.So it is possible in the inventive design of the turbocharger, the wastegate (LDR) on the electric diverter valve (ESUV) set up and thereby establish an operative connection of this valve assembly without hose connection directly. Thus, a simpler valve assembly by connecting the diverter valve (ESUV) and the wastegate (LDR) (ie, a combined LDRESUV) created and the number of components required compared to the previous design can be reduced.
Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The dependent claims have advantageous developments of the invention to the content.
In Anspruch 7 ist eine erfindungsgemäße Ventilanordnung als selbstständig handelbares Objekt definiert.In claim 7, a valve assembly according to the invention is defined as a self-negotiable object.
Anspruch 8 beinhaltet eine vorteilhafte Weiterbildung der Ventilanordnung gemäß Anspruch 7.Claim 8 includes an advantageous development of the valve assembly according to claim 7.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich aus nachfolgender Beschreibung eines Ausführungsbeispiels und der Zeichnung.Further details, advantages and features of the invention will become apparent from the following description of an embodiment and the drawing.

Fig. 3 eine erfindungsgemäße Ventilanordnung im montierten Zustand.Fig. 3 shows a valve assembly according to the invention in the assembled state.
In Fig. 1 ist eine erfindungsgemäße Turboladeranordnung 1 schematisch dargestellt.In Fig. 1, a turbocharger assembly 1 according to the invention is shown schematically.
Der Turbolader 1 weist einen Verdichter 2 mit einem Verdichtergehäuse 3 auf.The turbocharger 1 has a compressor 2 with a compressor housing 3.
Am Verdichtergehäuse 3 des Verdichters 2 ist ein Schubumluftventil 4 mit einem Ventilgehäuse 6 befestigt. Ein Ladedruckregelventil 5 ist am Ventilgehäuse 6 des Schubumluftventils 4 befestigt. Über eine Schlauchverbindung 9 ist ein Aktuatoraus- gang 8 des Ladedruckregelventils 5 mit einem Aktuator 10 verbunden.On the compressor housing 3 of the compressor 2, a diverter valve 4 is attached to a valve housing 6. A wastegate 5 is attached to the valve housing 6 of the diverter valve 4. Via a hose connection 9, an actuator outlet 8 of the wastegate 5 is connected to an actuator 10.
Alle sonstigen üblichen Bauteile der Turboladeranordnung 1 sind hier nicht näher bezeichnet, da sie für die Beschreibung der Erfindung nicht von Belang sind.All other conventional components of the turbocharger assembly 1 are not specified here, as they are not relevant to the description of the invention.
In Fig. 2 ist eine Prinzipdarstellung des mit dem Schubumluftventil 4 verbundenen Ladedruckregelventils 5 dargestellt. Wie aus dieser Fig. 2 ersichtlich, ist das Ladedruckregelventil 5, das einen Aktuatorabgang 8, einen Anschlussstecker 12 für eine elektrische Verbindung sowie einen Abgang Pl aufweist, auf das Gehäuse 6 des Schubumluftventils 4 aufgesetzt. Durch diese Anordnung wird eine Wirkverbindung des in einem Innendruckraum 7 des elektrischen Schubumluftventils 4 herrschenden kompensierten Drucks P2 mit dem Ladedruckventil 5 zwischen diesen Komponenten ohne zusätzliche Verbindungselemente, z. B. eine Schlauchverbindung, direkt hergestellt. Weiterhin ist vorstellbar, dass der Druckanschluss Pl, der als Entlüftung des Ventils dient, innerhalb des Ventilgehäuses verläuft und direkt mit der Verdichtergehäusesaugseite ohne Verwendung einer separaten Leitung verbunden ist.In Fig. 2 is a schematic diagram of the associated with the diverter valve 4 waste gate valve 5 is shown. As can be seen from this FIG. 2, the wastegate 5, which has a Aktuatorabgang 8, a connector 12 for an electrical connection and an outlet Pl, placed on the housing 6 of the diverter valve 4. By this arrangement, an operative connection of the prevailing in an internal pressure chamber 7 of the electric diverter valve 4 compensated pressure P2 with the wastegate 5 between these components without additional connecting elements, for. B. a hose connection, made directly. Furthermore, it is conceivable that the pressure port Pl, as the vent of the Valve, runs inside the valve housing and is directly connected to the compressor housing suction side without the use of a separate line.
Fig. 3 ist eine Darstellung des Verdichters 2 mit der erfindungsgemäßen Ventilanordnung 11 gezeigt. Aus dieser Abbildung sind das direkt mit dem Ladedruckventil 5 verbundene Schubumluftventil 4 sowie eine zu einem Aktuator 10 führende Schlauchverbindung 9 ersichtlich.FIG. 3 shows an illustration of the compressor 2 with the valve arrangement 11 according to the invention. From this figure, the directly connected to the boost pressure valve 5 Schubumluftventil 4 and leading to an actuator 10 hose connection 9 can be seen.
Durch die erfindungsgemäße Ventilanordnung 11 wird die Anzahl der erforderlichen Bauteile zumindest um einen Schlauch mit den dazugehörigen Schlauchklemmen und die Halterung für das bisher separat am Verdichtergehäuse 3 befestigte Ladedruckregelventil 5 samt den dazugehörigen Befestigungsschrauben reduziert. Dies führt zu einem reduzierten Montage- und Zeitaufwand bei der Fertigung sowie zu damit verbundenen verringerten Kosten. Desweiteren ist eine zusätzliche Einsparung möglich, indem die elektrischen Anschlüsse von Ladedruckregelventil und Schubumluftventil zu einem Anschluss zusammengefasst werden.By the valve assembly 11 according to the invention, the number of required components is at least reduced by a hose with the associated hose clamps and the holder for the previously separately attached to the compressor housing 3 wastegate 5 together with the associated mounting screws. This leads to a reduced assembly and time expenditure in the production and associated reduced costs. Furthermore, an additional saving is possible by the electrical connections of wastegate and diverter valve are combined to form a connection.
