Abstract
Description
Die Neuerung bezieht sich auf eine Vorrichtung zur Steuerung einer Abgaszuführung für Abgasturbolader mit Axialturbinen zur Aufladung von Brennkraftmaschinen, wobei ein Abgaszuführgehäuse mit zwei koaxial angeordnete, durch eine konzentrische Zwischenwand gebildete Zuführkanäle zur lastabhängig einstellbaren Beaufschlagung des Turbinenleitring-Anströmquerschnitts mittels eines axial verschiebbaren Steuerschiebers für einen inneren Zuführkanal.The Innovation relates to a device for controlling an exhaust gas supply for exhaust gas turbochargers with axial turbines for charging internal combustion engines, wherein a Exhaust gas supply housing with two coaxially arranged, through a concentric partition wall formed supply channels for load-dependent adjustable Actuation of the Turbinenleitring Anströmquerschnitts by means of a axially displaceable spool for an inner feed channel.
Es
ist aus der
Bei diesen Anordnungen bestehen die Mängel, daß ein relativ hoher Aufwand für die Steuerung der Zuführkanäle mit einem zusätzlichen Raumbedarf besteht. Ferner ist es relativ schwer, eine in der Praxis erforderliche, um 90 Grad gekrümmte Abgaszuführung einzusetzen. Weiterhin ist es nur beschränkt möglich, eine ungestörte und damit eine verlustarme Zuströmung der Abgase zu ermöglichen.at These arrangements are the shortcomings that a relatively high cost for the Control of the feed channels with a additional Space requirement exists. Furthermore, it is relatively difficult, one in practice required, curved by 90 degrees exhaust gas supply use. Furthermore, it is only possible to an undisturbed and limited thus a low-loss inflow allow the exhaust gases.
Die Aufgabe der Neuerung ist es, eine kompakte Anordnung für die Einbringung in ein Gaszuführgehäuse zu schaffen, die eine verlustarme Zuströmung der Abgase zur Turbine als strömungsgünstige Ausbildung für beide Betriebszustände bei der Steuerung der Zuführkanäle ermöglicht.The The object of the innovation is to provide a compact arrangement for the introduction to create a gas supply housing, the one low-loss inflow the exhaust gases to the turbine as aerodynamic training for both operating conditions in the control of the feed channels allows.
Die Lösung dieser Aufgabe erfolgt neuerungsgemäß dadurch, daß die Zuführkanäle im Abgaszuführgehäuse angeordnet sind und ein Verschlußelement im Anströmbereich in der Art einer Kugelkalotte als Strömungsführungselement in einer Position den inneren Zuführkanal verschließt und in der anderen Position zur Freigabe des inneren Zuführkanals in das Zentrum des Abgaszuführgehäuses über innenliegende Stellmittel nach innen verschiebbar ist.The solution This object is achieved according to renewal in that the supply channels arranged in the Abgaszuführgehäuse are and a closure element in the inflow area in the manner of a spherical cap as a flow guide element in one position the inner feed channel closes and in the other position for releasing the inner feed channel in the center of the Abgaszuführgehäuses over internal Adjusting means is displaced inwards.
Hierdurch besteht der Vorteil einer kompakten Anordnung zur Integration und Nachrüstung im Abgaszuführgehäuse. Gleichzeitig wird durch die Ausbildung eine strömungsgünstige Zuführung der Abgase in beiden Positionen erreicht.hereby There is the advantage of a compact arrangement for integration and retrofitting in the exhaust gas supply housing. simultaneously By training a streamlined supply of exhaust gases in both Reached positions.
Eine vorteilhafte Ausgestaltung zur Strömungsführung wird dadurch geschaffen, daß die Zuführkanäle in Strömungsrichtung der Abgasführung rotationssymmetrisch zum Leitring der Turbine geführt sind.A advantageous embodiment for flow guidance is created by that the Feed channels in the flow direction the exhaust system rotationally symmetrical led to the guide ring of the turbine are.
Ferner wird vorgeschlagen, daß das Stellmittel für das Verschlußelement als im Abgaszuführgehäuse angeordneter Pneumatikzylinder mit nach außen geführten Steuerleitungen ausgebildet ist.Further It is suggested that the Adjusting means for the closure element as arranged in the Abgaszuführgehäuse Pneumatic cylinder with outward out Control lines is formed.
In der Zeichnung sind Ausführungsbeispiele der Neuerung schematisch dargestellt. Es zeigen:In the drawing are embodiments of Innovation shown schematically. Show it:
