Description
Technisches GebietTechnical area
Die Erfindung betrifft einen Notöltank für Abgasturbolader, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a emergency oil tank for exhaust gas turbocharger, according to the preamble of
Stand der TechnikState of the art
Die Schmierstellen eines Abgasturboladers werden zumeist mit dem Schmieröl der mit diesem verbundenen Brennkraftmaschine versorgt. Um beim Ausfall der Schmierölversorgung der Brennkraftmaschine eine Havarie des Abgasturboladers zu verhindern, muss der zunächst mit hoher Drehzahl weiterlaufende Abgasturbolader noch für eine bestimmte Zeit mit Schmieröl versorgt werden. Dazu ist am oder im Gehäuse des Abgasturboladers ein Notöltank vorgesehen, welcher entweder im Hauptstrom oder im Nebenstrom, d. h. in Reihe oder parallel zu den Schmierstellen des Abgasturboladers angeordnet ist.The lubrication points of an exhaust gas turbocharger are usually supplied with the lubricating oil of the associated with this internal combustion engine. In order to prevent a failure of the exhaust gas turbocharger in case of failure of the lubricating oil supply to the internal combustion engine, the exhaust gas turbocharger, which initially continues at high speed, must be supplied with lubricating oil for a certain time. For this purpose, a Notöltank is provided on or in the housing of the exhaust gas turbocharger, which either in the main stream or in the secondary stream, d. H. is arranged in series or parallel to the lubrication points of the exhaust gas turbocharger.
Aus der Firmenschrift MET 83SD Turbocharger Overhaul Procedure, Januar 1996 von Mitsubishi Heavy Industries, Ltd., S. 4, ist ein solcher Abgasturbolader mit einem im Lagergehäuse angeordneten Notöltank bekannt. Der Notöltank liegt im Hauptstrom und wird über eine Rückschlagklappe sowie eine am Notöltank angeschlossene Zuführleitung mit Öl versorgt. Zudem wird der Notöltank mittels einer Entlüftungsleitung belüftet bzw. entlüftet, welche an ihrem einen, in den Notöltank eingreifen Ende eine Drosselbohrung aufweist und mit ihrem anderen Ende in einen Freiraum des Lagergehäuses mündet.From the company publication MET 83SD Turbocharger Overhaul Procedure, January 1996 by Mitsubishi Heavy Industries, Ltd., p. 4, such an exhaust gas turbocharger with an arranged in the bearing housing emergency oil tank is known. The emergency oil tank is located in the main stream and is supplied with oil via a non-return valve and a supply line connected to the emergency oil tank. In addition, the emergency oil tank is ventilated by means of a vent line and vented, which at its one, in the emergency oil tank end has a throttle bore and opens with its other end into a free space of the bearing housing.
Aufgrund der Anordnung der Rückschlagklappe im Hauptstrom des Schmieröls tritt in der Zuführleitung ein gewisser Druckverlust ein. Dadurch muss die Ölzufuhr entweder grösser dimensioniert werden, als dies eigentlich nötig ist oder die Lager des Abgasturboladers können nicht optimal mit Schmieröl versorgt werden.Due to the arrangement of the check valve in the main flow of the lubricating oil, a certain pressure loss occurs in the supply line. As a result, the oil supply must either be dimensioned larger than is actually necessary or the bearings of the exhaust gas turbocharger can not be optimally supplied with lubricating oil.
Zudem birgt die Anordnung eines solchen Stellelementes im Hauptstrom des Schmieröls latent die Gefahr einer Behinderung der Ölzufuhr bei einer eventuell auftretenden Störung in der Funktion dieses Stellelementes.In addition, the arrangement of such an actuating element in the main flow of the lubricating oil latently carries the risk of obstruction of the oil supply in the event of a malfunction occurring in the function of this control element.
Darstellung der ErfindungPresentation of the invention
Die Erfindung versucht alle diese Nachteile zu vermeiden. Ihr liegt die Aufgabe zugrunde, einen im Lagergehäuse eines Abgasturboladers angeordneten Notöltank mit einer verbesserten Schmierölzufuhr zu schaffen.The invention seeks to avoid all these disadvantages. It is the object of the invention to provide a arranged in the bearing housing of an exhaust gas turbocharger emergency oil tank with an improved lubricating oil supply.
Erfindungsgemäß wird dies dadurch erreicht, dass bei einer Vorrichtung gemäß dem Oberbegriff des Anspruchs 1, zusätzlich zu einer Drosselbohrung ein ebenfalls in den Notöltank mündendes Rückschlagventil in der Entlüftungsleitung angeordnet ist.According to the invention this is achieved in that in a device according to the preamble of
Beim Ausfall der über die Zuführleitung erfolgenden Schmierölversorgung wird die sich in der Zuführleitung zurückziehende Ölsäule über die in der Entlüftungsleitung angeordnete Drosselbohrung und über das erfindungsgemäß ebenfalls in der Entlüftungsleitung befindliche Rückschlagventil belüftet. Damit entfällt die Notwendigkeit der Anordnung eines Rückschlagventils in der Zuführleitung, d. h. im Hauptstrom. Aufgrund dessen ist bei der Schmierölversorgung ein geringerer Druckverlust zu verzeichnen. Letztlich kann dadurch eine verbesserte Schmierölzufuhr erreicht werden. Zudem kann die Schmierölversorgung durch den Wegfall des Rückschlagventils in der Zuführleitung sicherer und kostengünstiger realisiert werden.In the event of failure of the lubricating oil supply taking place via the supply line, the oil column, which retracts in the supply line, is ventilated via the throttle bore arranged in the vent line and via the non-return valve likewise located in the vent line according to the invention. This eliminates the need for the arrangement of a check valve in the supply line, d. H. in the main stream. Due to this, the lubricating oil supply has a lower pressure loss. Ultimately, this can be achieved an improved lubricating oil supply. In addition, the lubricating oil supply can be realized safer and cheaper by eliminating the check valve in the supply line.
Besonders vorteilhaft ist das Rückschlagventil im obersten Bereich der Entlüftungsleitung angeordnet. Auf diese Weise kann eine einfache Kombination der Drosselbohrung und des Rückschlagventils in einem einzigen Bauteil realisiert werden, wodurch geringere Herstellungskosten entstehen.Particularly advantageously, the check valve is arranged in the uppermost region of the vent line. In this way, a simple combination of the throttle bore and the check valve can be realized in a single component, resulting in lower manufacturing costs.
Schließlich wird mit Vorteil der Schmierölbehälter einer mit dem Abgasturbolader verbundenen Brennkraftmaschine als außerhalb des Abgasturboladers angeordnetes Schmierölreservoir verwendet.Finally, it is advantageous to use the lubricating oil container of an internal combustion engine connected to the exhaust gas turbocharger as a lubricating oil reservoir arranged outside of the exhaust gas turbocharger.
