Description
Lade- und Kühl-Turboaggregat für Verbrennungsmotoren Gegenstand der Erfindung ist ein Lade- und Kühl-Turboaggregat, das dadurch gekennzeichnet ist, dass jedes von beiden Schaufelrädern einer zwei stufigen Turbine frei drehbar ist, eines von ihnen mit dem Schaufelrad des Ladegebläses, das andere mit dem Schaufelrad des Kühllüfters verbunden ist, wobei zwischen beiden Stufen der Turbine ein Rege lungsablass angeordnet ist.
Es sind bereits Konstruktionen von Turbogebläsen für die Aufladung von Kolbenverbrennungsmotoren bekannt, und es wurden bereits Abgasturbinen ent worfen, die den Lüfter für die Kühlung von Kolben motoren antreiben. Diese Einrichtungen sind ener getisch vorteilhaft, da sie Energie der Abgase zur Erhöhung der Motornutzleistung ausnützen und somit den thermischen Wirkungsgrad erhöhen.
Durch geeignete Anordnung des Turbogebläses und des Turbolüfters in ein Ganzes kann eine Ein richtung erreicht werden, die hinsichtlich Abmessun gen kleiner und fabrikatonisch billiger als zwei selb ständige Einheiten sind. Eine konstruktive Lösung nach Erfindung ist in beigeschlossener Figur bei spielsweise veranschaulicht. Aus der Figur ist er sichtlich, dass die Abgase in das Turbinengehäuse 1 der ersten zentripetaldurchströmten Stufe 2 beim Eintrittsstutzen 3 eintreten. Auf der Turbinenwelle ist am Ende das Schaufelrad 4 des Zentrifugal gebläses befestigt, das die Ladeluft in die Zylinder des Kolbenverbrennungsmotors liefert.
Zwischen der ersten und zweiten Stufe der Turbine sind Leitschau- fein 6, die die Gase in das Rad der zweiten zentri- fugaldurchströmten Stufe 5 leiten. Am linken Wellen ende der Stufe 5 ist das Lüfterrad 7 befestigt, das Kühlluft für den Verbrennungskolbenmotor liefert. Das Zwischengehäuse mit den Leitschaufeln 6 kann so ausgebildet werden, dass man einen Teil der Gase vor Eintritt in die Stufe 5 ablassen kann.
Diese Einrichtung ist hinsichtlich Abmessungen klein, und man kann sie vorteilhaft zwischen die Zylinder eines Motors mit V-Anordnung anbringen. Ein weiterer Vorteil der beschriebenen Zweiwellen- Anordnung beruht darin, dass das Trägheitsmoment eines Rotors verhältnismässig gering ist, was vorteil haft ist im Hinblick auf die Fähigkeit der Einrich tung, rasch auf die Änderungen in der Motorbela stung zu reagieren.
Wenn auch in der Figur zwei radiale Stufen gezeichnet sind, so kann die vorge schlagene Anordnung in manchen Fällen entweder mit axialer und radialer Stufe oder mit zwei axialen Stufen ausgeführt werden.
Charging and cooling turbo unit for internal combustion engines The subject of the invention is a charging and cooling turbo unit, which is characterized in that each of the two paddle wheels of a two-stage turbine is freely rotatable, one of them with the paddle wheel of the supercharger, the other with the impeller of the cooling fan is connected, with a Rege treatment outlet is arranged between the two stages of the turbine.
There are already constructions of turbo blowers for charging reciprocating internal combustion engines known, and exhaust gas turbines have already been designed that drive the fan for cooling piston engines. These facilities are energetically advantageous because they use the energy of the exhaust gases to increase the engine power and thus increase the thermal efficiency.
By suitable arrangement of the turbo blower and the turbo fan as a whole, a device can be achieved that are smaller and cheaper than two independent units in terms of dimensions. A structural solution according to the invention is illustrated in the enclosed figure for example. It can be seen from the figure that the exhaust gases enter the turbine housing 1 of the first centripetal flow-through stage 2 at the inlet connector 3. At the end of the turbine shaft, the impeller 4 of the centrifugal fan is attached, which delivers the charge air into the cylinders of the reciprocating internal combustion engine.
Between the first and second stage of the turbine there are guide showers 6, which guide the gases into the wheel of the second stage 5 through which centrifugal flow occurs. At the left shaft end of the stage 5, the fan wheel 7 is attached, which supplies cooling air for the internal combustion piston engine. The intermediate housing with the guide vanes 6 can be designed in such a way that some of the gases can be released before entering the stage 5.
This device is small in size and can advantageously be placed between the cylinders of a V-shaped engine. Another advantage of the described two-shaft arrangement is that the moment of inertia of a rotor is relatively low, which is advantageous with regard to the ability of the device to react quickly to changes in the engine load.
If two radial stages are drawn in the figure, the proposed arrangement can in some cases be carried out with either an axial and radial stage or with two axial stages.
