Definitions
- the invention relates to a cooling system for motor vehicles with the features of Preamble in claim 1.
- the cooling system is in the as yet unpublished German application DE 199 50 755.4, but also in a number of other publications (EP 1 045 217 A1) have been described. In the unpublished application, the same Applicant heard, it is about increasing the efficiency of the cooling system improve what is there by an optimized position of the radial impeller inside the cooling system is reached.
- the cooling systems of the type described in the preamble are fundamentally more efficient than conventional cooling systems with one behind the other in the direction of cooling air flow arranged individual coolers, because in the cooling systems of the type described Centrifugal fans can be used.
- the cooling system for motor vehicles the question of efficiency from the point of view of the overall energy balance of the vehicle.
- the mostly electric or fan driven directly by the motor that blocks the flow of cooling air through the cooling network the cooler sucks through, is only put into operation when necessary.
- the dynamic pressure is sufficient to provide sufficient cooling capacity to make available because of the larger in conventional cooling systems
- Cross section allows a relatively high volume flow of cooling air.
- a box-shaped cooling system in which the Cooling network surface of one of the coolers arranged on the outside of the cooler Sliding blind can be covered or opened to increase the volume flow to be able to vary the cooling network area of the other coolers as required.
- the object of the present invention is to determine the volume flow Increase cooling air in dynamic pressure operation of the cooling system without the effectiveness of Radial fan significantly impair during its operating phases.
- the cooling system of the motor vehicle can thus work in a back pressure operation over a larger operating range, d. H. without that Radial fan to start up, which means less energy is required.
- the start-up frequency and the on-time of the radial fan were determined by the Invention reduces, which also leads to reduced fuel consumption.
- the openings have covers (closure elements) that how check valves work. This effect can easily be achieved through the Arrangement of rubber tabs on the inside of the front wall can be achieved which are opened by the dynamic pressure when the centrifugal fan is not in operation is. If the radial fan is in operation, it ensures that it is inside the cooling system there is pressure to keep the covers closed.
- the covers are above or to the side of the openings and preferably on the inside attached to the front wall.
- closure elements and mechanisms are the subject of claims 5 to 9. These are around flexible or rigid closure elements which can be moved by means of suitable mechanisms, via signals - for example together with the commissioning or Switching off the radial fan - can be controlled or moved.
- Such locking mechanisms are generally somewhat more complex. However, they can be functional Have advantages that consist, for example, in low noise or in that the openings are more closable, so that the escape of unused cooling air in the operational phases of the radial fan is as complete as possible is prevented.
- Movable via driven rollers Covers or the like go for example from DE-OS 25 01 013 out.
- DE-OS a roller belt filter is used by means of the roller drive there moved, but the roller drive shown there itself is also present Context suitable.
- the reference to these documents is intended to be a more detailed one Replace representation.
- the cover can be made entirely of flexible material exist or only be flexible in the area that can be wound up or unwound, whereby the cover itself can be a rigid plate, which in by means of the roller drive upper and lower guides, which are arranged on the front panel, movable which opens or closes the openings.
- the shape, number and arrangement of the openings in the front wall can be any and depends on how large the additional volume flow should be, how it should distribute which locking elements and locking mechanisms selected are, of course, also in terms of strength and stability, if the front wall serves as a load-bearing element of the cooling system and after other structural or functional restrictions.
- Fig. 1 perspective view of the front wall of the cooling system
- Fig. 2 vertical section along the line II - II in Fig. 1;
- Fig. 3 vertical section along the line III - III in Fig. 1;
- the cooling system consists of water coolers 1 arranged on the right and left ; 2 and an intercooler 3 arranged at the top and is intended for heavy motor vehicles.
- the cooling network 20 of the charge air cooler 3 is significantly greater in its block depth 30 than the block depth 30 of the water cooler 1; 2.
- the block width has the reference number 31 and is also larger in the charge air cooler 3 than in the water coolers 1; 2. In this embodiment there is no cooler at the bottom.
- the underside is therefore closed by the wall 26 (Fig. 3).
- the rear of the cooling system which is not clearly shown, is closed by a wall.
- the front wall 12 there is an intake opening 11 with a nozzle 10, which in this exemplary embodiment was not arranged centrally in the front wall 12, but was shifted slightly to the upper area.
- the exhaust blades 7 and the rear wall 9 of the impeller of the radial fan 6 can be seen in the suction opening 11 .
- the axis 5 of the radial fan 6 has been identified by a dashed line. In the direction of this axis 5 , the cooling air is sucked in, deflected radially and in the direction of the cooler 1; 2; 3 blown.
- the cooler 1; 2; 3 have a known cooling network 20, consisting of flat tubes 22 with corrugated fins 23 arranged between them , the cooling network 20 being shown in more detail in FIG. 2.
- the flat tubes 22 each extend between the two header boxes 21 of the individual coolers 1; 2; 3, so that they run transversely to the fan axis 5 .
- a total of nine openings 13 are present in the front wall 12 , two openings 13 at the top, one on each side, and the remaining seven openings 13 below the suction opening 11 .
- the front wall 12 is exposed to the wind when the motor vehicle is in motion.
- the openings 13 are essentially rectangular openings, the shape, number and arrangement of the openings 13 not being particularly important.
- the coverable openings 13 or essential parts of the front wall 12 are designed like a grill, that is to say, for example, in the manner of a radiator grill.
- the upper two openings 13 have been drawn in the open state, ie the cover 15 protrudes on one side inwards, so that cooling air flowing in from outside can penetrate through the openings 13 into the interior of the cooling system when the motor vehicle is in motion.
- the lower openings 13 were drawn closed, it being understood that this was drawn for the sake of clarity only.
- all openings 13 are open, and in operation of the radial fan 6 , however, all openings 13 are closed by means of the covers 14 .
- the covers 14 are made of a suitable rubber. They are attached to the inside of the front wall 12 above the openings 13 . The attachment is of course also possible on the outside of the front wall 12 .
- the cover 14 itself must be arranged on the inside of the front wall 12 in this exemplary embodiment.
- the attachment is stable, so that the permanent function of the covers 14 is ensured over the entire period of use of the cooling system.
- a cover 14 can be seen in FIG. 2. 2 shows the cover 14 in a position as it is present in the back pressure operation of the cooling system, but at all openings 13 .
- the covers 14 can also be constructed differently.
- a single cover 14 does not necessarily have to be assigned to each individual opening 13 . Several preferably smaller openings 13 can be closed by means of a single cover 14 .
- FIG. 2 also shows more clearly than FIG. 1 that the charge air cooler 3 also has a larger block width 31 in addition to the larger block depth 30 , so that there is a clear projection 32 of the charge air cooler 3 to the front over the front wall 12 .
- Such measures can best meet the cooling requirements for each individual cooler in a specific application.
- the excess 32 is compensated for by means of a cover plate 25 .
- each opening 13 has an extra cover 14 , which is advantageous in the selected size of the openings 13 because a better seal is expected when the radial fan 6 is in operation. Furthermore, the size of the covers 14 must of course be selected on the one hand so that they cannot get into the radial impeller or be damaged and on the other hand that they can keep the openings 13 sufficiently tightly closed.

Description
Die Erfindung betrifft eine Kühlanlage für Kraftfahrzeuge mit den Merkmalen des
Oberbegriffs im Anspruch 1.The invention relates to a cooling system for motor vehicles with the features of
Preamble in
Die Kühlanlage ist in der noch nicht veröffentlichten deutschen Anmeldung DE 199
50 755.4, aber auch in einer Reihe anderer Veröffentlichungen (EP 1 045 217 A1)
beschrieben worden. In der noch nicht veröffentlichten Anmeldung, die der gleichen
Anmelderin gehört, geht es darum, die Effizienz der Kühlanlage weiter zu
verbessern, was dort durch eine optimierte Position des Radiallaufrades innerhalb
der Kühlanlage erreicht wird.The cooling system is in the as yet unpublished German application DE 199
50 755.4, but also in a number of other publications (
Die Kühlanlagen der im Oberbegriff beschriebenen Art sind grundsätzlich effizienter als konventionelle Kühlanlagen mit in Kühlluftströmungsrichtung hintereinander angeordneten einzelnen Kühlern, weil bei den Kühlanlagen der beschriebenen Art Radialventilatoren eingesetzt werden können. Jedoch sollte, wenn die Kühlanlage für Kraftfahrzeuge vorgesehen ist, die Frage der Effizienz aus der Sicht der Gesamtenergiebilanz des Fahrzeuges betrachtet werden. Der meist elektrisch oder direkt vom Motor angetriebene Ventilator, der den Kühlluftstrom durch das Kühlnetz der Kühler hindurch saugt, wird nur bei Bedarf in Betrieb genommen. In Phasen geringer Kühlungsanforderung reicht der Staudruck aus, um genügend Kühlleistung zur Verfügung zu stellen, weil der bei konventionellen Kühlanlagen größere Querschnitt einen relativ hohen Volumenstrom der Kühlluft zulässt. Hier ist Verbesserungspotential für die Kühlanlagen der gattungsgemäßen Art vorhanden.The cooling systems of the type described in the preamble are fundamentally more efficient than conventional cooling systems with one behind the other in the direction of cooling air flow arranged individual coolers, because in the cooling systems of the type described Centrifugal fans can be used. However, if the cooling system for motor vehicles, the question of efficiency from the point of view of the overall energy balance of the vehicle. The mostly electric or fan driven directly by the motor that blocks the flow of cooling air through the cooling network the cooler sucks through, is only put into operation when necessary. In phases low cooling requirement, the dynamic pressure is sufficient to provide sufficient cooling capacity to make available because of the larger in conventional cooling systems Cross section allows a relatively high volume flow of cooling air. There is room for improvement here available for the cooling systems of the generic type.
Aus der DE 197 24 728 A1 ist eine kastenförmige Kühlanlage bekannt, bei der die Kühlnetzfläche eines der Kühler mittels einer außen am Kühler angeordneten Schiebejalousie abgedeckt oder geöffnet werden kann, um den Volumenstrom auf die Kühlnetzfläche der anderen Kühler nach Bedarf variieren zu können.From DE 197 24 728 A1 a box-shaped cooling system is known, in which the Cooling network surface of one of the coolers arranged on the outside of the cooler Sliding blind can be covered or opened to increase the volume flow to be able to vary the cooling network area of the other coolers as required.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Volumenstrom der Kühlluft im Staudruckbetrieb der Kühlanlage zu erhöhen, ohne die Wirksamkeit des Radialventilators während seiner Betriebsphasen wesentlich zu beeinträchtigen.The object of the present invention is to determine the volume flow Increase cooling air in dynamic pressure operation of the cooling system without the effectiveness of Radial fan significantly impair during its operating phases.
Die erfindungsgemäße Lösung ergibt sich bei der Kühlanlage mit den Merkmalen
des Oberbegriffs im Anspruch 1 durch die in dessen Kennzeichen stehenden
Merkmale. Weitere Merkmale sind Gegenstand der Ansprüche 2 bis 10.The solution according to the invention results in the cooling system with the features
of the preamble in
Durch das Vorsehen von zusätzlichen Öffnungen in der Frontwand, die im Staudruckbetrieb geöffnet und in den Betriebsphasen des Radialventilators geschlossen sind, wird erreicht, dass im Staudruckbetrieb ein größerer Volumenstrom der Kühlluft zur Verfügung steht, der die Kühlwirkung auf die in den Rohren der Kühler strömenden Medien verbessert. Somit kann die Kühlanlage des Kraftfahrzeugs über einen größeren Betriebsbereich im Staudruckbetrieb arbeiten, d. h. ohne den Radialventilator in Betrieb zu nehmen, wodurch weniger Energie benötigt wird. Die Einschalthäufigkeit und die Einschaltdauer des Radialventilators wurden durch die Erfindung reduziert, was ebenfalls zu einem reduzierten Kraftstoffverbrauch führt.By providing additional openings in the front wall, which are in back pressure operation opened and closed in the operational phases of the radial fan are achieved, that a larger volume flow of the Cooling air is available, which has the cooling effect on the pipes in the cooler streaming media improved. The cooling system of the motor vehicle can thus work in a back pressure operation over a larger operating range, d. H. without that Radial fan to start up, which means less energy is required. The The start-up frequency and the on-time of the radial fan were determined by the Invention reduces, which also leads to reduced fuel consumption.
Im einfachsten Fall besitzen die Öffnungen Abdeckungen (Verschlußelemente), die wie Rückschlagventile wirken. Ganz einfach kann diese Wirkung bereits durch die Anordnung von Gummilappen an der Innenseite der Frontwand erreicht werden, die durch den Staudruck geöffnet werden, wenn der Radialventilator nicht in Betrieb ist. Ist der Radialventilator in Betrieb, sorgt der im Inneren der Kühlanlage herrschende Druck dafür, dass die Abdeckungen geschlossen bleiben. Die Abdekkungen sind oberhalb oder seitlich der Öffnungen und vorzugsweise an der Innenseite der Frontwand befestigt.In the simplest case, the openings have covers (closure elements) that how check valves work. This effect can easily be achieved through the Arrangement of rubber tabs on the inside of the front wall can be achieved which are opened by the dynamic pressure when the centrifugal fan is not in operation is. If the radial fan is in operation, it ensures that it is inside the cooling system there is pressure to keep the covers closed. The covers are above or to the side of the openings and preferably on the inside attached to the front wall.
Es können jedoch auch andere Verschlußelemente und Verschlußmechanismen
zum Einsatz kommen, die den gleichen Zweck erfüllen. Solche Verschlußelemente
und Mechanismen sind Gegenstand der Ansprüche 5 bis 9. Es handelt sich dabei
um mittels geeigneter Mechanismen bewegbare flexible oder steife Verschlußelemente,
die über Signale - beispielsweise gemeinsam mit der Inbetriebsetzung oder
Abschaltung des Radialventilators - gesteuert bzw. bewegt werden. Solche Verschlußmechanismen
sind generell etwas aufwendiger. Sie können jedoch funktionelle
Vorteile besitzen, die beispielsweise in der Geräuscharmut bestehen oder
darin, dass die Öffnungen besser verschließbar sind, so dass das Entweichen von
ungenutzter Kühlluft in den Betriebsphasen des Radialventilators möglichst vollständig
verhindert wird. Beispielsweise ist ein geeigneter Mechanismus, bestehend
aus Ritzel und Zahnstange in der bereits genannten DE197 24 728 A1 offenbart
worden, der dort eine Schiebejalousie bewegt. Über angetriebene Rollen bewegbare
Abdeckungen oder dergleichen gehen beispielsweise aus DE-OS 25 01 013
hervor. In der DE-OS wird mittels des dortigen Rollenantriebs zwar ein Rollbandfilter
bewegt, jedoch ist der dort gezeigte Rollenantrieb selbst auch im vorliegenden
Zusammenhang geeignet. Der Verweis auf diese Dokumente soll hier eine detailliertere
Darstellung ersetzen. Die Abdeckung kann insgesamt aus flexiblem Material
bestehen oder nur in dem auf - oder abwickelbaren Bereich flexibel sein, wobei
die Abdeckung selbst eine steife Platte sein kann, die mittels des Rollenantriebs in
oberen und unteren Führungen, die an der Frontplatte angeordnet sind, bewegbar
ist, wodurch die Öffnungen geöffnet oder geschlossen werden.However, other locking elements and locking mechanisms can also be used
are used that serve the same purpose. Such closure elements
and mechanisms are the subject of
Die Form, Anzahl und Anordnung der Öffnungen in der Frontwand kann beliebig sein und richtet sich danach, wie groß der zusätzliche Volumenstrom sein soll, wie er sich verteilen soll, welche Verschlußelemente und Verschlußmechanismen ausgewählt werden, selbstverständlich auch nach Aspekten der Festigkeit und Stabilität, wenn die Frontwand als tragendes Element der Kühlanlage dient und nach anderen baulichen oder funktionellen Restriktionen.The shape, number and arrangement of the openings in the front wall can be any and depends on how large the additional volume flow should be, how it should distribute which locking elements and locking mechanisms selected are, of course, also in terms of strength and stability, if the front wall serves as a load-bearing element of the cooling system and after other structural or functional restrictions.
Es ist bei konventionellen Kühlanlagen oder bei im Kühlluftstrom liegende, in einer Öffnung der Motorkapsel eingebaute Ladeluftkühler, z. B. aus der DE 35 45 650 A1, bestens bekannt, durch den Fahrtwind oder durch einen die Temperatur in der Motorkapsel aufnehmenden Thermostaten Klappjalousien oder dergleichen zu öffnen, um den Fahrtwind durch den Ladeluftkühler und in die Motorkapsel strömen zu lassen. Bei diesen Lösungen gibt es jedoch in der Regel keinen Ventilator, so dass die Kühlung nur durch den Staudruck möglich ist. Bei solchen Lösungen sind der oder die Wasserkühler und andere Kühler separat, d. h. an einem anderen Ort im Motorraum des Kraftfahrzeugs angeordnet, die in der Regel zusätzlich einen die Kühlluft fördernden Axialventilator aufweisen müssen, um effizient zu arbeiten. Das ist insgesamt wesentlich aufwendiger - auch unter dem Gesichtspunkt eines sparsamen Energieeinsatzes. Irgendwelche Anregungen, um die Effizienz im Staudruckbetrieb bei Kühlanlagen der vorgeschlagenen Art zu verbessern, ohne die Wirksamkeit der Kühlung im Ventilatorbetrieb zu verschlechtern, gehen aus der genannten Veröffentlichung nicht hervor.It is in a conventional cooling system or in the cooling air flow, in one Opening the engine capsule built-in intercooler, e.g. B. from DE 35 45 650 A1, best known, by the wind or by a temperature in the To open motor capsule-containing thermostats, folding blinds or the like, flow around the airstream through the charge air cooler and into the engine capsule allow. With these solutions, however, there is usually no fan, so that cooling is only possible due to the dynamic pressure. With such solutions are the water cooler (s) and other coolers separately, d. H. at an other place arranged in the engine compartment of the motor vehicle, which is usually an additional Axial fan promoting cooling air must be available in order to work efficiently. The is much more complex overall - also from the point of view of economical Use of energy. Any suggestions for efficiency in back pressure operation to improve cooling systems of the proposed type without the Efficiency of cooling in fan operation deteriorate, go from the not mentioned publication.
Die Erfindung wird nachfolgend in Ausführungsbeispielen beschrieben. Die beiliegenden Figuren zeigen folgendes.The invention is described below in exemplary embodiments. The enclosed Figures show the following.

Fig. 2 vertikaler Schnitt gemäß der Linie II - II in Fig. 1;Fig. 2 vertical section along the line II - II in Fig. 1;
Fig. 3 vertikaler Schnitt entlang der Linie III - III in Fig. 1;Fig. 3 vertical section along the line III - III in Fig. 1;
Die Kühlanlage besteht gemäß Fig. 1 aus rechts und links angeordneten Wasserkühlern
1; 2 und einem oben angeordneten Ladeluftkühler 3 und ist für schwere
Kraftfahrzeuge vorgesehen. Das Kühlnetz 20 des Ladeluftkühlers 3 ist in seiner
Blocktiefe 30 wesentlich größer als die Blocktiefe 30 der Wasserkühler 1; 2. Die
Blockbreite hat das Bezugszeichen 31 und ist beim Ladeluftkühler 3 ebenfalls größer
als bei den Wasserkühlern 1; 2. In diesem Ausführungsbeispiel befindet sich
unten kein Kühler. Die Unterseite ist deshalb durch die Wand 26 (Fig. 3) verschlossen.
Außerdem ist die nicht deutlich gezeigte Rückseite der Kühlanlage
mittels einer Wand verschlossen. In der Frontwand 12 befindet sich eine Ansaugöffnung
11 mit einer Düse 10, die in diesem Ausführungsbeispiel nicht zentral in
der Frontwand 12, sondern geringfügig zum oberen Bereich verschoben, angeordnet
wurde. In der Ansaugöffnung 11 sind die Ausblasschaufeln 7 und die Rückwand
9 des Laufrades des Radialventilators 6 zu erkennen. Die Achse 5 des Radialventilators
6 wurde durch eine gestrichelte Linie kenntlich gemacht. In Richtung
dieser Achse 5 wird die Kühlluft angesaugt, radial umgelenkt und in Richtung auf
die Kühler 1; 2; 3 geblasen. Die Kühler 1; 2; 3 besitzen ein bekanntes Kühlnetz 20,
bestehend aus Flachrohren 22 mit dazwischen angeordneten Wellrippen 23, wobei
das Kühlnetz 20 in Fig. 2 detaillierter gezeigt ist. Die Flachrohre 22 erstrecken sich
jeweils zwischen den je zwei Sammelkästen 21 der einzelnen Kühler 1; 2; 3, so
dass sie quer zur Ventilatorachse 5 verlaufen. Im in der Fig. 1 gezeigten Ausführungsbeispiel
sind insgesamt neun Öffnungen 13 in der Frontwand 12 vorhanden,
wovon zwei Öffnungen 13 oben, jeweils eine auf jeder Seite, und die restlichen
sieben Öffnungen 13 unterhalb der Ansaugöffnung 11 angeordnet wurden. Die
Frontwand 12 ist im Fahrbetrieb des Kraftfahrzeuges dem Fahrtwind ausgesetzt.
Bei den Öffnungen 13 handelt es sich um im wesentlichen rechteckige Durchbrüche,
wobei es auf die Form, die Anzahl und die Anordnung der Öffnungen 13 nicht
besonders ankommt. In einem nicht gezeigten Ausführungsbeispiel sind die abdeckbaren
Öffnungen 13 bzw. wesentliche Teile der Frontwand 12 grillartig, also
beispielsweise nach Art eines Kühlergrills ausgestaltet. Die oberen beiden Öffnungen
13 sind im geöffneten Zustand eingezeichnet worden, d. h. die Abdeckung 15
steht nach innen hin einseitig ab, so dass im Fahrbetrieb des Kraftfahrzeuges von
außen anströmende Kühlluft durch die Öffnungen 13 in das Innere der Kühlanlage
eindringen kann. Die unteren Öffnungen 13 wurden geschlossen gezeichnet, wobei
es sich versteht, dass das nur aus Gründen der Anschaulichkeit so gezeichnet
wurde. Im Staudruckbetrieb sind sämtliche Öffnungen 13 geöffnet und im Betrieb
des Radialventilators 6 sind hingegen sämtliche Öffnungen 13 mittels der Abdekkungen
14 geschlossen. Die Abdeckungen 14 bestehen aus einem geeigneten
Gummi. Sie sind oberhalb der Öffnungen 13 innen an der Frontwand 12 befestigt.
Die Befestigung ist selbstverständlich auch außen an der Frontwand 12 möglich.
Aus funktionellen Gründen muß in diesem Ausführungsbeispiel die Abdeckung 14
selbst allerdings innen an der Frontwand 12 angeordnet sein. Die Befestigung ist
stabil ausgeführt, damit die dauerhafte Funktion der Abdeckungen 14 über den
gesamten Nutzungszeitraum der Kühlanlage gesichert ist. Eine solche Abdeckung
14 ist in der Fig. 2 zu erkennen. Die Fig. 2 zeigt die Abdeckung 14 in einer Stellung,
wie sie im Staudruckbetrieb der Kühlanlage, jedoch an sämtlichen Öffnungen
13, vorhanden ist. Genauso wie die Form, Anzahl und Anordnung der Öffnungen
13 verschieden ausgestaltet sein können, können auch die Abdeckungen 14 verschieden
konstruiert sein. Es muß nicht zwangsläufig jeder einzelnen Öffnung 13
eine einzelne Abdeckung 14 zugeordnet sein. Mehrere vorzugsweise kleinere Öffnungen
13 können mittels einer einzigen Abdeckung 14 verschließbar sein.According to FIG. 1, the cooling system consists of
Die Fig. 2 zeigt ferner deutlicher als die Fig. 1, dass der Ladeluftkühler 3 neben der
größeren Blocktiefe 30 auch noch eine größere Blockbreite 31 aufweist, so dass
ein deutlicher Überstand 32 des Ladeluftkühlers 3 nach vorne über die Frontwand
12 vorhanden ist. Mit solchen Maßnahmen kann den Kühlanforderungen an jeden
einzelnen Kühler in einem konkreten Anwendungsfall bestens entsprochen werden.
Der Überstand 32 wird mittels eines Abdeckbleches 25 ausgeglichen.FIG. 2 also shows more clearly than FIG. 1 that the
Im vertikalen Schnitt in Fig. 2 ist das oben bereits beschriebene Kühlnetz 20 des
einen Wasserkühlers 1 deutlich zu erkennen.In the vertical section in FIG. 2, the
In Fig. 3 ist gezeigt, dass jede Öffnung 13 eine extra Abdeckung 14 besitzt, was
bei der gewählten Größe der Öffnungen 13 vorteilhaft ist, weil eine bessere Abdichtung
beim Betrieb des Radialventilators 6 erwartet wird. Ferner muß die Größe
der Abdeckungen 14 einerseits natürlich so gewählt werden, dass sie nicht in das
Radiallaufrad gelangen oder beschädigt werden können und andererseits, dass sie
die Öffnungen 13 ausreichend dicht geschlossen halten können.In Fig. 3 it is shown that each
