Description
Gegenstand der Erfindung ist eine Verbesserung der Motorenivauben für luftgekühlte Motoren mit Führung der Kühlluft.The subject of the invention is an improvement the motor cover for air-cooled motors with guidance of the cooling air.
Die vorliegende Erfindung hat eine Reihe von Maßnahmen zum Gegenstand, um die Luft durch eine bestimmte Art von Öffnungen in die Haube einzulassen. Vorzugsweise werden zwei Arten von Öffnungen verwendet, von denen die eine fast unmittelbar vor den Zylindern liegt, wähnend die andere in deren Zwischenräumen vorgesehen ist, wobei zweckmäßigerweise die Größe der Öffnungen beider Gruppen regelbar ist.The present invention has a number of measures to the subject To let air into the hood through a certain type of vents. Preferably be two types of openings are used, one of which is almost immediately in front of the cylinders lies, while the other is provided in the spaces between them, expediently the size of the openings in both groups can be regulated.
Die Erfindung bezweckt, durch. Einleitung und Verteilung der Kühlluft im Innern der Haube die Zylinderwände in'allen ihren Teilen ungefähr auf der gleichen Temperatur zu halten, trotz Veränderungen im Laufe der Maschine und trotz Schwankungen der Außentemperatur. The invention aims by. Introduction and distribution of the cooling air inside the Cover the cylinder walls in all their parts Maintain roughly the same temperature, despite changes over the course of the year Machine and despite fluctuations in the outside temperature.
Die Zeichnungen zeigen beispielsweise eine Ausführungsform der Erfindung bei einem Sternmotor, wie er zur Verwendung bei Flugzeugen geeignet ist.The drawings show, for example, an embodiment of the invention in a Radial engine such as is suitable for use in aircraft.
Fig. ι stellt den Grundriß der Fig. 2 mit teilweisem axialem Schnitt nach Linie 1-1 dar.Fig. Ι represents the plan of FIG. 2 with a partial axial section along line 1-1 represent.
Fig. 2 ist eine Aufsicht der Motorhaube, an der teilweise Bauteile fortgelassen sind.Fig. 2 is a top plan view of the engine hood, with components partially removed.
Fig. 3 ist ein Schnitt nach der Linie 3-3 der Fig. 2.FIG. 3 is a section along line 3-3 of FIG.
Die Kühlluft wird an der Vorderwand der Haube durch die Öffnungen c° oder c10 eingelassen, die ganz oder teilweise durch, einen Schieber verschlossen werden können, der beispielsweise aus dem Ring d besteht, der um die Motorenachse drehbar und seinerseits mit Öffnungen d° versehten ist. Von den zwei gemäß der- Erfindung vorgesehenen Gruppen von EintrittsöfEnungen c° und c10 liegen die einen, mit cw bezeichneten, vor den Zylindern, und zwar in Richtung von deren Längsachse oder leicht gegen diese versetzt, um dem Umstand Rechnung zu tragen, daß infolge der Pr opeller drehung die Luft schräg eintritt, so daß diese Öffnungen einen Teil der Kühlluft unmittelbar auf die vorderen Zylinderwände richten. Die Eintrittsöffnungen c° der anderen Gruppe sind zweckmäßig etwas weiter als die ersterwähnten und zwischen ihnen in beispielsweise einer axialen Ebene angeordnet, die durch die Winkelhalbierungen der verschiedenen Zylinderachsen gebildet werden.The cooling air is admitted on the front wall of the hood through the openings c ° or c 10 , which can be completely or partially closed by a slide, which consists, for example, of the ring d , which rotates around the motor axis and is in turn provided with openings d ° is. Of the two groups of inlet openings c ° and c 10 provided according to the invention, the one designated c w are located in front of the cylinders, namely in the direction of their longitudinal axis or slightly offset from this, in order to take account of the fact that As a result of the Pr opeller rotation, the air enters at an angle, so that these openings direct part of the cooling air directly onto the front cylinder walls. The inlet openings c ° of the other group are expediently somewhat wider than the first mentioned and are arranged between them in an axial plane, for example, which are formed by the bisection of the various cylinder axes.
Diese Unterteilung der Eintrittsöffnungen, denen man vorzugsweise eine trapezförmige , oder dreieckige Form gibt, hat eine zweckmäßige Regelung der Kühlung der Zylinder-"wände zur Folge und verhindert, daß die vorn Hegenden Wandteile unzulässig stark gekühlt werden, wie es bei Verwendung der Öffnungen c° allein unter Umständen gelegent-This subdivision of the inlet openings, which are preferably a trapezoidal, or triangular shape, has an appropriate control of the cooling of the cylinder "walls as a result and prevents the front wall parts from being cooled excessively, as is the case when using the Openings c ° only occasionally under certain circumstances
lieh der Fall sein könnte. Das Verhältnis der durch die Öffnungen e° und c10· hindurchgehenden Luftmenge kann geändert werden. Diesem Zweck dient der Schieber d, welcher beispielsweise mittels eines zweikabligen Biowdenzugies iß' in beiden Richtungen verschiebbar ist und mit trapezförmigen Öffnungen A B C D derart viersehen ist, daß bei Drehung in der einen öder anderen Richtung die leinen oder anderen Öffnunjgen c° oder c10 geöffbet oder geschlossen werden.lent could be the case. The ratio of the amount of air passing through the openings e ° and c 10 · can be changed. This is the purpose of the slide d, which can be moved in both directions by means of a two-wire Biowdenzugies iß 'and is four-sided with trapezoidal openings ABCD in such a way that when turned in one or the other direction, the lines or other openings c ° or c 10 open or getting closed.
Statt dessen kann auch jede andere Art der Regelung erfolgen, beispielsweise für beide Arten der Öffnungen" je ein besonderer Sperrschieber vorgesehen werden.Instead, any other type of regulation can also take place, for example for both types of openings "each have a special locking slide.
