Description

Die Erfindung bezieht sich auf luftgekühlte Brennkraftmaschinen in Reihenbauart der Zylinder mit hängenden Ventilen, welche so angeordnet sind, da,ß die durch das Ein- und Auslaßventil eines Zylinders gegebene Ebene einen spitzen Winkel zur Längsachse der Maschine: einschließt und die Kühlluft in dem diesem Winkel ungefähr entsprechenden Nebenwinkel geführt ist.The invention relates to air-cooled internal combustion engines in In-line design of the cylinders with overhead valves, which are arranged in such a way that da, ß the plane given by the inlet and outlet valve of a cylinder is pointed Angle to the longitudinal axis of the machine: includes and the cooling air at this angle is guided approximately corresponding secondary angle.

Gemäß der Erfindung wird die zur Kühleng der Zylinder dienende Kühlluft eines jeden Zylinders in mehrere Zonen unterteilt und derart geführt, daß bei dicht aneinandergereihten Zylindern die im Bereich eines Ventilgehäuses sich befindenden Zonen an, von der Kühlluft frei durchströmte Zonen des vor-oder nachgeordneten Zylinders anschließen.According to the invention, the cooling air used for cooling the cylinders is used of each cylinder divided into several zones and guided in such a way that when tight Lined up cylinders that are located in the area of a valve housing Zones of the upstream or downstream cylinder through which the cooling air flows freely connect.

L m die Strömung in Zonen zu gewährleisten, ist es vorteilhaft, Grenzrippen zu bilden, die die benachbarten Rippen in ihrer Höhe überragen. Dabei ist eine Zonenbildung möglich, bei der die oben gelegenen Teile des Zylinderkopfes von einem Frischluftstrom gekühlt «-erden. Auch ist das Ansetzen von Leitblechen vorteilhaft, mit welchen die Zonenströme an den Gehäusen erfaßt oder zur Abströmung gebracht werden. Die Kühlung der übrigen Teile der Zylinder kann auf eine der bereits bekannten Arten erfolgen. Weitere vorteilhafte Einzelheiten sind im folgenden beschrieben.L m to ensure the flow in zones, it is advantageous to border ribs to form, which protrude beyond the neighboring ribs in height. There is a zone formation possible with the parts of the cylinder head located above from a stream of fresh air cooled «-ground. The attachment of guide plates is also advantageous, with which the zone currents on the housings are detected or caused to flow away. the Cooling of the remaining parts of the cylinder can be done in one of the already known ways take place. Further advantageous details are described below.

In der Zeichnung ist der Gegenstand der Erfindung an einem Ausführungsbeispiel %rereinfacht dargestellt, und zwar zeigt Fig. i eine in Achsrichtung der Zylinder gesehene. Zylinderreihe einer luftgekühlten Maschine mit Zy l,inderkopfausbildung und Kühlung gemäß der Erfindung und Fig. 2 einen Schnitt durch einen Zylinderkopf längs der Linie a-a.In the drawing, the subject matter of the invention is based on an exemplary embodiment % shown in simplified form, namely Fig. i shows one in the axial direction of the cylinder seen. Row of cylinders of an air-cooled machine with cylinder head formation and cooling according to the invention and FIG. 2 shows a section through a cylinder head along the line a-a.

Die Zylinderköpfe i der dargestellten Zylinderreihe besitzen zwei Ventilgehäuse ?- und 3 für das Ein- und; Auslaßventil. Die durch die Linie a--a veranschaulichte, durch die Ventilschäfte gelegte Ebene4 schließt mit der Längsachse 5 der Maschine einen Winkel von etwa 45° ein.The cylinder heads i of the cylinder row shown have two valve housings ? - and 3 for the one and; Outlet valve. The plane 4, illustrated by the line a - a and laid through the valve stems, forms an angle of approximately 45 ° with the longitudinal axis 5 of the machine.

Die Zylinderköpfe i sind in üblicher Weise mit Rippen 6 und 7 versehen, die teils senkrecht zur Achsrichtung der Zylinder und teils senkrecht zu den durch diese Rippen 6 gegebenen Ebenen auf den Zylinderköpfen i angeordnet sind. Zum Erhöhen der übersichtlichkeit der Zeichnung sind an zwei Köpfen i lediglich die Rippen dargestellt, die, wie weiter unten beschrieben, gleichzeitig als Trennwände für die Hauptkühlzo:nen dienen. Die auf jeden Zylinderkopf i zuströmende Luft teilt sich in zwei Hauptströme 8 und g. Um die drei sich ergebenden Hauptzonen dieser Ströme 8 und 9, von denen sich der Strom 8 wieder in zwei teils durch die Gehäuse 2 und 3, teiils durch die Rippen io getrennte Teilströme spaltet, an den Zylinderköpfen i kenntlich zu machen, sind auf den Köpfen i zwei Rippen; als Trennwände ii und an den Seiten der Köpfe i und der Ventilgehäuse 2 und 3 Leitbleche 12 dargestellt. Das zwischen je zwei Reihen angebrachte Leitblech 13 dient sowohl zur Führung der zu- wie auch abströmenden Luft. Unter der Annahme, daß sich die Zylinderreihe in der Fahrt- oder Flugrichtung 14 bewegt, ergibt sich dann ein ungefähr durch die Richtungspfeile angedeuteter Verlauf des Kühlluftstromes.The cylinder heads i are provided in the usual way with ribs 6 and 7, which are partly perpendicular to the axial direction of the cylinder and partly perpendicular to the through these ribs 6 given levels are arranged on the cylinder heads i. To increase For the sake of clarity of the drawing, only the ribs are shown on two heads i, which, as described below, also act as partitions for the main cooling zones to serve. The air flowing to each cylinder head i divides into two main flows 8 and g. Around the three main resulting zones of these streams 8 and 9, of which the stream 8 again in two partly through the housing 2 and 3, partly through the Ribs io separate partial flows, to be identified on the cylinder heads i, there are two ribs on the heads; as partitions ii and on the sides of the heads i and the valve housing 2 and 3 baffles 12 are shown. That between every two Rows attached baffle plate 13 serves both to guide the inflowing as well as outflowing Air. Assuming that the cylinder bank is in the direction of travel or flight 14 moves, then results approximately indicated by the directional arrows Course of the cooling air flow.
