Description

Einrichtung zur Veräampfungskühlung für Brennkratmaschinen zum Antrieb von Rammen Rammen, welche als Verpuffungskraftmaschinen betrieben werden, lassen sich nicht wie andere VerpuffungsIraftmaschinen durch fließendes oder rückgekühltes Wasser kühlen, denn den Erschütterungen, denen die Ramme ausgesetzt ist, würden die erforderlichen Zuleitungen und Ableitungen nicht standhalten. Man war deshalb hier in der Hauptsache auf die Luftkühlung angewiesen. Der wirksameren Kühlung durch zur Verdampfung gebrachtes Kühlwasser stand die besondere Schwierigkeit im Wege, den entstehenden Dampf abzuleiten, ohne daß Kühlwasser mitgerissen wird, weil das Wasser beim Hochfliegen und Aufschlagen der Ramme im ganzen Kühlwasserraum sehr stark herumgeschleudert wird und dabei auch zu den Dampfauslässen gelangt.Device for evaporation cooling for internal combustion machines to drive by ramming rams, which are operated as deflagration engines not like other deflagration engines through flowing or recooled Cool the water because the vibrations to which the ram is exposed would cannot withstand the necessary feed lines and discharges. One was therefore here mainly dependent on air cooling. The more effective cooling through evaporated cooling water stood in the way of the particular difficulty to dissipate the resulting steam without cooling water being entrained, because that Water when soaring and hitting the ram in the entire cooling water space a lot is thrown around strongly and also reaches the steam outlets.

Gemäß der Erfindung ist es jedoch gelungen, diese sehr wirksame und keinerlei Zu- oder Ableitungen für Kühlwasser benötigende Kühlung für Zylinder von Rammen verwendbar zu machen.According to the invention, however, it has been possible to make this very effective and no inlets or outlets for cooling water for cylinders of To make ramming usable.

Im wesentlichen besteht die Erfindung darin, daß der Kühlmantel m einen unteren, mit Wasser zu füllenden Raum und einen oberen Dampfraum durch eine Abschnürung solcher Art unterteilt wird, daß in den oberen Raum nur Spritzwasser und Dampf gelangen und infolgedessen der Dampf aus ihm ohne Verlust an unverdampftem Wasser ausgelassen werden kann.Essentially, the invention consists in that the cooling jacket m a lower space to be filled with water and an upper steam space through a Constriction is divided in such a way that only splash water in the upper space and steam pass, and consequently the steam out of it, without loss of the unevaporated Water can be omitted.

Zwei Ausführungsbeispiele sind in der Zeichnung je im Mittellängsschnitt dargestellt.Two exemplary embodiments are each shown in the drawing in central longitudinal section.

Gemäß Fig. z ist der Arbeitszylinder a der Ramme von einem Blechmantel b umgeben, derart, daß zwischen diesem Blechmantel und dem Zylinder ein. Kühlmantel e verbleibt, der in der Hauptsache mit Wasser'd gefüllt wird. Der Zylinderdeckel e ist mit einem als Kühlmantel dienenden Hohlraum fversehen. Der Raume steht mit dem Raum/ durch verhältnismäßig ;enge Kanäleg in Verbindung. Das Wasser d im Raum c kühlt den äußeren Umfang des Zylinders unmittelbar. Der sich entwickelnde Dampf gelangt durch die Kanäle g in den Hohlraum Fund kann von dort durch Auslässe lt, die mit geeignet angebrachten Prallflächen i versehen sind, ins Freie abziehen. Bei den Erschütterungen, die mit dem Betrieb der Ramme verknüpft sind, bewegt sich zwar auch das Wasser d in dem Raum c auf und ,ab. Es kann jedoch die Auslässe lt nicht unmittelbar erreichen, sondern durch die Kanäle & kann nur Spritzwasser in den Raum/ gelangen, welches dann zur Kühlung des Bodens k des Zylinderdeckels e sowie des Ventils m dient.According to Fig. Z, the working cylinder a of the ram is surrounded by a sheet metal jacket b, such that between this sheet metal jacket and the cylinder. Cooling jacket e remains, which is mainly filled with water'd. The cylinder cover e is provided with a cavity f serving as a cooling jacket. The room is connected to the room / through relatively narrow canals. The water d in space c cools the outer circumference of the cylinder immediately. The steam that develops passes through the channels g into the cavity F and can be drawn off into the open from there through outlets lt, which are provided with suitably attached baffles i. In the case of the vibrations associated with the operation of the ram, the water d also moves up and down in the room c. However, it cannot reach the outlets lt directly, but only spray water can get into the room / through the channels &, which then serves to cool the bottom k of the cylinder cover e and the valve m.

Bei der Ausführungsform gemäß Fig. 2 besteht die äußere Wand bi des Kühlmantels c mit dem Arheitszylinder aus einem Stück. Der als Wasserbehälter dienende Raum c steht mit dem Dampfraum f nur durch einen ringförmigen Verbindungskanal o oder eine entsprechende Einschnürung in Verbindung, die zweckmäßig so gestaltet ist, daß das sich im Raum c nach oben bewegende Wasser nach dem Zylinderboden h1 hin abgelenkt wird.In the embodiment according to FIG. 2, the outer wall bi of the cooling jacket c consists of one piece with the arm cylinder. The space c serving as a water container communicates with the steam space f only through an annular connecting channel o or a corresponding constriction, which is expediently designed so that the water moving upwards in space c is deflected towards the cylinder base h1.

Auf diese Weise kann eine besonders wirksame Ver dampfungskühlung des Zylinderbodens hl erreicht werden, wiederum, ohne daß die Gefahr besteht, daß unverdampftes Wasser durch die Auslässe lt verlorengehen kann.In this way, a particularly effective evaporative cooling can be achieved of the cylinder bottom hl can be achieved, in turn, without the risk that Unevaporated water can be lost through the outlets.
