Description
Kühleinrichtung von Zylinderdeckeln für Verbrennungskraftmaschinen. Die Kühlung von Zylinderdeckeln ist bekanntlich um so wirksamer, je höher die Geschwindigkeit ist, mit welcher der Kühlstrom die einer starken Wärmezufuhr ausgesetzten Teile des Deckels bestreicht. Dies wird meistens durch möglichst kleine Bemessung der Durchflußquerschnitte im.. Wasserraum . deäs Deckels erreicht, wodurch der Wasserraum im allgemeinen verhältnismäßig klein ausfällt. Es ist nun bei Maschinen mit angekuppelten Kühlpumpen die Möglichkeit vorhanden, daß bei etwaigem Aussetzen der Kühlung (z. B. beim Stillsetzei der Maschine) das in den Zylinderdeckeln befindliche Wasser infolge der den Deckelwandungen noch aus dem Verbrennungsraum zuströmenden Wärme sich stark erhitzt, unter Umständen sogar verdampft, wodurch eine unzulässige Temperatursteigerung eintritt. Diese Gefahr soll durch die Erfindung beseitigt werden. Cooling device for cylinder covers for internal combustion engines. It is known that the cooling of cylinder covers is the more effective, the higher the speed with which the cooling flow sweeps the parts of the cover exposed to a strong supply of heat. This is usually achieved by dimensioning the flow cross-sections in the .. water area as small as possible. deäs lid reached, whereby the water space is generally relatively small. In machines with coupled cooling pumps, there is the possibility that, if the cooling is interrupted (e.g. when the machine is shut down), the water in the cylinder lids will heat up considerably as a result of the heat still flowing into the lid walls from the combustion chamber even evaporates, whereby an impermissible increase in temperature occurs. This risk is intended to be eliminated by the invention.
Zu diesem Zweck wird abfließendes Kühlwasser in einen besonderen Raum geleitet, bis dieser ganz mit Wasser gefüllt ist. Sobald nun aus obigen Gründen das Wasser im Kühlraum stark erhitzt oder verdampft ist, fließt ein Teil des Inhalts des abgetrennten Raumes infolge seines größeren spezifischen Gewichtes in den Kühlraum zurück und schützt den Deckel vor überrzäSiger Erwärmung. - Die Zeichnung veranschaulicht -ein Ausführungsbeispiel des Erfindungsgegenstandes, .und: zwar zeigt: Abb. i einen Längsschritt des Deckels und Abb.2 einen Querschnitt des Deckels durch den Kühlraum. Das Kühlwasser tritt bei a in, den Deckel ein, bestreicht im Raum b die stark @ erhitzten Teile und tritt bei c aus dem Deckel aus. Von dem Abflußrohr d für das Kühlwasser führt bei e eine Abzweigung nach dem Behälter f: Sobald das Wasser im Kühlraum eine höhere Temperatur als das im Behälter aufgespeicherte Wasser hat, sobald ferner bei gesteigerter Wärmezufuhr das Wasser im Kühlraum verdampft, tritt selbsttätig das aufgespeicherte Wasser durch die Rohrleitung g und Rückschlagventil h in den Kühlraum ein. Hierdurch wird die bei kleinem Kühlraum vorhandene Gefahr des Ausglühens des Deckels beseitigt.For this purpose, draining cooling water is led into a special room until it is completely filled with water. As soon as the water in the cold room is strongly heated or evaporated due to the above reasons, part of the contents of the separated room flows back into the cold room due to its greater specific weight and protects the lid from excessive heating. The drawing illustrates an exemplary embodiment of the subject matter of the invention, and indeed shows: Fig. 1 shows a longitudinal step of the cover and Fig. 2 shows a cross section of the cover through the cooling space. The cooling water enters at a in the lid, a, b space sweeps in the highly heated portions @ and emerges from the lid at c. From the drain pipe d for the cooling water there is a branch at e to the container f: As soon as the water in the cold room has a higher temperature than the water stored in the container, as soon as the water in the cold room evaporates with increased heat supply, the stored water automatically passes through the pipeline g and check valve h into the cold room. This eliminates the risk of the lid burning out if the cooling space is small.
Ein weiteres Ausführungsbeispiel zeigt Abb.3, welche einen Deckel im Querschnitt darstellt. Hier ist .statt des Behälters der außerhalb des Kühlraumes liegende Teil l des Zylinderdeckels m zur Aufnahme von Kühlwasser ausgebildet. Das Wasser tritt bei n in den Deckel ein, durchfließt den Kühlraum p und- verläßt den Deckel bei q. Das aufgespeicherte Wasser kann hier durch Rückschlag.-ventil r in den Kühlraum eintreten. Sinngemäß kann die Erfindung auch für Verbrennungskraftmaschinenzylinder Anwendung finden.Another embodiment is shown in Fig.3, which has a lid represents in cross section. Instead of the container, this is the one outside the refrigerator lying part l of the cylinder cover m designed to accommodate cooling water. That Water enters the lid at n, flows through the cooling space p and leaves the Cover at q. The stored water can here through the non-return valve r in enter the refrigerator. Accordingly, the invention can also be used for internal combustion engine cylinders Find application.
