Die Erfindung betrifft einen Verbrennungsmotor mit einem Zylinderblock, einem Zylinderkopf und einem Steuergehäusedeckel, wobei der Steuergehäusedeckel und der Zylinderblock ein Steuergehäuse sowie eine Pumpeneinlasskammer und eine Pumpenauslasskammer bilden, welche voneinander getrennt sind.The invention relates to an internal combustion engine with a Cylinder block, a cylinder head and a timing case cover, the timing case cover and the cylinder block Control housing as well as a pump inlet chamber and a Form the pump outlet chamber, which are separated from each other.

Die US-A-4,938,185 zeigt einen Steuergehäusedeckel für einen Verbrennungsmotor, wobei in dem Steuergehäusedeckel Pumpenkammern sowie Anschlüsse eines Kühlmittelsystems vorgesehen sind, in dem diese in den Steuergehäusedeckel eingeformt sind und wobei dieser im wesentlichen einstückig ausgebildet ist.US-A-4,938,185 shows a timing case cover for one Internal combustion engine, with pump chambers in the timing case cover and connections of a coolant system are provided are in which they are molded into the timing case cover and which is formed essentially in one piece.

Das der Erfindung zugrunde liegende Problem wird darin gesehen, dass im Fall von Undichtigkeiten in dem Steuergehäusedeckel Kühlmittel in das Steuergehäuse eindringen kann und dort vorhandenes Schmiermittel verunreinigen bzw. die Funktion von dort angeordneten Bauteilen beeinträchtigen kann.The problem underlying the invention is seen in that in the event of leaks in the timing case cover Coolant can penetrate into the control housing and there contaminate existing lubricant or the function of components arranged there can impair.

Dieses Problem wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst, wobei in den weiteren Patentansprüchen die Lösung in vorteilhafter Weise weiterentwickelnde Merkmale aufgeführt sind.This problem is solved according to the invention by the teaching of the patent claim 1 solved, the in the further claims Features that further develop features in an advantageous manner are listed.

Der Steuergehäusedeckel der vorliegenden Erfindung stellt eine Abdeckung für eine Ventilsteuerung zur Verfügung. Die Ventilsteuerung ist in einem Steuergehäuse angeordnet, welches durch die Frontfläche des Zylinderblocks und den Steuergehäusedeckel gebildet wird. Der Steuergehäusedeckel kann darüber hinaus mit eingeformten Anschlüssen versehen sein, um den Steuergehäusedeckel mit einem Kühler bzw. einem Wärmetauscher zu verbinden, um Kühlmittel zu dem Wärmetauscher als auch von diesem wegzuleiten. Der Steuergehäusedeckel bildet eine Pumpeneinlasskammer, welche mit dem Kühlmitteleinlass verbunden sein kann, um Kühlmittel von dem Wärmetauscher zu erhalten, sowie eine Kühlmittelauslasskammer, welcher Kühlmittel von einer Kühlmittelpumpe zugeführt werden kann. Die Pumpenauslasskammer kann mit einem Kühlmitteleinlass in dem Zylinderblock in Verbindung stehen, um Kühlmittel zu dem Zylinderblock zu leiten. Das Kühlmittel fließt in bekannter Art und Weise durch den Zylinderblock und zu einem Zylinderkopf und wird von dem Zylinderkopf in eine Kammer zur Aufnahme von heißem Kühlmittel abgegeben, welche ebenfalls in den Steuergehäusedeckel eingeformt sein kann. Eine solche Kammer steht mit einem Kühlmittelauslass in dem Steuergehäusedeckel in Verbindung, um das Kühlmittel an den Wärmetauscher abzugeben. Dieser Kühlmittelauslass kann einen Thermostaten beherbergen.The timing case cover of the present invention provides one Cover for a valve control available. The Valve control is arranged in a control housing, which through the front surface of the cylinder block and the Control housing cover is formed. The timing case cover can also be provided with molded connections in order the timing case cover with a radiator or a Connect heat exchanger to coolant to the heat exchanger as well as leading away from this. The timing case cover forms a pump inlet chamber which communicates with the coolant inlet may be connected to coolant from the heat exchanger received, as well as a coolant outlet chamber, which Coolant can be supplied from a coolant pump. The Pump outlet chamber can have a coolant inlet in the Connect cylinder block to coolant to the To direct cylinder block. The coolant flows in a known manner and way through the cylinder block and to a cylinder head and is from the cylinder head into a chamber for receiving hot coolant, which is also in the Control housing cover can be molded. Such a chamber stands with a coolant outlet in the timing case cover in Connection to deliver the coolant to the heat exchanger. This coolant outlet can house a thermostat.

Der Steuergehäusedeckel kann mit dem Zylinderblock verschraubt werden und muss nicht mit dem Zylinderkopf verschraubt sein. Entsprechend ist es möglich, eine flexible Dichtung zwischen dem Zylinderkopf und dem Steuergehäusedeckel vorzusehen, um eine dichte Verbindung sicherzustellen.The timing case cover can be screwed to the cylinder block and does not have to be screwed to the cylinder head. Accordingly, it is possible to have a flexible seal between the cylinder head and the timing case cover to provide ensure a tight connection.

An einer Frontseite des Steuergehäusedeckels kann eine Kühlmittelpumpe angebracht sein, welche Kühlmittel durch eine Öffnung in dem Steuergehäusedeckel zu der Pumpeneinlasskammer erhält. Ein Auslass dieser Kühlmittelpumpe ist durch eine weitere Öffnung in dem Steuergehäusedeckel zu einer Pumpenauslasskammer gerichtet, um dem Zylinderblock Kühlmittel zuzuführen.One can be located on a front of the timing case cover Coolant pump attached, which coolant through a Opening in the control housing cover to the pump inlet chamber receives. An outlet of this coolant pump is through a another opening in the timing case cover to one Pump outlet chamber directed to the cylinder block coolant supply.

Der Steuergehäusedeckel kann darüber hinaus einen Umgehungskanal von der Kammer zur Aufnahme heißen Kühlmittels zu der Pumpeneinlasskammer aufweisen, um einen Kühlmittelfluss durch den Verbrennungsmotor zu ermöglichen, bevor der Thermostat öffnet.The control housing cover can also one Bypass channel from the chamber to receive hot coolant to the pump inlet chamber to maintain a coolant flow through the internal combustion engine before the Thermostat opens.

Ein neuer Aspekt des beschriebenen Steuergehäusedeckels besteht in der Anordnung der Pumpeneinlasskammer zwischen der Pumpenauslasskammer und dem Steuergehäuse. Als Ergebnis wird Kühlmittel, welches von der auf der Druckseite der Kühlmittelpumpe liegenden Pumpenauslasskammer entweicht, in die Pumpeneinlasskammer und nicht in das Steuergehäuse fließen, wo es das Schmiermittel des Verbrennungsmotors verunreinigen würde. Eine solche Anordnung der Kammern in dem Steuergehäusedeckel verbessert die Zuverlässigkeit des Verbrennungsmotors, indem es den Eintritt von Kühlmittel in das Schmiermittel bzw. -öl verringert oder ausschließt.There is a new aspect of the described control housing cover in the arrangement of the pump inlet chamber between the Pump outlet chamber and the control housing. As a result Coolant, which is from the on the pressure side of the Coolant pump lying pump outlet chamber escapes into the Pump inlet chamber and do not flow into the timing case where contaminate the lubricant of the internal combustion engine would. Such an arrangement of the chambers in the Timing cover improves the reliability of the Internal combustion engine by preventing the entry of coolant into the Lubricant or oil reduced or excluded.

Der Steuergehäusedeckel 20 ist derart ausgebildet, dass die Niederdruck-Pumpeneinlasskammer 58 die Hochdruck-Pumpeneinlasskammer 64 vollständig von dem Steuergehäuse 74 trennt. Folglich wird jegliches Kühlmittel, dass aus der Pumpenauslasskammer 64 entweicht, in die Pumpeneinlasskammer 58 gelangen, anstatt in das Steuergehäuse 74 zu fließen, wo das Kühlmittel das Schmieröl verunreinigen würde. Die Anordnung der Kühlmittelkammern 58, 64 innerhalb des Steuergehäuses 74 verbessert die Zuverlässigkeit der Brennkraftmaschine 10 indem die Möglichkeit eines Entweichens von Kühlmittel in das Schmieröl reduziert oder ausgeschlossen wird.The control housing cover 20 has a control housing 74, which essentially consists of the projecting side walls 38 and the protruding partition 40 is determined. The Control housing 74 communicates with the lubricating oil Internal combustion engine, which is used to a Lubricate valve timing and a valve timing chain. The Control housing cover 20 is designed such that the Low pressure pump inlet chamber 58 the high pressure pump inlet chamber 64 completely from the control housing 74 separates. Consequently, any coolant that comes from the Pump outlet chamber 64 escapes into pump inlet chamber 58 get instead of flowing into the control housing 74, where that Coolant would contaminate the lubricating oil. The arrangement of the Coolant chambers 58, 64 within the control housing 74 improves the reliability of the engine 10 by the possibility of coolant escaping into the Lubricating oil is reduced or excluded.

Das Pumpengehäuse 30 weist einen Abflussanschluss 76 auf, um es zu ermöglichen, dass Kühlmittel aus dem Zylinderblock 14 und Zylinderkopf 18 abzulassen. Durch das Anordnen des Abflussanschlusses 76 in dem Pumpengehäuse 30 werden an dem Zylinderblock 12 weniger Bearbeitungsvorgänge erfordert. Der Abflussanschluss kann zu dem kleineren Pumpengehäuse 30 mit geringeren Kosten hinzugefügt werden.The pump housing 30 has a drain port 76 to it to allow coolant from the cylinder block 14 and Lower the cylinder head 18. By arranging the Drain connection 76 in the pump housing 30 are on the Cylinder block 12 requires fewer machining operations. The Drain connection to the smaller pump housing 30 with lower costs can be added.

Die Kühlmittelpumpe 22 wird in Fig. 3 detaillierter dargestellt. Die Kühlmittelpumpe 22 weist ein Laufrad 78 mit einer Mehrzahl von Flügeln 80 auf. Das Laufrad 78 dreht im Uhrzeigersinn, wie es in Fig. 3 gezeigt wird, um das Kühlmittel aus dem Laufrad 78 und durch eine Kammer 82 in dem Pumpengehäuse 30 zu bewegen. Das Kühlmittel fließt dann durch die Öffnung 68 in dem Steuergehäusedeckel 20 in die Pumpenauslasskammer 64.The coolant pump 22 is shown in more detail in FIG. 3 shown. The coolant pump 22 has an impeller 78 a plurality of wings 80. The impeller 78 rotates in Clockwise, as shown in Fig. 3, around the coolant from the impeller 78 and through a chamber 82 in the Pump housing 30 to move. The coolant then flows through the opening 68 in the timing case cover 20 in the Pump outlet chamber 64.

Der Steuergehäusedeckel 20 stellt eine integrale, einstückige Anordnung zur Verfügung, die sowohl den Einlass- als auch den Auslassanschluss bildet, um Kühlmittel zu und weg von der Brennkraftmaschine 10 fließen zu lassen. Zusätzlich ist der Kühlmittelpfad durch den Steuergehäusedeckel 20 zur Erzielung einer hohen Zuverlässigkeit ausgebildet, indem die Pumpenauslasskammer 64 von dem Steuergehäuse 74 isoliert wird.The control housing cover 20 provides an integral, one-piece Arrangement available that covers both the inlet and the Exhaust port forms to coolant to and away from the To let internal combustion engine 10 flow. In addition, the Coolant path through the control housing cover 20 to achieve of high reliability by the Pump outlet chamber 64 is isolated from the control housing 74.
