Abstract
Description
Die Erfindung betrifft einen Zylinderkopf für eine Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a cylinder head for an internal combustion engine with the features of the preamble of claim 1.
Sie
geht von der deutschen Offenlegungsschrift
Auch wenn der vorliegende Stand der Technik keinen prinzipiellen Nachteil aufweist, soll eine Maßnahme aufgezeigt werden, mit der die Funktionalität der Hülse vergrößert wird.Also if the present state of the art no fundamental disadvantage a measure should be identified with which increases the functionality of the sleeve becomes.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the feature in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung übernimmt die Hülse gleichzeitig die Funktion der Abstützung und Anlagefläche für die Zylinderkopfhaube.By the embodiment of the invention takes over the sleeve at the same time the function of the support and contact surface for the cylinder head cover.
Durch diese funktionale Integration der Abstützung der Zylinderkopfhaube in die Hülse können in vorteilhafter Weise weitere Abstützungen und Anlageflä chen für eine Zylinderkopfhaube am Zylinderkopf entfallen, wodurch die Herstellkosten gesenkt werden.By this functional integration of the support of the cylinder head cover in the sleeve can more advantageously Supports and contact surfaces for one Cylinder head cover omitted on the cylinder head, causing the manufacturing costs be lowered.
Mit der Ausgestaltung gemäß Patentanspruch 2 werden die Ventiltriebsräume gegenüber den Brennräumen schmiermitteldicht abgedichtet. Darüber hinaus weisen derartige Dichtelemente auch schwingungsdämpfende Eigenschaften auf, so dass die ungewünschte Geräuschabstrahlung minimiert ist. Die Abdichtung erfolgt in bevorzugter Weise axial und/oder radial.With The embodiment according to claim 2 the Ventiltriebsräume opposite the combustion chambers sealed lubricant seal. In addition, such Sealing elements also vibration damping properties, so that the unwanted noise emission is minimized. The seal is preferably axially and / or radially.
Die Ausgestaltung gemäß Patentanspruch 3 ist ein besonders bevorzugtes Ausführungsbeispiel.The Embodiment according to claim 3 is a special preferred embodiment.
Mit der Ausgestaltung gemäß Patentanspruch 4 werden ebenfalls die Ventiltriebsräume gegenüber der Umgebung schmiermitteldicht abgedichtet. Auch dieses Dichtelement weist schwingungsdämpfende Eigenschaften auf, so dass die ungewünschte Geräuschabstrahlung minimiert ist. Die Abdichtung erfolgt ebenfalls in bevorzugter Weise axial und/oder radial.With The embodiment according to claim 4 likewise the valvetrain spaces opposite the Environment sealed lubricant seal. Also this sealing element has vibration damping properties, so that the unwanted noise emission is minimized. The seal also preferably takes place axially and / or radial.
Die Ausgestaltung gemäß Patentanspruch 5 ist ein besonders bevorzugtes Ausführungsbeispiel.The Embodiment according to claim 5 is a special preferred embodiment.
Mit der Ausgestaltung gemäß Patentanspruch 6 übernimmt die Hülse nochmals eine weitere Funktionalität und dient der einfachen Befestigung eines Lagerdeckels des Ventiltriebs an den Lagerstuhl. Ein separates Befestigungsmittel, wie z. B. eine Schraube, kann entfallen.With the embodiment according to claim 6 takes over the sleeve again another functionality and is used for easy attachment of a bearing cap of the valve train to the camp chair. A separate attachment means, such. A screw, can be omitted.
Die Ausgestaltung gemäß Patentanspruch 7 ist besonders bevorzugt für direkteinspritzende, fremdgezündete Brennkraftmaschinen.The Embodiment according to claim 7 is particularly preferred for direct-injection, spark-ignited Internal combustion engines.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispieles in einer einzigen schematischen Figur näher erläutert.in the The following is the invention with reference to a particularly preferred embodiment explained in more detail in a single schematic figure.
