Description

Vorrichtung zum Einstellen des Ventilspieles bei Brennkraftmaschinen Die Erfindung betrifft eine Vorrichtung zum Einstellen des Ventilspieles bei Brennkraftmaschinen mit Hilfe von auswechselbaren Zwischenlagen, welche auf dem Ende des Ventilschaftes gehalten werden. Aufgabe der Erfindung ist es, die bekannte Haltekappe der Zwischenlagen durch einen einfacher herstellbaren Bauteil zu ersetzen und dabei möglichst noch an Bauhöhe zu gewinnen. Schließlich bedingt ja jeder eingesparte Millimeter Bauhöhe eine Verringerung .des Gewichtes und der Gestehungskosten des Motors.Device for adjusting the valve clearance in internal combustion engines The invention relates to a device for adjusting the valve clearance in internal combustion engines with the help of interchangeable intermediate layers, which are on the end of the valve stem being held. The object of the invention is the known retaining cap of the intermediate layers to be replaced by a component that is easier to manufacture and, if possible, still to gain in height. After all, every millimeter saved results in installation height a reduction in the weight and cost of the engine.

Die Erfindung besteht darin, daß die Zwischenlage durch ein Druckstück gehalten wird, welches in die Bohrung der Klemmkeile des Ventilfedertellers eingeführt wird. Das glatte, zylindrische Druckstück ist natürlich billiger als die bisher verwendete Haltekappe. Außerdem ergibt sich bei einer im vorstehenden Sinne ausgebildeten Ventilsteuerung gegenüber einer Haltekappe vergleichbarer Bodenstärke ein Gewinn von mehreren Millimetern Bauhöhe.The invention consists in that the intermediate layer by a pressure piece is held, which is inserted into the bore of the clamping wedges of the valve spring plate will. The smooth, cylindrical pressure piece is of course cheaper than the previous one used retaining cap. In addition, it results in a trained in the above sense Valve control is a plus compared to a retaining cap with a comparable base thickness several millimeters high.

Bei einer Ausführungsform der Erfindung wird an Stelle von Zwischenlagen verschiedener Dicke jeweils lediglich ein Druckstück von passender Dicke verwendet.In one embodiment of the invention, instead of intermediate layers different thickness, only one pressure piece of the appropriate thickness is used.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung in Form eines Längsschnittes durch die im wesentlichen der Ventilsteuerung dienenden. Teile einer Brennkraftmaschdne dargestellt.In the drawing is an embodiment of the invention Device in the form of a longitudinal section through essentially the valve control serving. Parts of an internal combustion engine shown.

Der Schaft 1 des im übrigen nicht dargestellten Ventils wird in einer Ventilführung 2 geführt, welche im Zylinderkopf 3 einer Brennkraftmaschine befestigt ist. Der Ventilschaft 1 besitzt in der Nähe seines Endes 4 eine Umfangsnut 5. In diese greift ein innen angeordneter Bund 6 der Klemmkeile 7 des Federtellers 8 der Ventilfeder 9 ein. Auf dem Ende 4 des Ventilschaftes 1 ist eine Zwischenlage 10 und auf dieser ein Druckstück 11 lose angeordnet. Zwischenlage und Druckstück werden in radialer Richtung an der Innenwand der Klemmkeile? des Federtellers 8 gehalten. In axialer Richtung sind sie durch den Schwinghebel 12 gesichert, welcher um eine Achse 13 schwingbar im Zylinderkopf 3 gelagert ist und von dem Nocken 14 einer obenliegenden Nockenwelle 15 betätigt wird. Statt Zwischenlagen unterschiedlicher Dicke und Druckstücke brauchen beim Zusammenbau der Ventilsteuerungsteile auch nur Druckstücke passender Dicke bereitgelegt zu werden, um den Zweck der Erfindung zu verwirklichen.The shaft 1 of the valve otherwise not shown is in a Out valve guide 2, which is fixed in the cylinder head 3 of an internal combustion engine is. The valve stem 1 has a circumferential groove 5 in the vicinity of its end 4 this engages an internally arranged collar 6 of the clamping wedges 7 of the spring plate 8 of the Valve spring 9 a. On the end 4 of the valve stem 1 there is an intermediate layer 10 and on this a pressure piece 11 is loosely arranged. Interlayer and pressure piece are in the radial direction on the inner wall of the clamping wedges? of the spring plate 8 held. In the axial direction they are secured by the rocker arm 12, which by a Axis 13 is pivotably mounted in the cylinder head 3 and from the cam 14 an overhead Camshaft 15 is actuated. Instead of intermediate layers of different thicknesses and pressure pads only need more suitable pressure pieces when assembling the valve control parts Thickness to be laid in order to achieve the purpose of the invention.
