Abstract
Ventil für Brennkraftmaschinen, mit zwei koaxialen Ventilfedern, die sich an gegenüberliegenden ersten und zweiten Ventilfedertellern abstützen, wobei der erste Ventilfederteller mittels eines Ventilkeils festgesetzt ist und der zweite Ventilfederteller sich an einem Zylinderkopf abstützt, wobei zumindest der erste Ventilfederteller (6) Ausnehmungen (14 und 15) für die äußere Ventilfeder (4) und die innere Ventilfeder (5) aufweist, welche äußere Ventilfeder (4) und innere Ventilfeder (5) von einer ersten Schräge (17) und zweiten Schräge (18) der Ausnehmungen (14 und 15) zentriert werden, dadurch gekennzeichnet, dass die äußere Ventilfeder (4) und die innere Ventilfeder (5) im eingebauten Zustand eine gleiche Länge (L) aufweisen.Valve for internal combustion engines, with two coaxial valve springs which are supported on opposite first and second valve spring plates, the first valve spring plate being fixed by means of a valve wedge and the second valve spring plate being supported on a cylinder head, with at least the first valve spring plate (6) having recesses (14 and 15) for the outer valve spring (4) and the inner valve spring (5), which outer valve spring (4) and inner valve spring (5) from a first slope (17) and second slope (18) of the recesses (14 and 15) are centered, characterized in that the outer valve spring (4) and the inner valve spring (5) have the same length (L) in the installed state.
Description
Die Erfindung betrifft ein Ventil für ein Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve for an internal combustion engine according to the preamble of
Aus den beiden Druckschriften
Ein bekanntes Ventil für eine Brennkraftmaschine,
Aufgabe der Erfindung ist es, einen Ventilfederteller für ein Ventil einer Brennkraftmaschine zu schaffen, der zum einen bezüglich Gewicht optimiert ist und zum anderen eine funktionsgerechte Zentrierung für zwei koaxial zueinander angeordnete Ventilfedern gewährleistet.The object of the invention is to provide a valve spring plate for a valve of an internal combustion engine, which is optimized for a weight and on the other hand ensures a functionally correct centering for two coaxially arranged valve springs.
Erfindungsgemäß wird dies Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention this object is achieved by the features of
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die äußere und die innere Ventilfeder durch die Ausnehmungen und die Schrägen des Ventiltellers wirkungsvoll zentriert werden. Dabei lässt sich der Ventilteller durch die dimensionsoptimierten Ausnehmungen und Schrägen hinsichtlich Gewicht günstig gestalten, was das Bestreben die Massen zu reduzieren unterstützt.The advantages achieved by the invention are to be seen in the fact that the outer and the inner valve spring are effectively centered by the recesses and the slopes of the valve disk. The valve disc can be made favorable by the dimension-optimized recesses and bevels in terms of weight, which supports the effort to reduce the masses.
In der Zeichnung, die eine einzige Figur wiedergibt, wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert wird.In the drawing, which shows a single figure, an embodiment of the invention is shown, which will be explained in more detail below.
Von einer Brennkraftmaschine ist lediglich ein Ventil
Auf der den Ventilfedern
Schließlich beträgt das Maß zwischen der ersten äußeren Begrenzungsebene
