Description

Ventilsteuerung für Verpuffungskraftlnaschinen. Die Erfindung besteht in einer neuen Ventilsteuerung für Verpuffungskraftmaschiuen. Bei diesen werden die über den meist stehenden Zylindern angeordneten beiden Ventile gewöhnlich vermittels zweiarrniger Hebel, die von einer Nockenwelle aus durch Stoßstangen bewegt werden, von oben gesteuert. Dabei sind in der Regel für jedes Ventil ein Hebel mit Lagerbock und eine Stoßstange vorbanden. Es ist auch eine Ventilsteuerung mit von oben gesteuerten Ventilen bekannt, bei der beide Ventile von nur einem Ventilhebel gesteuert werden. Dieser gegenüber besteht die in den Abb. i bis 3 dargestellte Steuerung darin, daß der Ventilhebel nur an den Enden der Ventilschäfte und am Ende der antreibenden Steuerstange angelenkt ist. Die Nockenwelle n bewegt die Steuerstange s, welche den die beiden Ventile betätigenden Hebel v steuert. Wenn die Nockenwelle vermittels des Nockensizl die Stange s nach unten zieht, so öffnet dadurch der Hebel v als einarmiger I-Lcbe1 Auslaßventil a; bewegt die Nockenwelle vermittels des Nockens ia, die Stange nach oben, so öffnet der Hebel v als zweiarmiger Hebel das Einlaßventil e.Valve control for deflagration engines. The invention exists in a new valve control for deflagration engines. With these will be the two valves arranged above the mostly standing cylinders usually by means of two-armed levers that are moved by a camshaft through bumpers, controlled from above. As a rule, there is a lever with a bearing block for each valve and tied up a bumper. There is also a valve control with top controlled Known valves in which both valves are controlled by only one valve lever. This opposite is the control shown in Figs. I to 3 is that the valve lever only at the ends of the valve stems and at the end of the driving Control rod is hinged. The camshaft n moves the control rod s, which controls the lever v actuating the two valves. When the camshaft mediates of the Nockensizl pulls the rod s downwards, the lever v opens as a result one-armed I-Lcbe1 exhaust valve a; moves the camshaft by means of the cam ia, the rod up, the lever v opens the inlet valve as a two-armed lever e.

Die Abb. 5 und 6 stellen noch eine Steuerung mit nur einem Nocken dar. Die Arbeitsweise ist daraus ohne weiteres deutlich ersichtlich. Wenn nur ein Nocken verwendet wird, so müssen die beiden Druckrollen, wie in den Abbildungen, unsymmetrisch zu dem Drehpunkt des Hebels, an dem sie befestigt sind, angebracht werden, weil 'sonst die Ventile zu ungleichen Hub haben, da ja der Ventilhebel als ein- und zweiarmiger Hebel wirkt.Figs. 5 and 6 show a control with only one cam The mode of operation is clearly evident from this. If only one Cam is used, the two pressure rollers must, as shown in the figures, mounted asymmetrically to the pivot point of the lever to which they are attached because 'otherwise the valves will have too unequal stroke, since the valve lever as one- and two-armed lever works.
