PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING KLASSE 14: Dampfmaschinen.CLASS 14: Steam Engines. Patentirt im Deutschen Reiche vom 4. März 1881 ab.Patented in the German Empire on March 4, 1881. Die Steuerwelle A macht die gleiche Anzahl von Umdrehungen wie die Dampfmaschine. Auf derselben sitzen zwei Excenter, von denen jedes ein Einlafs- und ein Auslafsventil steuert. Das Auslafsventil wird auf bekannte Weise durch Stange und Hebel bewegt, das Einlafsventil wie folgt:The control shaft A makes the same number of revolutions as the steam engine. On the same sit two eccentrics, each of which controls an inlet and an outlet valve. The outlet valve is moved in a known manner by rod and lever, the inlet valve as follows: Der Excenterring des Excenters α schwingt um den festen Punkt d der Stange c d, während die das Einlafsventil bewegende Stange e mit ihrem einen Ende durch einen Winkelhebel mit dem Ventil verbunden ist, wogegen ihr anderes Ende mit der am Excenter festsitzenden Stange/" vermittelst eines Drehbolzens in der Art verbunden ist, dafs der Drehpunkt auf der Stange/" durch den Regulator verschiebbar ist. Je nachdem nun die Stange e am Fufse oder an der Spitze von / angreift, ist die durch das Ventil gegebene Cylinderfüllung kleiner oder gröfser, und zwar sind alle Füllungen zwischen ο und 5/8 erreichbar.The eccentric ring of the eccentric α swings around the fixed point d of the rod cd, while one end of the rod e moving the inlet valve is connected to the valve by an angle lever, while its other end is connected to the rod fixed on the eccentric by means of a pivot pin is connected in such a way that the pivot point on the rod / "is displaceable by the regulator. Depending on the rod is now e acts at the foot or at the top of /, given by the valve is less than or Cylinderfüllung gröfser, namely all fillings between ο and 5/8 are achievable. Pateνt-AnSpruch:Pateνt claim: Die Bewegung der beiden Dampfeinlafsventile der Ventilsteuerung in der durch die Zeichnung ersichtlichen Weise durch je ein Kreisexcenter, dessen Angriffspunkt an der Ventilstange auf einer Geraden durch den Regulator verschiebbar ist, während der Excenterbügel selbst durch einen in dieser Geraden liegenden Bolzen auf einem Bogen geführt wird.The movement of the two steam inlet valves of the valve control in the through the drawing evident way by a circle center, whose point of application on the valve rod a straight line through the regulator, while the eccentric bracket itself through a bolt lying in this straight line is guided on an arc.
