Mit dem im Gehäuse b geführten Kolbenschieber α ist der Belastungshebel d in der üblichen Weise verbunden. Das Belastungsgewicht c aber dieses Hebels verschiebt sich selbstthätig infolge der Auf- und Abwärtsbewegung des Kolbens, also in Uebereinstimmung mit dem jeweilig auf das Ventil wirkenden Druck.The loading lever d is connected in the usual way to the piston slide α guided in the housing b. The loading weight c of this lever moves automatically as a result of the upward and downward movement of the piston, that is, in accordance with the pressure acting on the valve.
Das Gewicht c ist nämlich mit der endlosen Kette oder Schnur f verbunden, welche über die am Hebel d gelagerten Scheiben g und h gelegt ist. Die Scheibe g bildet einen Theil des Zahnrades i, welches in die Zähne des Zahnbogens k greift. Bei jeder Auf- oder Abwärtsschwingung des - Hebels d dreht sich also das Zahnrad i nach der entsprechenden Richtung, und damit verschiebt sich das Gewicht c auf dem Hebel. Die Hebelbelastung ändert sich also mit jeder Verschiebung des Ventilkolbens a. The weight c is in fact connected to the endless chain or cord f , which is placed over the disks g and h mounted on the lever d . The disk g forms part of the gear wheel i, which meshes with the teeth of the dental arch k . With every upward or downward oscillation of the lever d , the gear wheel i rotates in the corresponding direction, and thus the weight c shifts on the lever. The lever load therefore changes with every displacement of the valve piston a.
Zum Ausgleichen des Gewichts der Kette / und der Scheiben h und g, sowie des Zahnrades i kann man sich eines am anderen Hebelarm angebrachten Gegengewichts Z bedienen, wenn man die Scheiben g und h nicht in der Weise auf der ganzen Hebellänge anordnen kann, dafs sie sich selbst das Gleichgewicht halten. . ■ 'A counterweight Z attached to the other lever arm can be used to balance the weight of the chain / and the disks h and g, as well as the gear wheel i , if the disks g and h cannot be arranged over the entire length of the lever in such a way that they are keep your own balance. . ■ '
Fig. ι zeigt die Vorrichtung in der Mittelstellung, von welcher Fig. 3 den Grundrifs angiebt, während Fig. 2 einen Ausschlag des Hebels d sowohl nach oben als nach unten veranschaulicht.Fig. Ι shows the device in the middle position, of which Fig. 3 indicates the Grundrifs, while Fig. 2 illustrates a deflection of the lever d both upwards and downwards.
Der Hebel d kann in irgend einer Weise mit einer beliebigen Abschabvorrichtung verbunden sein.The lever d can be connected in any way to any scraping device.
