Zweck der dargestellten Einrichtung ist, die Anspannung der Kolbendichtungsringe zu ermöglichen, ohne dafs der Kolben aus einander genommen zu werden braucht.The purpose of the device shown is to enable the piston sealing rings to be tightened, without the piston needing to be taken apart.
Die beiden Kolbenhälften A und B sind durch die vier Kolbenschrauben ä verbunden; r r sind zwei Kolbendichtungsringe, D ist eine Welle mit zwei Excentern E E. Die beiden Kolbenfedern FF können entweder, nach Fig. 1, als zweiarmige oder, nach Fig. 2, als einarmige Hebel ausgebildet sein.The two piston halves A and B are connected by the four piston screws ä; r r are two piston sealing rings, D is a shaft with two eccentrics E. The two piston springs FF can either, according to FIG. 1, be designed as two-armed or, according to FIG. 2, as one-armed levers.
Das aus dem Kolben herausragende Ende der Excenterwelle D ist zum Vierkant ausgebildet. Durch eine auf das Ende aufgesetzte Kurbel kann die Excenterwelle in der Richtung des Pfeiles gedreht und hierbei durch die Excenter eine Bewegung der Federn FF bewirkt werden. Die letzteren drücken nun mittelst der Bolzen b b auf die Keile k k und bewirken durch diese auf bekannte Weise das Anspannen der Kolbendichtungsringe r r. Das auf der Excenterwelle D sitzende Sperrrad S hindert die Welle am Zurückgehen nach erfolgter Spannung der Federn.The end of the eccentric shaft D protruding from the piston is square. With a crank placed on the end, the eccentric shaft can be rotated in the direction of the arrow and the eccentrics cause a movement of the springs FF . The latter now press by means of the bolt bb on the wedges kk and thereby cause the piston sealing rings r r to be tightened in a known manner. The ratchet wheel S sitting on the eccentric shaft D prevents the shaft from retreating after the springs have been tensioned.
Der Vorgang kann stattfinden, ohne dafs man nöthig hätte, den Kolben aus einander zu nehmen. Damit man dabei auch den Cylinderdeckel C nicht abzunehmen braucht, ist in demselben eine in der Richtung der Excenterwelle sitzende, durch eine Verschraubung V verschliefsbare Oeffnung angebracht, durch welche die Kurbel eingesteckt wird.The process can take place without having to take the flask apart. So that the cylinder cover C does not have to be removed, an opening, which is seated in the direction of the eccentric shaft, can be closed by a screw connection V and through which the crank is inserted, is attached.
