In diesen Cylinderkolben befinden sich ein oder mehrere Spannkolben a. Dieselben können aus verschiedenem Stoff gefertigt, in ihren Formen verschieden, auch eckig hergestellt werden. Der über oder unter dem Kolben befindliche Atmosphärendruck tritt durch die Ventile b b, Fig. ι und 3, in den Kanal e, Fig. 1 bis 3, und wirkt durch die Seitenkanäle dd auf die Kolben a, welche die Liderungen durch Prismen, Bolzen, Federn, Ringe oder dergleichen an die Cylindermäntel drücken.In these cylinder pistons there are one or more tensioning pistons a. The same can be made of different materials, different in their shapes, also made angular. The atmospheric pressure above or below the piston passes through the valves bb, Fig. Ι and 3, in the channel e, Fig. 1 to 3, and acts through the side channels dd on the piston a, which the lids through prisms, bolts, Press springs, rings or the like on the cylinder jackets.
Die Form und die Weite der Kanäle werden durch die Anzahl und den Querschnitt der Spannkolben α bemessen. Das kleine Ventil e, Fig. ι und 4, bewirkt das selbstthätige Durchlassen des durch etwaiges Undichtwerden der Spannkolben sich ansammelnden Wassers im Kolbenkörper.The shape and the width of the channels are determined by the number and cross-section of the tensioning piston α . The small valve e, Fig. 1 and 4, causes the automatic passage of the water that has accumulated in the piston body due to any leakage of the tensioning piston.
Bei Kolben, in denen Kanäle nicht angebracht erscheinen, wirken die Spannkolben f, Fig. 4, durch ihre Aussparungen g auf die Kolbenliderungen. Diese Aussparungen können gerade oder bogenförmig, auch in anderen Formen angebracht sein.In the case of pistons in which channels do not appear to be attached, the tensioning pistons f, FIG. 4, act on the piston eyelids through their recesses g . These recesses can be straight or curved, also in other shapes.
Der Querschnitt der Spannkolben α in Fig. 1 und 2 und / in Fig. 4 und 5 wird je nach dem Durchmesser der Cylinderkolben und dem auf denselben wirkenden Atmosphärendruck nach der dadurch verschieden nöthigen Spannkraft der Liderung bemessen.The cross-section of the tensioning piston α in FIGS. 1 and 2 and / in FIGS. 4 and 5 is dimensioned depending on the diameter of the cylinder piston and the atmospheric pressure acting on the same, according to the different tensioning force required for the ligation.
