Ein Tauchkolben Cb, Fig. 1 bis 4, steht in einem entsprechend langen Cylinder Cy mit Stopfbüchse St und ist mit einem Kopf Pk versehen, von welchem ein oder mehrere Tragseile oder Lastketten S ausgehen. Soll die Last gehoben werden, so mufs der Kolben abwärts gehen, und soll sie gesenkt werden, so mufs der Kolben durch den Wasserdruck gehoben werden. Das Gewicht des Kolbens ist so bemessen, dafs durch dessen Niedersinken die gegebene gröfste Last gehoben wird. Der Querschnitt des Kolbens ist dem gegebenen Wasserdruck und der gröfsten Last entsprechend. In Fig. ι ist eine Construction ohne Einschaltung einer Rollen- oder Hebelübersetzung dargestellt, bei welcher der Kolbenhub gleich dem Hube der Last, sowie das Gewicht des Kolbens, abgesehen von den Reibungswiderständen, gleich der zu hebenden gröfsten Last ist. In den Fig. 2 bis 5 sind Constructionen gezeichnet, bei welchen der Kolbenhub ein Theil der Hubhöhe der Last und das Gewicht des Kolbens ein Vielfaches der zu hebenden Last ist. Fig. 5 zeigt, wie statt eines Tauchkolbens auch ein Scheibenkolben angewendet werden kann.A plunger piston Cb, FIGS. 1 to 4, stands in a correspondingly long cylinder Cy with a stuffing box St and is provided with a head Pk from which one or more suspension ropes or load chains S extend. If the load is to be lifted, the piston must go down, and if it is to be lowered, the piston must be lifted by the water pressure. The weight of the piston is measured in such a way that the greatest given load is lifted by its sinking down. The cross-section of the piston is appropriate for the given water pressure and the greatest load. In Fig. 1 a construction is shown without the use of a roller or lever transmission, in which the piston stroke is equal to the stroke of the load and the weight of the piston, apart from the frictional resistance, is equal to the largest load to be lifted. In Figs. 2 to 5 constructions are drawn in which the piston stroke is a part of the stroke height of the load and the weight of the piston is a multiple of the load to be lifted. 5 shows how a disc piston can also be used instead of a plunger.
In den Anordnungen Fig. 2 und 3 können mehrere Tragseile oder Ketten angewendet werden, wodurch eine Sicherheit gegen Gefahr gegeben ist. Auch können solche Aufzüge nicht überlastet werden.In the arrangements of FIGS. 2 and 3, several suspension ropes or chains can be used , whereby a security against danger is given. Such elevators cannot either become overloaded.
