 durch das mit dem Ventil i versehene Saugrohr I statt, während das Fortdrücken der Flüssigkeit durch ein in dem Raume zwischen den beiden Kolben C und C1 mündendes   Druckrohr J'erfolgt. Die Wirkungsweise   dieser Einrichtung entspricht der Arbeitsweise der in den Fig. 1 und 2 dargestellten Pumpe.

   Die Kolben C und Ci bilden einen   Doppol-   kolben, der dem Hohlkolben C der Pumpe nach   den Fig. l   und 2 entspricht, bei welch' letzterem die Seitenwandung nur zur Verbindung der unteren und oberen Fläche des Kolbens dient. Bei der Ausführungsform nach Fig. 3 entfällt diese Soitonwandung ; sie ist durch die Stange E crsetzt, die die beiden Kolben C und Cl miteinander verbindet. Die Pumpe nach Fig. 3 kann ebenso wie die nach den Fig. 1 und 2 zum Kraftausgleiche mit einem Gegengewichte versehen oder mit einer Wassersäule verbunden sein ; in letztcrem   Falll1 wird   der Boden des Zylinders durch ein Rohr L1 mit dem Druckrohre J1 verbunden. 



   Wenn zwei Pumpen der beschriebenen Art, entweder nach den Fig. 1 und 2 oder nach Fig. 3, gekuppelt sind, so kann der Kraftausgleich in einfacher Weise dadurch erzielt

 has to balance the weight of the water mass on the downward stroke. This has the advantage that a regular and uninterrupted expenditure of force is required to operate the pump, while the previous pump is operated back and forth
 EMI2.2
 through the suction pipe I provided with the valve i, while the liquid is expelled through a pressure pipe J 'opening into the space between the two pistons C and C1. The operation of this device corresponds to the operation of the pump shown in FIGS. 1 and 2.

   The pistons C and Ci form a double piston which corresponds to the hollow piston C of the pump according to FIGS. 1 and 2, in which the latter the side wall only serves to connect the lower and upper surfaces of the piston. In the embodiment according to FIG. 3, this wall is omitted; it is set by the rod E, which connects the two pistons C and Cl. The pump according to FIG. 3, like that according to FIGS. 1 and 2, can be provided with a counterweight or connected to a water column for force compensation; in the latter case, the bottom of the cylinder is connected to the pressure pipe J1 by a pipe L1.



   If two pumps of the type described, either according to FIGS. 1 and 2 or according to FIG. 3, are coupled, the force compensation can thereby be achieved in a simple manner
