KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die vorliegende Erfindung besteht in einer Pumpe, auf deren mit Spielraum in dem Steigrohre geführten Kolben nur beim Niedergange Kraft ausgeübt wird, während die Auf bewegung theils durch die beim Niedergange aufgespeicherte Kraft, theils durch die Trägheit der aufsteigenden Flüssigkeitssäule bewirkt wird.The present invention consists in a pump on its with clearance in the riser pipes guided piston force is only exerted during the downstroke while the movement is on partly through the force accumulated when going down, partly through inertia the rising column of liquid is effected. Die Pumpe besteht, wie aus Fig. 1 und 2 ersichtlich, aus dem mit Ausflufs E versehenen Steigrohr .4, dem in diesem undicht geführten Kolben P mit Gestänge und einem auf der Bodenfiäche mit einem Einlassventil C versehenen Windkessel B. Wird der Kolben P in dem Steigrohr schnell niedergedrückt, so wird er die unter ihm stehende Flüssigkeit vor sich her in den Windkessel drücken (wobei infolge der Schnelligkeit der Niederbewegung nur sehr wenig Flüssigkeit am Kolben vorbeigelangen kann), und hierbei die bei b im Windkessel befindliche Luft stark comprimiren. Wird nun der Kolben freigegeben, so dehnt sich die comprimirte Luft aus und drückt die Flüssigkeit in dem Steigrohr hoch und an dem langsamer aufsteigenden Kolben P vorbei. Die Trägheit der hochgedrückten Flüssigkeitssäule bewirkt nun ein Oeffnen des Ventiles C (Fig. 2) und reifst eine der oben abfliefsenden Flüssigkeitsmenge gleiche Menge in den Windkessel. Die Füssigkeitssäüle nimmt dann wieder ihre ursprüngliche Gleichgewichtslage ein, und das Ventil C wird geschlossen. In gewissen Fällen kann das bei b befindliche Luftkissen in bekannter Weise auch durch Federn oder elastische Wände ersetzt werden.The pump is, as shown in Fig. 1 and 2, from the provided with Ausflufs E riser .4, which is in this leaking guided piston P with linkage and a provided on the Bodenfiäche with an intake valve C air chamber as the piston P in If you quickly depress the riser pipe, it will push the liquid below it into the air chamber (whereby, due to the rapidity of the downward movement, very little liquid can get past the piston), and thereby strongly compress the air in the air chamber at b. When the piston is now released, the compressed air expands and pushes the liquid up the riser pipe and past the piston P, which rises more slowly. The inertia of the pushed-up liquid column now causes valve C (Fig. 2) to open and an amount equal to the amount of liquid flowing off above matures into the air chamber. The liquid column then resumes its original equilibrium position and valve C is closed. In certain cases, the air cushion at b can also be replaced in a known manner by springs or elastic walls. Patent-Ansρrüch:Patent claim: Pumpe ohne Druckventil, dadurch gekennzeichnet, dafs das untere Ende des Steigrohres A in einen mit Einlafsventil C versehenen Windkessel B mündet, wobei das Wasser dadurch gehoben wird, dafs der undicht gehende Kolben P beim Niedergang eine Verdichtung der Luft im Windkessel B veranlafst, so dafs das Wasser bei Umkehrung der Kolbenbewegung durch den Luftdruck im Windkessel gehoben wird und an dem undichten Kolben vorbei ausströmt.Pump without pressure valve, characterized in that the lower end of the riser pipe A opens into an air vessel B provided with an inlet valve C, the water being lifted by the fact that the leaking piston P causes the air in the air vessel B to be compressed as it descends, so that When the piston movement is reversed, the water is lifted by the air pressure in the air chamber and flows out past the leaky piston.
