oder einen DifFerentialkolben.or a differential piston.

Vorliegende Erfindung bezweckt ein schnelles Schliefsen und Oeffhen der Saugventile von durch Wasserdruck betriebenen Pumpen mit zwei sich gegenseitig und sich selbst steuernden Systemen, und zwar durch Anwendung von Wasserdruckkolben.The present invention aims to quickly close and open the suction valves of pumps operated by water pressure with two mutually and self-regulating Systems, through the use of water pistons.

Es soll dabei jedoch die Anwendung einer besonderen Steuerung oder einer besonderen Druckpumpe vermieden werden. Ferner soll, namentlich da diese Art Pumpen meist als Wasserhaltungen für Bergwerke benutzt werden, die Verwendung des meist sehr unreinen, von der Pumpe selbst geförderten Wassers vermieden werden.However, it is intended to use a special control or a special one Pressure pump can be avoided. Furthermore, especially since this type of pump is usually used as a Dewatering for mines are used, the use of the mostly very impure, water pumped by the pump itself can be avoided.

Um dies zu erreichen, wird jedes Saugventil mit zwei verschieden grofsen bezw. einem Differentialkolben direct oder indirect verbunden. Die gröfseren dieser Kolben stehen in ständiger Verbindung mit der Kraftwasserrückleitung, die kleineren mit dem Inneren der Kraftwassercylinder ihrer eigenen Seite.To achieve this, each suction valve is equipped with two different sizes or one Differential pistons connected directly or indirectly. The larger of these pistons are standing in constant connection with the power water return line, the smaller ones with the interior of the Power water cylinders of their own side.

Bewegen sich nun die Förderplunger nach links (C1), so herrscht innerhalb des linken Kraftwassercylinders ^1 der Druck der Hochdruckleitung und innerhalb des rechten (d2), der der Rückleitung und es wird links das Saugventil durch den Druck der Hochdruckleitung auf den kleinen Kolben a, welcher gröfser ist als der der Rückleitung auf den Kolben b, zugedrückt. Während derselben Bewegung wird auf der rechten Seite c2, da hier beide Kolben unter dem Drucke der Rückleitung stehen, das Ventil durch den gröfseren Kolben b offen gehalten.If the delivery plunger now move to the left (C 1 ), the pressure of the high pressure line prevails inside the left power water cylinder ^ 1 and inside the right one (d 2 ), that of the return line and the suction valve becomes the left due to the pressure of the high pressure line on the small one Piston a, which is larger than that of the return line to piston b, is pushed shut. During the same movement, on the right-hand side c 2 , since both pistons are under the pressure of the return line, the valve is kept open by the larger piston b.

In der Zeichnung sind die Förderplunger, welche hier gleichzeitig Kraftwassercylinder sind, in der Stellung gezeichnet, in der der Schieber beginnt, links den Eintritt des Kraftwassers und rechts den Austritt desselben zu schliefsen, womit die Bewegung nach links ihr Ende erreicht. Nachdem der Schlufs der Kanäle erfolgt ist, bleibt nun das Druckverhältnifs auf die Ventilkolben und damit auch die Stellung der Ventile noch dieselbe. Sobald aber durch das nebenliegende Pumpensystem dann der Schieber noch weiter nach rechts bewegt, also umgesteuert wird, wechseln, noch ehe die Kanäle ganz geöffnet sind und die Bewegung nach rechts beginnt, die Drucke auf die kleinen Kolben α <z, so dafs links beide Kolben unter dem Drucke der Rückleitung stehen und durch den Druck auf den gröfseren Kolben b das Ventil links geöffnet und rechts durch den Hochdruck auf den kleinen Kolben der der Rückleitung auf den grofsen überwunden und das Ventil geschlossen wird.In the drawing, the feed plungers, which are also power water cylinders here, are drawn in the position in which the slide begins to close the power water inlet on the left and the outlet on the right, whereby the movement to the left reaches its end. After the channels have closed, the pressure ratio on the valve pistons and thus also the position of the valves remains the same. But as soon as the valve is moved further to the right by the adjacent pump system , i.e. is reversed, the pressure on the small pistons α <z, so that both pistons on the left, change before the channels are fully opened and the movement to the right begins are under the pressure of the return line and the valve on the left is opened by the pressure on the larger piston b and on the right by the high pressure on the small piston that overcomes the larger piston of the return line and the valve is closed.
