Description

Saug- und Druckpumpe. Es ist bekannt, Pumpen dadurch zu entleeren, daß das mit dem Saugventil lose verbundene Druckventil, das sich im Kolben befindet, von außen angehoben wird, wobei es das Saugventil von seinem Sitz abhebt. Dieses Anheben des Druckventils erfolgte bisher durch eine Kette oder eine Stange. Dies läßt sich aber bei Saug- und Druckpumpen, die durch. einen Deckel abgeschlossen sind, schlecht durchführen. Hierfür soll nun die Vorrichtung nach der Erfindung Verwendung finden, indem der Kolben, .wenn die Pumpe entleert werden soll, über seine normale Endstellung angehoben wird, was sich nach Entfernen eines Anschlages für den Schwengel bewerkstelligen läßt. In diesem Falle stößt ein an das im Kolben sitzende Druckventil aasgelenkter Doppelhebel gegen einen Anschlag, wodurch der Doppelhebel gedreht wird und dadurch das Druckventil von seinem Sitz hebt, das nun seinerseits das Saugventil anhebt.Suction and pressure pump. It is known to drain pumps by that the pressure valve, which is loosely connected to the suction valve and located in the piston, is raised from the outside, lifting the suction valve from its seat. This Up until now, the pressure valve has been raised by means of a chain or a rod. this but can be used with suction and pressure pumps that through. a lid completed are performing badly. For this purpose, the device according to the invention is now intended Can be used by the plunger, .when the pump is to be emptied, over its normal end position is raised, which occurs after removing a stop for the handle can be done. In this case it comes across a on the pressure valve located in the piston, articulated double lever against a stop, whereby the double lever is rotated and thereby the pressure valve from its seat lifts, which in turn lifts the suction valve.

Abb. i stellt einen Querschnitt eines Pumpengehäuses dar, mit Kolben in normaler Endstellung.Fig. I shows a cross section of a pump housing, with pistons in normal end position.

Abb. z zeigt den Kolben in einer Lage, welche den Doppelhebel in Tätigkeit gesetzt hat.Fig. Z shows the piston in a position which the double lever in action has set.

Indem der Schwengel i (Abb. i) von der gezeichneten Lage bis in die gestrichelte Lage geführt wird, wird in dem Pumpenkörper z der Kolben 3 auf und ab bewegt. Dabei öffnen sich die Saug- und Druckventile q. und 5 abwechselnd und lassen die Flüssigkeit von dem Saugrohr nach dem Druckrohr 7 ,gelangen. Wird .aber der Anschlag 8, der die Begrenzung des Schwengels bewirkt, entfernt, so kann dieser die Lage einnehmen nach Abb. z. Der Kolben 3 wird höher gehoben als normal, und ein an diesem Kolbengestänge angebrachter Doppelhebel 9 stößt an einem am Zylinderdeckel fest angebrachten Anschlag io an. Hebel 9 macht einen Ausschlag und hebt dadurch das Druckventil s an. Da nun eine Verbindung zwischen dem Ventil 5 und q. vorhanden ist, so wird auch das Saugventil ;l gehoben. Diese Verbindung i i kann eine Kette o.-dgl. sein, welche bei dem normalen Hub nach Abb. i lose herunterhängt und erst in der außergewöhnlichen Lage (Abb. -) angezogen wird.By moving the handle i (Fig. I) from the position shown to the dashed position is performed, the piston 3 is in the pump body z and off moves. The suction and pressure valves q open. and 5 alternate with and allow the liquid to pass from the suction pipe to the pressure pipe 7. Will. But the stop 8, which causes the limitation of the lever, removed, so this can take the position according to fig. The piston 3 is raised higher than normal, and a double lever 9 attached to this piston rod strikes one on the cylinder cover fixed stop ok. Lever 9 deflects and lifts the pressure valve s on. Since there is now a connection between the valve 5 and q. available the suction valve; l is also raised. This connection i i can be a chain or the like which hangs loosely with the normal stroke according to Fig. i and only in the exceptional position (Fig. -) is attracted.
