Description

Das Hauptpatent betrifft eine Pumpeinrichtung, deren Pumporgan f (Membran, Kolben oder Wand) derartig bemessen ist, daß die Erzielung eines hohen Vakuums durch einen einzigen Schlag oder Zug möglich ist. Um den Pumpakt durch einen einzigen Schlag ausüben zu können, wird das Pumporgan f in die Stellung des größten. Volumens durch eine Feder g gedrückt. Jeder Druck auf Knopf i entgegen der Feder g verkleinert das Volumen der Pumpe, wobei der Überdruck über den Gummiring d entweicht. Läßt der Druck (oder Schlag) auf den Knopf i nach, so schnellt das Pumporgan f, dem Druck der Feder g folgend, nach oben, wodurch der Pumpakt vollzogen wird. Hierbei entsteht im Innern der Pumpe ein Vakuum, welches in einer bestimmten Beziehung. zu a) dem Hubvolumen des Pumporgans f, b) der im Innern der Pumpe, einschließlich des Einmachgutes, herrschenden Spannung, c) der Kraft der Feder g steht. Die Resultierende aus diesen Relationen läßt sich messen und in einfacher Weise direkt aus der je- weiligen Stellung des Pumpenstiels schließen.The main patent relates to a pumping device whose pumping element (membrane, piston or wall) is dimensioned in such a way that a high vacuum can be achieved by a single blow or pull. In order to be able to perform the pumping act with a single stroke, the pumping element f is in the position of the largest. Volume pressed by a spring g. Each press of button i against spring g reduces the volume of the pump, with the excess pressure escaping via rubber ring d. If the pressure (or blow) on the button i decreases, the pumping element f, following the pressure of the spring g, snaps upwards, whereby the pumping act is carried out. This creates a vacuum inside the pump, which in a certain relationship. to a) the stroke volume of the pump element f, b) the tension prevailing inside the pump, including the canned goods, c) the force of the spring g. The resultant from these relations can be measured and deduced in a simple manner directly from the respective position of the pump handle.

Zum Zwecke der Ablesung ist daher der Pumpenstiel erfindungsgemäß mit einer Vakuumskala ausgestattet. Gegenstand der vorliegenden Erfindung ist also eine Pumpeinrichtung, bestehend aus einer Pumpkammer a mit einer veränderlichen Membran f, die unter der Einwirkung einer durch Bewegung des Pumpenstiels h veränderlichen Federspannung steht (nach Patent 831797) und da,ß sich das Maß des nach deni Pumpakt in, der Pumpkammer d vorhandenen Vakuums an einer auf dem Pumpenstiel h angebrachten Skala ablesen läßt.For the purpose of reading, the pump handle is therefore equipped according to the invention with a vacuum scale. The subject of the present invention is therefore a pumping device, consisting of a pumping chamber a with a variable membrane f, which is under the action of a spring tension which can be changed by moving the pump handle h (according to patent 831,797) and there, ß the amount of the pumping act in, the pump chamber d can be read off the existing vacuum on a scale attached to the pump handle h.

In der Zeichnung ist noch ein Hebel p zu sehen. Dieser gestattet in bekannterWeise (Patent89i 179) in Verbindung mit einem Knebel o eine Blockierung des Pumpenstengels h in Spannstellung, um auf diese Weise eine schußartige Auslösung des Pumpaktes zu ermöglichen. Zu diesem Zwecke fällt der Hebel p durch sein Eigengewicht - in dem Augenblick herunter, in welchem die Nut n die Höhe des Knebels o erreicht hat, da dann der unrunde Knebel o nicht mehr von dem Pumpenstengel h in seiner Bewegung gehindert wird. Hierdurch wird der Pumpenstiel h in seiner gespannten Lage so lange blockiert, bis er, durch Anheben des I@ebels p freigegeben dem Druck der Feder g folgend, nach oben schnellen. kann. Dann wird der innere Druck an der Skala des Pumpenstiels h abgelesen.A lever p can also be seen in the drawing. This allows in known way (patent 89i 179) in connection with a toggle o a blocking of the pump stem h in the cocked position in order to trigger a shot-like action in this way to enable the pumping act. For this purpose, the lever p falls due to its own weight - down at the moment when the groove n reaches the height of the toggle o has, since then the non-round toggle o no longer moves from the pump handle h is prevented. As a result, the pump handle h is so long in its tensioned position blocked until it releases the pressure of the spring g by lifting the lever p following, snap up. can. Then the internal pressure on the scale of the Read off pump handle h.
