KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die in den beiliegenden Zeichnungen dargestellte Pumpenbauart bezweckt den sicheren, zwanglä'ufigen Schlufs des Saugventiles bei den höchst zulässigen Umdrehungszahlen.The purpose of the pump design shown in the accompanying drawings is to ensure safe, inevitable closing of the suction valve at the highest permissible number of revolutions.
Dieselbe besteht aus der Pumpe mit dem Taucherkolben b, dem Saugventil α mit dem Kolben c, dem am Taucherkolben b befindlichen Kolben d mit Bohrung (Kanal f) und den Cylindern e und ex. The same consists of the pump with the plunger b, the suction valve α with the plunger c, the piston d located on the plunger b with a bore (channel f) and the cylinders e and e x .
Die Wirkungsweise ist folgende: Sobald der beim Rückwärtsgang saugend wirkende Taucherkolben b beinahe in die Todtlage gekommen ist, tritt der Kolben d in den Cylinder e ein, preist die Flüssigkeit durch den Kanal f nach dem Cylinder O1, drückt hier auf den Kolben c und treibt diesen heraus, wodurch das Saugventil α sicher geschlossen wird.The mode of operation is as follows: As soon as the plunger piston b , which is sucking in reverse gear, has almost come to its dead position, the piston d enters the cylinder e , presses the liquid through the channel f to the cylinder O 1 , here presses on the piston c and drives this out, whereby the suction valve α is safely closed.
Aufserdem wird die Schliefsung und Eröffnung des Saugventils α noch durch das bei schnellem Gange der Pumpe energisch auftretende Beharrungsvermögen desselben unterstützt. In addition, the closing and opening of the suction valve α is supported by the inertia of the pump, which occurs energetically when the pump is running rapidly.
Claims (1)
Steuerung für unmittelbar am Taucherkolben und gleichachsig mit diesem angeordnetes, sich selbstthätig öffnendes Saugventil mit hydraulischem Kraftschlufs, dadurch gekennzeichnet, dafs kurz vor Ende des Saughubes ein hohler, am Kolben (b) befindlicher Kolben (d) in einen Hohlraum (e) an der Pumpenkammer eindringt und hierdurch einen Flüssigkeitsdruck erzeugt, welcher sich durch die Bohrungen (d und f) nach dem mit dem Kolben (b) verbundenen Cylinder (e-J fortpflanzt und in diesem auf den am Saugventil (α) angeordneten Kolben (c) prefst.Patent claim:
Control for automatically opening suction valve with hydraulic power supply, which is arranged directly on the plunger and coaxially with it, characterized in that shortly before the end of the suction stroke a hollow piston (d) located on piston (b) is inserted into a cavity (e) in the pump chamber penetrates and thereby generates a liquid pressure, which propagates through the bores (d and f) to the cylinder (eJ connected to the piston (b) and in this cylinder (eJ) on the piston (c) arranged on the suction valve (α) .
