Die neue Vorrichtung ist in Fig. ι im Höhenlängsschnitt nach A-B der Fig. 3 dargestellt, wobei der Betriebsvorgang, der zum Speisen des Kessels führt, kenntlich gemacht ist, während in Fig. 4 eine zweite Ausführungsform ebenfalls im Höhenlängsschnitt und in kleinerem Maßstab dargestellt ist, jedoch in einem Zustand am Ende der Speisung. Fig. 2 zeigt einen Schnitt nach E-F der Fig. 3 und Fig. 3 einen Querschnitt nach C-D der Fig. 1.The new device is shown in Fig. Ι in the vertical longitudinal section according to AB of FIG. 3, the operating process that leads to the feeding of the boiler is identified, while in Fig. 4, a second embodiment is also shown in vertical longitudinal section and on a smaller scale but in a state at the end of the supply. FIG. 2 shows a section according to EF in FIG. 3 and FIG. 3 shows a cross section according to CD in FIG. 1.

Bei der neuen Vorrichtung ist ein Vakuumbehälter II durch den Kanal h unterhalb des höchsten Kesselwasserstandes mit dem Rohr y, das mit dem Dampf- und Wasserraum des Kessels in Verbindung steht, verbunden. In die Rohrleitung y ist ein Rückschlagventil m eingebaut, das eine Wasserbewegung vom Kessel verhindert. Die Wasserbewegung vom Kessel nach dem Vakuumbehälter II geschieht durch das Rohr η, welches nach Fig. 1 im Behälter III bis in die Nähe des höchsten Kessel Wasserstandes reicht, und das Rohr χ, die beide in das Rohr y münden. Durch diese Anordnung wird, da der Eintritt des Kanals h in den Vakuumbehälter II durch eine Zunge i gemäß Linie x-x unterhalb des oberen Rohr- und Kanalausflusses von η zu liegen kommt, ein plötzliches Anfüllen des Kanals h mit Wasser, sobald es über η hinaussteigt, erreicht. Der Dampfzutritt nach dem Behälter III (Fig. 1) geschieht durch die Rohrleitung fi-w, die mit dem Rohr y verbunden ist. Die Vorrichtung ist also an den Dampfund Wasserraum des Kessels angeschlossen.In the new device, a vacuum container II is connected through the channel h below the highest boiler water level with the pipe y, which is connected to the steam and water space of the boiler. A check valve m is built into the pipeline y to prevent water movement from the boiler. The water movement from the boiler to the vacuum container II occurs through the tube η, which according to FIG. 1 in the container III extends to the vicinity of the highest boiler water level, and the tube χ, both of which open into the tube y. As a result of this arrangement, since the entry of the channel h into the vacuum container II through a tongue i comes to lie below the upper pipe and channel outflow of η according to line xx , the channel h is suddenly filled with water as soon as it rises above η , achieved. The steam access to the container III (Fig. 1) occurs through the pipe fi-w, which is connected to the pipe y . The device is therefore connected to the steam and water space of the boiler.

Der Kanal a, der durch die Öffnung b mit der Wasserkammer c im Behälter III verbunden ist und mit seinem unteren Ende bis in die Nähe des niedrigsten Kesselwasserstandes reicht, bildet mit der Kammer c eine Schleife, die so lange mit Wasser gefüllt bleibt, bis der Kanal α mit seinem unteren Ende aus dem mit dem Wasser des' Kessels fallenden Wasser im Behälter III herausgetreten ist. Der Kanal d, der mit dem Dampfrohr w (Fig. i), andererseits durch die Öffnung g mit der Wasserkammer c verbunden ist und mit dieser eine Schleife bildet, steht durch den Kanal e> den eine Brause f verschließt, oberhalb des höchsten Kesselwasserstandes, also auch oberhalb des Kanalendes η mit dem Vakuumbehälter I in Verbindung.· Dieselbe Verbindung zeigt auch Fig. 4, nur sind hier die Kanäle a, d und η durch Rohrleitungen ersetzt, wo-The channel a, which is connected through the opening b with the water chamber c in the container III and extends with its lower end to the vicinity of the lowest boiler water level, forms a loop with the chamber c , which remains filled with water until the Channel α has emerged with its lower end from the water falling with the water of the 'boiler in the container III. The channel d, which is connected to the steam pipe w (Fig. I), on the other hand through the opening g to the water chamber c and forms a loop with this, is above the highest boiler water level through the channel e> which a shower f closes, also above the end of the channel η in connection with the vacuum container I. The same connection is also shown in Fig. 4, only here the channels a, d and η are replaced by pipelines, where-

in the case of container III is omitted and the pipes α and η are introduced directly into the boiler.

The vacuum containers I and II are at their lowest point S through the pipes q and q ₁ in connection with the piston space r and thus form a loop which is to be filled with water so that the piston s can never come into contact with steam. In

ίο the pipes q and q _x are the equalizing lines V ₁ and v ₂ , in which the check valves I are switched on, integrated, which then lead through the common pipe ν to the condensate trap u or to the water space of the boiler (Fig. 4).

The movements of the piston will be

transferred by a linkage to the rotary valve t , which opens or closes a steam line that is connected to the injector and thus feeds the kettle or stops the food.

So that the water in the pipe d in contact with the steam and thereby become hot does not immediately pass through the channel e to the vacuum container I, a vessel 2 serving to receive the water is switched on in the pipe d and closed as shown in FIG The vessel 5 is switched into the pipeline y for the same purpose.

Furthermore, a low water temperature is necessary to achieve a favorable vacuum the extension 3, which surrounds the jacket 4, as well as through the water chamber c, which the Jacket 1 surrounds (Fig. 4), achieved in that the jackets 1 and 4 are fed with cold water will.

The mode of operation of the device is as follows: When the boiler is fed, the water rises in the boiler and also in channel n. After reaching the upper channel section, the water passes into container III, flows through pipe χ to pipe y, whose vertical line it is fill with water up to the XX line. The channel h is then also filled with water, since it dips through the tongue i (FIG. 1) into the water part of the pipe y; also, according to FIG. 4, the entire channel h can be arranged below the maximum water level. As a result of the overpressure, the water is finely atomized from the pipe y through the channel h and the shower k and pressed into the vacuum container II, where it precipitates the steam located there and thus creates a negative pressure. This negative pressure in the tank II then suction of the water from the room R through the tube q ₁ result, so that movement of the piston s in the opposite position illustrated in Fig. 1 is effected, wherein the rotary vane t the Dämpfdurchgang to Injector locks.

During the mean water level in the boiler, the channel or the tube α and the chamber c are filled with water, while the water level in channel d and according to FIG. 1 also in container III is at the same level as that of the boiler. If, however, the lowest water level occurs in the boiler, so that steam can get into the channel α , the same passes through the opening b (FIG. 2) into the chamber c. In this case, so much water is transferred from chamber c through opening g (FIGS. 1 and 2) to channel d until the water levels in c and d are the same (FIG. 2), namely significantly higher than the highest boiler water level . Accordingly, the channel e, which the shower f closes, is also filled with water, which is pressed into the vacuum container I by the overpressure. In Fig. 4 this loop-like pipe guide a, c and d is clearly shown, and the same effect applies to this. If water now passes through the shower f into the steam-filled space I, as illustrated in FIG. 1, a negative pressure arises in the same, which causes the water to be sucked in from the piston space r through the pipe q and thus a movement of the piston s to the left, which opens the steam passage after the injector.

When the mean (normal) boiler water level enters, the water in the vacuum tanks I and II is released from the tanks through the pipes V ₁ , V ₂ and ν to the outside (Fig. 1) or to the steam entering through the channels e and h the boiler (Fig. 4) out. The check valves I in V ₁ and V ₂ prevent steam from entering the vacuum containers I and II. For the controlled discharge of the water that is deposited in these containers, a condensate trap u (Fig. 1) is connected to the outside of the pipeline υ, or the precipitated water according to FIG. 4 is passed directly through the pipeline υ into the boiler.
