PATENTSCHRIFTPATENT LETTERING

Patentirt im Deutschen Reiche vom 24. September 1898 afc.Patented in the German Empire on September 24, 1898 afc.

Der Gegenstand der Erfindung betrifft eine Verbesserung der in der Patentschrift Nr. 83211 dargestellten und beschriebenen geschlossenen Heifsluftmaschine.The subject matter of the invention relates to an improvement on that disclosed in Patent Specification No. 83211 illustrated and described closed hot air machine.

Diese Maschine unterscheidet sich von der Maschine der Patentschrift Nr. 83211 lediglich durch eine besondere Form der Verdrängerkolben, sowie durch die Art und Weise, in welcher die Führung der Gase nach bezw. von dem Feuertopf oder Kühlcylinder erfolgt.This machine differs from the machine of patent specification no. 83211 only by a special shape of the displacement piston, as well as by the way in which the gases are guided respectively from the fire pot or cooling cylinder.

Um nämlich eine schnelle Erhitzung oder Abkühlung des Arbeitsgases zu erzielen, wird anstatt der vielen konischen Röhren, aus welchen der Verdränger der Maschine der Patentschrift Nr. 83211 zusammengesetzt ist, ein glockenförmiger Verdränger verwendet, welcher beim Vorwärtshub das Gas in seinen mittleren, gewissem:afsen einen .Behälter bildenden Raum einsaugt und beim Rückwärtshube wieder ausstöfst; zwischen dem Verdränger einerseits und dem Feuertopf bezw. dem Kühlbehälter andererseits werden hierbei zwei zu einander concentrische Ringkanäle gebildet, durch welche das Gas fliefsen mufs. Zum Unterschiede von anderen ebenfalls mit einem glockenförmigen Verdränger arbeitenden Maschinen, vergl. z. B. die Patentschrift Nr. 7201, ist die Anordnung so getroffen, dafs das Arbeitsgas nicht nur beim Ansaugen durch den Verdränger, sondern auch beim Ausstofsen die beiden concentrischen Ringkanäle durchströmt, so dafs es also beim Ausstofsen nochmals mit den Wandungen des Feuertopfes bezw. des Kühlbehälters in innige Berührung kommt. Hierin ist das Wesen der Erfindung zu erblicken.In order to achieve rapid heating or cooling of the working gas, is instead of the many conical tubes that make up the displacer of the patent's machine No. 83211 is composed, uses a bell-shaped displacer, which on the forward stroke, the gas enters its central space, in a certain sense: a sucked in and pushed out again on the reverse stroke; between the displacer on the one hand and the fire pot respectively. the cooling container on the other hand are here two to each other concentric ring channels are formed through which the gas must flow. The difference between other machines also working with a bell-shaped displacer, cf. B. the patent specification No. 7201, the arrangement is made so that the working gas is not only when sucking in by the displacer, but also when it comes to the outside, the two concentric ones Flows through ring channels, so that it is again with the walls of the outside Fire pot resp. of the cooling container comes into intimate contact. Herein is the essence of Invention to behold.

Die Maschine ist in den Zeichnungen dargestellt. Fig. ι zeigt die Verdrängerkolben in derjenigen Lage, in welcher sie den heifsen bezw. den kalten Raum vollständig ausfüllen. Die Maschine ist dabei als doppelt wirkende Maschine gedacht. Der zweite Behälter ist in punktirten Linien angedeutet. Fig. 2 zeigt diejenige Lage der Verdrängerkolben, bei welcher der eine Kolben sich gänzlich aus dem Heifsluftraum herausbewegt hat, also den Augenblick der beginnenden Spannungssteigerung, wo der Kolben im Begriff ist, seinen Arbeitshub zu beginnen. Fig. 3 zeigt den Kaltluftraum in Wirksamkeit. Fig. 4 endlich veranschaulicht ein Arbeitsdiagramm des Kolbens.The machine is shown in the drawings. Fig. Ι shows the displacement piston in the situation in which they are hot or. completely fill the cold room. The machine is intended as a double-acting machine. The second container is in indicated by dotted lines. Fig. 2 shows that position of the displacement piston in which the one piston has moved completely out of the hot air space, that is, the moment the beginning of the increase in tension, where the piston is about to begin its working stroke. Fig. 3 shows the cold air space in effectiveness. Figure 4 finally illustrates a working diagram of the piston.

Die beiden Verdrängerkolben AA¹ werden vermittelst Kurbelantriebs durch Kolbenstangen & und b^l abwechselnd auf- und abbewegt und bewirken auf diese Weise ein Hin- und Herfliefsen der Arbeitsgase in dem dieselben aufnehmenden Behälter. Die in die Gasbehälter hineinragenden Theile der glockenförmigen Verdrängerkolben, d. h. die eigentlichen Verdränger, sind mit cc¹ bezeichnet, die entsprechenden Theile der Gasbehälter tragen die Bezeichnung a a¹. The two displacement pistons AA ¹ are alternately moved up and down by means of a crank drive by piston rods & and b ^l and in this way cause the working gases to flow back and forth in the container that holds them. The parts of the bell-shaped displacement pistons protruding into the gas containers, ie the actual displacers, are denoted by cc ¹ , the corresponding parts of the gas containers are denoted by aa ¹ .

Den Hohlräumen in dem glockenförmigen Verdrängerkolben entsprechen glockenförmige Einbaue B in dem erhitzten oder abgekühlten Theile des Gasbehälters. Die Erhitzung des unteren Theiles des Gasbehälters erfolgt durch einen beliebigen Herd F, während der obere Theil des Gasbehälters von einem Kühlraum G umschlossen ist.The cavities in the bell-shaped displacement piston correspond to bell-shaped fittings B in the heated or cooled part of the gas container. The lower part of the gas container is heated by any stove F, while the upper part of the gas container is enclosed by a cooling space G.

Der centrale Theil C des Gasbehälters ist mit dem Cylinder D, in welchem der Kolben P The central part C of the gas container is connected to the cylinder D, in which the piston P.

works, connected by a channel E. At its other end, the cylinder D is connected to a second gas container, in which displacement pistons A * A ^s work, through a channel E ¹ .

The machine works as follows:

Is transferred from the in Figure ι. Illustrated position of the displacer A rapidly into the position shown in Fig. 2 position, the gas container and the inner cavity of the displacement A is created between the bell B is a gasverdünnter space which an energetic subsequent flow in the central Gas masses located in the gas chamber C , especially since they are forced to avoid the displacement piston entering the central gas chamber.

Accordingly, there is a vigorous gas flow between the walls of the displacement piston and the gas container, which form two concentric annular channels, towards the cavity bounded above and below by the flat walls T and T ^{1 of} the displacement piston and the bell-shaped installation of the gas container. Already on the way to this cavity, since the gas masses move in a thin layer between the walls of the displacement piston and the gas container, the gases are heated considerably by the heated walls of the gas container. This heating is increased considerably during the time in which the displacement piston is in the position shown in FIG. The consequence of this is a strong increase in the gas tension, through the influence of which the piston P is advanced.

Simultaneously with the advance of the piston P there is a return movement of the displacement piston A , which is followed by an advance of the displacement piston A ¹ and the entry of the gases into the cooling chamber. When entering the cooling chamber, the gases are forced by the bell-shaped edge of the displacement piston A ¹ to flow in a thin layer along the cooled walls of the gas container, so that a very energetic cooling takes place and a harmful increase in pressure when the piston P moves back the position shown in Fig. 3 in the one shown in Fig. 1 and 2 is avoided. _N

The design of the displacer and. The way in which the working gas is conducted can also be used in machines other than those described in patent specification no If the rapid and strong heating or cooling takes place, while in other machines, in which the working piston and displacer work in a common space, the gases coming from the fire pot cannot convert their heat into work to a corresponding extent because they are prematurely cooled by the cold room will. -} '
