Um die Arbeitsleistung expandirender Druckluft zu vergröfsern und störende Abkühlung (also das Einfrieren der Maschine durch Vereisen der Auslafsöffnung) zu verhindern, leitet man nach einem bekannten Verfahren die Luft vor Eintritt in den Arbeitscylinder durch einen Vorwärmofen oder (nach Mekarski's System) durch einen Behälter mit heifsem Wasser, wobei dieses in Dunstform mitgerissen wird und seinen Wärmevorrath bei der Arbeitsleistung mittheilt.In order to increase the work capacity of expanding compressed air and disruptive cooling (i.e. to prevent the machine from freezing by icing over the outlet opening) according to a known method, the air before entering the working cylinder through a Preheating furnace or (according to Mekarski's system) by a container with hot water, whereby this is carried away in the form of a vapor and its supply of heat during work notifies.
Nach einem anderen Verfahren erfolgt während des Kolbenvorganges die Einführung gespannter Luft oder anderer indifferenter Gase und dann die Einführung eines zündfähigen Gemenges, das während des Einströmens allmälig verbrennt.Another method is to introduce tauts during the piston process Air or other inert gases and then the introduction of an ignitable mixture, which gradually flows in as it flows in burns.
Auch erfolgt wohl die Einführung von Druckluft und kurz nach seiner Entzündung die Einführung eines Gemisches in eine Heizkammer, aus welcher dann die so erhitzte Luft mit den Verbrennungsgasen in den Cylinder gelangt.Compressed air is also introduced and shortly after it has been ignited a mixture into a heating chamber, from which the heated air is then mixed with the Combustion gases get into the cylinder.
Der Uebelstand jener Verfahren besteht in einem unnöthig grofsen Luft- und Brennstoffverbrauch und erheblichen Wärmeverlusten.The disadvantage of these processes consists in an unnecessarily large consumption of air and fuel and significant heat losses.
Um diesen Uebelstand zu vermeiden, wird nach vorliegender Einrichtung die Druckluft im Innern des Cylinders also direct an der Verwendungsstelle durch einen oder mehrere von aufsen glühend gehaltene' Körper andauernd erwärmt und bei grofser Füllung und hohem Arbeitsbedarf auch noch durch eine oder mehrere im Cylinderinnern entzündbare Heizflammen erhitzt.In order to avoid this inconvenience, the compressed air is used according to the present device in the interior of the cylinder, therefore, directly at the point of use by one or more bodies kept glowing on the outside are constantly warmed and with a large filling and high work demand also due to one or more inflammable ones inside the cylinder Heated heating flames.
Beiliegende Zeichnung zeigt als Beispiel eine derartige doppeltwirkende Druckluftmaschine mit Schiebersteuerung unter Verwendung nur je eines glühend gehaltenen Körpers und einer Heizflamme für jede Kolbenseite.The accompanying drawing shows such a double-acting compressed air machine as an example with slide control using only one glowing body and one Heating flame for each side of the bulb.
.Die durch den Schieber α gesteuerte Druckluft erwärmt sich bei ihrem Austritt aus den Cylinderkanälen b in mäfsigem Grade an dem durch den Brenner c von aufsen stets glühend erhaltenen Körper d, der durch einen Stutzen des Deckels in das Cylinderinnere eintritt.The compressed air controlled by the slide α heats up when it exits the cylinder ducts b to a moderate degree on the body d, which is always glowing from the outside through the burner c, and which enters the inside of the cylinder through a socket in the cover.
Um die Druckluft während des Arbeitshubes bei beliebiger Kolbenstellung anfangend und aufhörend schnell beliebig hoch erhitzen zu können und unter möglichster Vermeidung von Verlusten die Wärme durch die Expansionskühlung sogleich in Arbeit umzuwandeln, tritt beim Oeffnen des Ventils e ein Strahl comprimirten Gemisches aus Brennstoff und Luft in den Cylinder, das sofort an der glühenden Fläche des glühenden Körpers d zu einer Heizflamme entzündet wird, welche die Natur und Eigenschaften einer sogenannten Bunsenflamme besitzt. Die Flamme strahlt, weil nicht leuchtend, sehr wenig Wärme durch den Luftinhalt des Cylinders hindurch an die Wände und brennt ohne jede Rufsbildung bei hoher Temperatur.In order to be able to quickly and quickly heat the compressed air as high as desired during the working stroke with any piston position and to convert the heat into work immediately by avoiding losses as much as possible, when valve e is opened, a jet of compressed mixture of fuel and air enters the Cylinder, which is ignited immediately on the glowing surface of the glowing body d to form a heating flame, which has the nature and properties of a so-called Bunsen flame. The flame, because it is not luminous, radiates very little heat through the air in the cylinder to the walls and burns at high temperature without any call formation.
Das entzündbare, aber nicht explosible Gemisch kommt dadurch zu Stande, dafs beimThe flammable, but not explosive, mixture comes about when the
Heben der Ventilspindel/ durch die Oeffnungg-Brennstoff und durch die Oeffnung /; Luft eintreten, die sich wie bei einem Bunsenbrenner vor dem Verbrennen in einem Mischraum innig mengen.Lifting the valve stem / through the fuel opening and through the opening /; Air in, which, like a Bunsen burner, are intimately prepared in a mixing room before burning amounts.
Diese Druckluftmaschine arbeitet also je nach Kraftbedarf nur mit der im Innern des Cylinders hervorgerufenen massigen Lufterwärmung an den glühenden Körpern d. oder auch (bei grofser Füllung und hohem Arbeitsbedarf) mit Lufterhitzung, hervorgerufen durch eine oder mehrere im Cylinderinnern entzündbare Heizflammen. Depending on the power requirement, this compressed air machine only works with the massive air heating on the glowing bodies inside the cylinder d . or (in the case of a large filling and high work requirements) with air heating, caused by one or more heating flames that can be ignited inside the cylinder.
Nach einer angestrengten Arbeitsperiode mit starker Wirkung der Heizflammen, bei welcher der Cylinder ziemlich heifs geworden sein mag, kühlt z. B. die bei geringerer Arbeitsleistung der Maschine ohne Heizflamme expandirende Druckluft die arbeitenden Organe wieder ab. Man kann also, sei es in längeren Zwischenräumen, sei es bei jedem Arbeitshub, die Expansionskühlung und die Heizwirkungen derart regeln, dafs die Druckmaschine weder vereist noch eines Kühlmantels bedarf,s um dauernd betriebsfähig zu bleiben.After a strenuous period of work with a strong effect of the heating flames, during which the cylinder may have become quite hot, z. B. the expanding compressed air without heating flame when the machine is less efficient, the working organs from again. One can therefore, be it at long intervals, it is regulated at each stroke, the expansion cooling and heating effects such, that the press does not iced still requires a cooling jacket to remain s to permanently inoperable.
Die andauernde Lufterwärmung im Cylinderinnern während der Arbeitsleistung verhindert nach Möglichkeit Wärmeverluste und setzt den Bedarf der Maschine an Druckluft auf ein Mind'estmafs herab.The constant heating of the air inside the cylinder during work is prevented If possible, heat losses and uses the machine's need for compressed air Mind'estmafs.
