Description

Druckluftmaschine. Es ist häufig erforderlich, das zum Betrieb von Druckluftmotoren bestimmte Druckmittel höher zu verdichten, als es im Motor verwendet wird. Das in einem Vorratsbehälter aufgespeicherte, hochgespannte Druckmittel wird in solchem Falle in einem Druckminderventil auf den gewünschten Arbeitsdruck von niedrigerer Spannung gebracht, wodurch jedoch ein erheblicher Teil der in dem hochgespannten Druckmittel enthaltenen Energie nutzlos verloren geht. Es ist schon vorgeschlagen worden, diesen Energieverlust dadurch zu verringern, daß das expandierende Druckmittel Luft oder Gas von niedrigerer Spannung in einem Inj ektor ansaugt und auf den gewünschten Arbeitsdruck verdichtet.Compressed air machine. It is often necessary to operate the Air motors compress certain pressure medium higher than it used in the engine will. The high-tension pressure medium stored in a storage container is in such a case in a pressure reducing valve to the desired working pressure of brought lower tension, which, however, a significant part of the in the high tension Energy contained in pressure medium is uselessly lost. It's already suggested been to reduce this energy loss in that the expanding pressure medium Air or gas of lower tension is sucked into an injector and at the desired point Working pressure compressed.

Die Anwendung eines solchen Inj ektors bei unter Tage arbeitenden Druckluftmotoren ist jedoch im allgemeinen deswegen nicht ohne weiteres möglich, weil durch die von außen angesaugte Grubenluft viel Schmutz in die Zylinder des Motors kommt, der einen großen Verschleiß zur Folge hat.The use of such an injector for those working underground In general, however, air motors are not easily possible because of this, because the pit air sucked in from the outside causes a lot of dirt to get into the cylinders of the Motor comes, which has a great deal of wear and tear.

Die vorliegende Erfindung vermeidet diesen Nachteil und ermöglicht die Anwendung eines Injektors dadurch, daß das im Motor bereits wirksam gewesene Druckmittel wieder angesaugt und nochmals verdichtet wird, so daß also dieser Teil des Druckmittels einen Kreislauf durchmacht.The present invention avoids this disadvantage and enables the use of an injector in that what has already been effective in the engine Pressure medium is sucked in again and compressed again, so that this part of the pressure medium goes through a cycle.

Da andererseits bei unter Tage arbeitenden, mehrstufigen Motoren das aus der Niederdruckstufe austretende Druckmittel dazu verwendet wird, die warme Grubenluft durch zwischen die einzelnen Stufen des Motors eingeschaltete Zwischenerwärmer hindurchzusaugen, so ist es vorteilhaft, einen Teil des aus der Hochdruck-oder auch einer Zwischenstufe austretenden Druckmittels im Inj ektor anzusaugen und wieder zu verdichten. Hierbei ergibt sich noch als besonderer Vorteil ein besserer Wirkungsgrad des Injektors, da in diesem Falle ein kleineres Verdichtungsverhältnis zu überwinden ist.On the other hand, with multi-stage engines working underground that from the low pressure stage exiting pressure medium is used to the warm Pit air through intermediate heaters connected between the individual stages of the engine to suck through it, it is advantageous to take some of the high pressure or also an intermediate stage to suck in exiting pressure medium in the injector and again to condense. A particular advantage here is a better degree of efficiency of the injector, since in this case a smaller compression ratio has to be overcome is.

Die Vorrichtung kann auch sinngemäß bei anderen unter oder über Tage arbeitenden Motoren sowie auch für Gase und Dämpfe Anwendung- finden.The device can also be used analogously for others underground or above ground working engines as well as for gases and vapors.

PATENT CLAIMS: i. Engine driven by compressed air, mainly for compressed air locomotives, the high-tensioned power medium of which expands without mechanical work to the working pressure suitable for the engine and thereby sucks in air of lower tension in an injector and compresses it to the working pressure, characterized in that the air sucked into the injector is completely or partially taken from the fuel that has already been effective in the engine, so that this part of the fuel goes through a cycle. Multi-stage engine according to Claim i, characterized in that the air sucked into the injector is taken from the high-pressure stage or from an intermediate stage of the engine.
