Description

Doppeltwirkende Kolbendampfmaschine mit Abdampfverwertung. Die Erfindung betrifft eine doppeltwirkende, mit Gegendruck arbeitende Kolbendampfmaschine, bei welcher die beiden an je eine besondere Abdampfleitung angeschlossenen Zylinderseiten mit verschiedenen Gegendrücken arbeiten. Die Regelung der an den einen Abdampfverbraucher oder an die Abdampfverbraucher abgegebenen Abdampfmengen ist bisher in der Weise bewerkstelligt worden, daß der der Maschine vom Geschwindigkeitsregler zugeteilte Dampf von einem weiteren Regler in entsprechender Weise auf die beiden Zylinderseiten verteilt worden ist. Diese bekannte Regelung hat den Nachteil, daß sie eine umständliche Einrichtung erfordert und eine oft sehr ungleiche Belastung der Zylinderseiten bedingt.Double-acting piston steam engine with exhaust steam recovery. The invention relates to a double-acting piston steam engine working with counter pressure which the two cylinder sides each connected to a special exhaust line work with different counter pressures. The regulation of the one exhaust steam consumer or the amount of exhaust vapor given off to the exhaust gas consumers is currently in the manner has been brought about that the speed assigned to the machine by the speed controller Steam from another regulator in the same way on the two cylinder sides has been distributed. This known scheme has the disadvantage that it is a cumbersome Requires establishment and often causes very uneven loading of the cylinder sides.

Mit der Erfindung wird bezweckt, die Abdampfverteilung mit besonders einfachen Mitteln zu regeln. Sie besteht darin, daß die beiden Abdampfräume unter sich durch ein Druckregelorgan derart verbunden sind, daß der von der Maschine im Überschuß gelieferte Abdampf höheren Drucks in die Abdampfleitung niedrigeren Drucks überströmt.The aim of the invention is to reduce the steam distribution with particular simple means to regulate. It consists in the fact that the two evaporation spaces under are connected by a pressure control member in such a way that the from the machine in Excess of higher pressure exhaust steam supplied into the lower pressure exhaust line overflows.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung schematisch dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown schematically.

a ist der Zylinder, b der Kolben einer doppeltwirkenden Dampfmaschine, c ist die an die linke Zylinderseite angeschlossene Abdampfleitung für den niedrig gespannten und d die an die rechte Zylinderseite angeschlossene Abdampfleitung für den höher gespannten Abdampf. e ist ein, die beiden Abdampfleitungen verbindendes selbsttätig in der Weise sich einstellendes Überströmventil, daß der von der rechten Zylinderseite abgegebene Überschuß über den Bedarf an höher gespanntem Abdampf in die linke Abdampfleitung überströmt. Die selbsttätige Wirkung des Ventils e wird mit Hilfe der Feder f erzielt, die in der Schließrichtung so auf das Ventil wirkt, daß sich dessen Durchflußquerschnitt mit zunehmendem Druck in d vergrößert und mit abnehmendem Druck verkleinert. Die Feder könnte auch so angeordnet sein, daß ihre Spannung z. B. durch ein Handrad verstellbar ist.a is the cylinder, b the piston of a double-acting steam engine, c is the exhaust line connected to the left side of the cylinder for the low tensioned and d the exhaust line connected to the right side of the cylinder for the higher tensioned exhaust steam. e is an overflow valve that connects the two exhaust lines and automatically adjusts itself in such a way that the excess discharged from the right side of the cylinder overflows into the left exhaust line beyond the need for higher pressure exhaust steam. The automatic action of the valve e is achieved with the aid of the spring f, which acts on the valve in the closing direction in such a way that its flow cross-section increases with increasing pressure in d and decreases with decreasing pressure. The spring could also be arranged so that its tension z. B. is adjustable by a handwheel.

Die Einstellung dieses Ventils kann mit Hilfe eines Druckreglers, z. B. eines an die rechte Abdampfleitung angeschlossenen Druckreglers, erfolgen. Wenn der Verbrauch an höher gespanntem Abdampf die Hälfte der von der Maschine abgegebenen Gesamtabdampfmenge übersteigt, so wird die Füllung der mit höherem Gegendruck arbeitenden Zylinderseite unter entsprechender Verkleinerung der Füllung der andern Zylinderseite von einem an sich bekannten, an die eine Abdampfleitung angeschlossenen und die Steuerung beeinflussenden Druckregler entsprechend dem Mehrbedarf an höher gespanntem Abdampf vergrößert.The setting of this valve can be done with the help of a pressure regulator, z. B. a pressure regulator connected to the right exhaust line. If the consumption of high-pressure exhaust steam is half of that given off by the machine If the total amount of vapor is exceeded, the filling becomes the one that works with a higher counterpressure Cylinder side with corresponding reduction of the filling of the other cylinder side of a known per se, connected to an exhaust line and the Control influencing pressure regulator according to the additional need for higher tensioned Exhaust steam increased.
