Bei dieser Expansionsvorrichtung sind die Expansionsschieberplatten e, welche in den Hauptschiebern h laufen, mit eingeschraubten durchbohrten Pfropfen f versehen. Man kann daher durch Einsetzen von Pfropfen mit gröfserer oder kleinerer Bohrung diese Schieber je nach Bedürfnifs mehr oder weniger entlasten, so dafs dieselben leicht vom Regulator beherrscht werden können, dicht schliefsen und sich nur unmerklich abnützen.In this expansion device, the expansion slide plates e, which run in the main slide h , are provided with screwed-in pierced plugs f. Therefore, by inserting plugs with larger or smaller bores, these slides can be more or less relieved as required, so that they can easily be controlled by the regulator, close tightly and wear only imperceptibly.
Behufs Bewegung dieser Expansionsplatten und deren gegenseitiger Verstellung durch den Regulator ist ein Rahmen R eingeschaltet. A frame R is switched on for the purpose of moving these expansion plates and their mutual adjustment by the regulator.
Derselbe schwingt um seine Axe α, und auf der am unteren Ende befindlichen Axe b sitzt lose eine mitschwingende Scheere s. Die oberen Schenkel dieser Scheere, deren Längen gleich sind der Entfernung des Axenmittels α vom Axenmittel b, stehen mit dem Regulator in unlöslicher Verbindung, während die unteren Schenkel mit den Expansionsschieberstangen verbunden sind. Ein Steigen oder Fallen des Regulators wird daher die Expansionsplatten von einander entfernen oder einander nähern, mithin eine gröfsere oder geringere Expansion bewerkstelligen.. Rahmen und Scheere werden durch ein gewöhnliches Excenter hin- und herbewegt. Bei dieser Bewegung sucht der Bewegungswiderstand der einen Platte den Regulator herunterzuziehen, derjenige der anderen Platte denselben zu heben; es wird also bei zweckmäfsiger Plattenentlastung nur eine geringe Rückwirkung auf den Regulator stattfinden und dieser bei nur mäfsigen Dimensionen seine Arbeit rasch und' gut verrichten.The same swinging around its axis α, and b on the lower-end Ax is loose a resonating scissors s. The upper leg of this pair of scissors whose lengths are equal to the distance of the Axenmittels α from Axenmittel b, are provided with the regulator in insoluble compound while the lower legs are connected to the expansion valve rods. A rise or fall of the regulator will therefore move the expansion plates away from one another or bring them closer to one another, and consequently bring about greater or lesser expansion. The frame and scissors are moved to and fro by a common eccentric. During this movement, the resistance to movement of one plate tries to pull down the regulator, that of the other plate tries to raise it; If the plate is appropriately relieved of pressure, there will be only a slight reaction on the regulator and, with only moderate dimensions, it will do its work quickly and well.
Der Umstand, dafs der Regulator in fortwährender unlöslicher Verbindung mit den Expansionsplatten bleibt, gestattet die Anwendung dieser Expansionsvorrichtung auch bei sehr schnell gehenden Maschinen.The fact that the regulator is in permanent, insoluble connection with the expansion plates remains, allows the use of this expansion device even with very fast moving machines.
Durch Anwendung der Scheere kommt das Schiebermittel unter das Cylindermittel zu liegen und das Condensationswasser kann aus dem Cylinder durch die Dampfwege abfliefsen.By using the scissors, the slide means come to rest under the cylinder means and the condensation water can flow out of the cylinder through the steam paths.
Um nicht zu breite Schieber oder zu grofse Schieberwege zu erhalten, sind in beiliegender Zeichnung Dampfkanäle sowohl als Hauptschieber und Expansionsplatten doppelt angenommen.In order not to obtain too wide sliders or too large slider paths, are enclosed Drawing steam channels assumed doubly as both main valve and expansion plates.
Soll der abgehende Dampf des Cylinders, bevor er nach dem Condensator geht, durch einen hinter demselben liegenden gröfseren Cylinder gehen, so können die einen gröfseren Hub beanspruchenden Expansionsplatten dieses zweiten Cylinders vom punktirten Zapfen ζ aus bewegt werden, der Hauptschieber vom punktirten Zapfen χ aus, ohne dafs es nöthig wäre, ein . weiteres Excentgt aufser den zwei vorhandenen anzuwenden, ^p»·If the outgoing steam of the cylinder, before it goes to the condenser, is to pass through a larger cylinder located behind it, the expansion plates of this second cylinder, which require a larger stroke, can be moved from the punctured pin ζ , the main slide from the punctured pin χ , without the need for a. to apply another excuse in addition to the two existing ones, ^ p »·
