Vorrichtung an doppelcylindrigen, rotirenden Dampfmaschinen zur Steuerung, bezw. Umsteuerung derselben.Device on double-cylinder, rotating steam engines for control, respectively Reversal of the same.
Patentirt im Deutschen Reiche vom 6. Juli 1877 ab.Patented in the German Empire on July 6, 1877.
Diese Maschine besteht aus dem doppelten Cylinder e, dessen Bohrungen sich berühren, den gufseisernen Kolben f in Form gerade gedrehter Walzen mit den Stahlwellen g und den Stahlflügeln h; dieselben liegen excentrisch zur Bohrung der Cylinder und laufen fest gegen einander und bilden durch letzteres eine sichere Dichtung (ohne Ende) zwischen der Dampfeinströmung und Ausströmung.This machine consists of the double cylinder e, the bores of which touch, the cast iron piston f in the form of straight-turned rollers with the steel shafts g and the steel blades h; these are eccentric to the bore of the cylinder and run tightly against each other and through the latter form a secure seal (without end) between the steam inflow and outflow.
Ferner den Umsteuerungsschiebern i mit Stellmechanismus, dem Schiebergehäuse k mit dem Absperrventil υ und den Stopfbüchsen für die Abdampfrohre /, den Cylinderdeckeln m mit angeschraubtem Excenter η, Stopfbüchse und Lagerconsolen, dem Dampfrohr 0 mit Schrauben /, den Lagern q mit Keilvorrichtung u und dem Stirnräderpaar r. Furthermore, the reversing slide valve i with the adjusting mechanism, the slide valve housing k with the shut-off valve υ and the stuffing boxes for the exhaust pipes /, the cylinder lids m with screwed-on eccentrics η, stuffing box and bearing brackets, the steam pipe 0 with screws /, the bearings q with the wedge device u and the pair of spur gears r.
Der Dampf tritt, wie durch Stellung der Schieber auf Zeichnung angegeben, durch das Dampfrohr ο und das geöffnete Ventil ν in das untere Schiebergehäuse k, geht um die Schieber i herum durch die offenen drei mittleren Einströmungs-Kanäle in die beiden Cylinder und drückt gegen die Flügel h und dreht dadurch die Kolben in der angegebenen Pfeilrichtung herum. Bei den oberen, äufseren (nur zur Dampfausströmung dienenden) Kanälen angelangt, entweicht der Dampf, durch dieselben, sowie auch durch die drei mittleren Kanäle, sodann durch den Schieber i und das Dampfabgangs-Rohr /. Will man mit geringerer Füllung arbeiten, so stelle man die Schieber so, dafs nur der mittlere Kanal geöffnet bleibt und die bieden seitlichen Emströmungs-Kanäle ge-, schlossen sind. Die Dampfausströmungs-Kanäle sind in den Schiebern so weit gehalten, dafs diese Schieberstellung den freien Dampfaustritt nicht hindert.As indicated by the position of the slide on the drawing, the steam enters the lower slide housing k through the steam pipe ο and the open valve ν , goes around the slide i through the open three central inflow channels into the two cylinders and presses against the Wing h and thereby rotates the pistons in the direction of the arrow. Arrived at the upper, outer channels (only used for steam outflow), the steam escapes through them, as well as through the three middle channels, then through the slide i and the steam outlet pipe /. If one wishes to work with a smaller filling, then the slide valves are set so that only the central channel remains open and the two lateral inflow channels are closed. The steam outflow channels are kept so wide in the sliders that this slider position does not prevent the free escape of steam.
Werden die Schieber behufs Umsteuerung in Bewegung gesetzt, so legt sich der am Schieber befindliche Ansatz χ gegen den Zapfen des Ventilkegels υ und öffnet das Ventil. Da nun die Schieberbewegung eine einander entgegengesetzte ist, so wird das Ventil auf der anderen Seite geschlossen. Der Dampf wirkt jetzt auf dieselbe Weise wie vorhin und dreht die Kolben in entgegengesetzter Richtung herum. Die Ventile ν haben vorzüglich auch noch den Zweck, denjenigen Schieber, welcher beim Gange der Maschine für die Ausströmung gestellt ist, zu entlasten und das Ansammeln von Wasser im Schieberkasten zu verhindern. Die an die Cylinderdeckel angeschraubten Excenter sitzen centrisch mit der Cylinderbohrung und dienen dazu, die Flügel h beim Anlassen der Maschine gegen die Cylinderwandung zu halten. Beim Gange der Maschine kommen die Excenter weniger zur Geltung, da dann die Flügel durch die Centrifugalkraft nach aufsen geschleudert werden.If the slide is set in motion for the purpose of reversing, the attachment χ on the slide rests against the pin of the valve cone υ and opens the valve. Since the slide movement is now opposite to one another, the valve on the other side is closed. The steam now works in the same way as before, turning the pistons in the opposite direction. The valves ν also have the primary purpose of relieving that slide which is set for the outflow when the machine is in motion and to prevent water from collecting in the valve body. The eccentrics screwed onto the cylinder cover sit centrically with the cylinder bore and serve to hold the blades h against the cylinder wall when the machine is started. When the machine is in motion, the eccentrics are less effective because the centrifugal force then flings the wings outward.
Das Stirnräderpaar r dient dazu, die Kolben stets in gleichlaufender Bewegung zu halten und die Kraft beider zu vereinigen.The pair of spur gears r is used to keep the pistons always moving in the same direction and to combine the power of both.
Die auf Zeichnung dargestellte Maschine ist für ca. 10 Ps. Ihre Leistungsfähigkeit ist im Verhältnifs zu ihrem geringen Dampfverbrauch eine bedeutende.The machine shown in the drawing is for approx. 10 P s . Their efficiency is significant in relation to their low steam consumption.
Durch den geringen Raum, den die Maschine einnimmt, durch den schnellen Gang und die Möglichkeit der Bewegungsumkehrung würde sich die Maschine besonders gut zu Schiffsoder auch Förderungsmaschinen eignen. Because of the small space that the machine takes up, because of the high speed and the With the possibility of reversing the movement, the machine would be particularly suitable for ship or conveyor machines.
Hierzu I Blatt Zeichnungen.For this purpose I sheet drawings.
