Description
Die Veränderung der. Expansion geschieht bei der vorliegenden Steuerung unmittelbar durch die Einwirkung des Regulators. Die Dampfkanäle, sowie die Kanten des cylindrischen Schiebers, sind unter 45 ° gegen die horizontale Schieber-Axe geneigt und der Schieber erhält eine doppelte Bewegung, nämlich eine gradlinige und eine drehende.The change in. Expansion happens immediately with the present control the action of the regulator. The steam channels, as well as the edges of the cylindrical Slide, are inclined under 45 ° against the horizontal slide axis and the slide receives a double movement, namely a straight line and a rotating one.
Die. constructive Ausführung ist aus der Zeichnung ersichtlich, und zwar stellt Fig. 1 eine Seiten-Ansicht, Fig. 2 einen Grundrifs mit theilweisem Horizontalschnitt der Steuerungstheile dar, während Fig. 3 einen Querschnitt durch den Schieberkasten nach A B zeigt.The. The constructive design is evident from the drawing, namely Fig. 1 shows a side view, Fig. 2 shows a basic outline with a partial horizontal section of the control parts, while Fig. 3 shows a cross section through the valve body to AB .
Der in dem Schieberkasten A sich bewegende Schieber B ist unbeweglich auf der Schieberstange C befestigt, welche ihrerseits am anderen Ende drehbar in einem Rahmen D sitzt. Dieser wird horizontal geführt und umfafst die Schwungradwelle; er ist mit zwei Frictionsrollen E ausgestattet, aufweicher der Daumen i^der Schwungradwelle G sitzt; die Dampfeintrittskanäle a a führen nach den beiden Enden des Cylinders.The slide B moving in the slide box A is fixed immovably on the slide rod C , which in turn is rotatably seated in a frame D at the other end. This is guided horizontally and includes the flywheel shaft; it is equipped with two friction rollers E on which the thumb sits on the flywheel shaft G; the steam inlet channels aa lead to the two ends of the cylinder.
Die Rückfläche des Schiebers ist gleichgestaltet der eigentlichen Schieberfläche und ist erstere durch eine Platte H abgedeckt, welche den Kanälen am Cylinder entsprechen und mit dieser mittelst kleiner Bohrungen communiciren.The rear surface of the slide is shaped like the actual slide surface and the former is covered by a plate H which corresponds to the channels on the cylinder and communicates with them by means of very small bores.
Es wird hierdurch eine allseitige vollständige Druckausgleichung und somit vollständige Entlastung des Schiebers hervorgebracht. Die Abnutzung des Schiebers wird unschädlich gemacht durch eine keilförmige Platte P, welche zwischen der Deckplatte H und dem Scbieberkastendeckel Q liegend eine selbsttätige Nachstellung dadurch bewirkt, dafs der Dampf auf die breitere Endfläche einen gröfseren Druck ausübt, als auf die schmale.This brings about complete pressure equalization on all sides and thus complete relief of the slide. The wear and tear of the slide is rendered harmless by a wedge-shaped plate P, which, lying between the cover plate H and the switch box lid Q, causes an automatic readjustment in that the steam exerts a greater pressure on the wider end surface than on the narrow one.
Die Drehung des Schiebers erfolgt mittelst des Hebels h, welcher durch eine Stange / und den Arm η mit der Schieberstange verbunden ist, derartig, dafs diese sich innerhalb des Auges n verschieben kann.The slide is rotated by means of the lever h, which is connected to the slide rod by a rod / and the arm η , in such a way that it can move within the eye n .
Der Hebel h wird durch die auf der Schwungradwelle sitzende, durch den Regulator axial verschiebbare Hülse e gehoben. Die Oeffnung der Dampfkanäle wird durch die Horizontalverschiebung des Schiebers eingeleitet und durch die Drehung ganz vollendet; passirt hierauf die Kante α b der Hülse die Frictionsrolle c des Hebels, so wird dieser durch sein eigenes Gewicht eventuell auch durch eine Feder nach unten bewegt; es dreht sich dadurch der Schieber in einer der vorigen entgegengesetzten Richtung, der Kanal wird geschlossen und so ist die Expansion erreicht. Je nach dem Stande des Regulators, welcher direct über der Schwungradwelle angebracht ■ ist und vermittelst eines Winkelhebels die Verstellung der Hülse bewirkt, wird die Expansion eine gröfsere oder kleinere sein, da die Kante α b der die Drehung des Schiebers vermittelnden Hülse schraubenförmig gestaltet ist, so dafs das Fallen des Hebels h entsprechend früher oder später eintritt.The lever h is lifted by the sleeve e seated on the flywheel shaft and axially displaceable by the regulator. The opening of the steam channels is initiated by the horizontal displacement of the slide and completely completed by the rotation; If the edge α b of the sleeve then passes the friction roller c of the lever, it is moved downwards by its own weight, possibly also by a spring; as a result, the slide rotates in a direction opposite to the previous one, the channel is closed and expansion is achieved. Depending on the position of the regulator, which is attached directly above the flywheel shaft and effects the adjustment of the sleeve by means of an angle lever, the expansion will be larger or smaller, since the edge α b of the sleeve that mediates the rotation of the slide is designed in a helical shape, so that the falling of the lever h occurs sooner or later.
Patent-Anspruch: Die selbstthätig durch den Regulator verstellbare Expansionssteuerung in ihrer durch Zeichnung und Beschreibung erklärten Zusammensetzung, insbesondere die Hervorbringung der Dampfvertheilung und Expansion durch zwei verschieden gerichtete Bewegungen· eines und desselben Schiebers.Patent claim: The expansion control that can be adjusted automatically by the regulator in their composition explained by drawing and description, in particular the production the steam distribution and expansion through two differently directed movements one and the same slide.
