KLASSE 14: Dampfmaschinen.CLASS 14: Steam Engines.
Diese Steuerung besteht aus dem eigentlichen Dampfcylinder α mit keilförmigen Ansatzflächen und den beiden Führungsbalken b bl. Die letzteren sind hohl; b enthält die Schlitze zur Dampfeinströmung, b1 diejenigen zur Dampfausströmung. Die Anordnung der Dampfkanäle ist eine solche, dafs sich immer die entgegengesetzten Schlitze des Cylinders und der Gleitbalken decken. Die Ausströmung des Dampfes geschieht an der tiefsten Stelle, so dafs sich nie Dampfwasser im Cylinder sammeln kann.This control consists of the actual steam cylinder α with wedge-shaped attachment surfaces and the two guide bars bb l . The latter are hollow; b contains the slots for steam inflow, b 1 those for steam outflow. The arrangement of the steam channels is such that the opposing slots of the cylinder and the slide bars always coincide. The outflow of steam occurs at the lowest point, so that steam water can never collect in the cylinder.
Die nutzbare innere Länge des Cylinders ist nun um einige Centimeter geringer, als dem Kolbenhub entsprechen würde, so dafs bei einer ganzen Kurbelbewegung der Kolben den Cylinder selbst ein kurzes Stück mitschleift, was dann die Umstellung des Dampfeintrittes bezw. Dampfaustrittes zur Folge hat. Um hierbei einen plötzlichen Stofs zu vermeiden, ist die Anordnung getroffen, dafs der Kolben zuerst den Dampfaustritt absperrt und dann auf ein Dampf kissen drückt, welches durch das Arbeitsvermögen des Schwungrades federartig zusammengeprefst wird und dann eine bedeutend höhere Spannung besitzt, als hinter dem Kolben herrscht. Ist der Druck in dem Raum vor dem Kolben genügend gestiegen, so wird der Cylinder in der Richtung der Kolbenbewegung sich verschieben. Hierbei werden der Dampfeintritt c und der Dampfaustritt i geschlossen und die Kanäle c1 und z1 geöffnet, worauf sich der gleiche Vorgang auf der entgegengesetzten Seite wiederholt. Damit der Cylinder nicht über die ihm gestattete Grenze sich verschiebe, wird ihm hinten und vorn ein elastischer Anschlag gegeben, welcher ihn am Weiterrutschen hindert. Derselbe kann in beliebiger Weise ausgeführt werden.The usable inner length of the cylinder is now a few centimeters less than would correspond to the piston stroke, so that with a whole crank movement the piston dragged the cylinder itself along a short distance. Has the consequence that steam escapes. In order to avoid a sudden explosion, the arrangement is that the piston first shuts off the steam outlet and then presses on a steam cushion, which is compressed like a spring by the working capacity of the flywheel and then has a significantly higher tension than that behind the piston . If the pressure in the space in front of the piston has risen sufficiently, the cylinder will shift in the direction of the piston movement. Here, the steam inlet c and the steam outlet i are closed and the channels c 1 and z 1 are opened, whereupon the same process is repeated on the opposite side. So that the cylinder does not move beyond the limit allowed for it, an elastic stop is given to it at the back and front, which prevents it from sliding further. The same can be done in any way.
Diese Dampfmaschine zeichnet sich hiernach aus: durch den Wegfall jedes speciellen Steuerungsmechanismus, durch die Umschaltung des Cylinders infolge erhöhten Dampfdruckes auf der einen Seite des Kolbens, durch die keilförmige Einlagerung in zwei Gleitbacken, welche zugleich die Dampf-Zu- und -Ableitung bilden, und durch die keilförmige Abdichtung der Dampfkanäle infolge des eigenen Gewichtes des Cylinders.This steam engine is characterized by the fact that there is no special control mechanism, by switching the cylinder as a result of increased vapor pressure on one side of the piston, by the wedge-shaped Storage in two sliding jaws, which at the same time form the steam inlet and outlet, and by the wedge-shaped sealing of the steam channels due to its own weight of the cylinder.
