Die Gisela (benannt nach einer k.u.k. Kronprinzessin) fährt Sonderfahrten am Traunsee im österreichischen Salzkammergut und ist ein 52m langer und 180 t verdrängender Raddampfer mit oszillierender Zweizylinder Verbundmaschine. Der Dampf kommt mit 10 bar in den Hochdruckzylinder, leistet dort Arbeit und entspannt sich auf 3 bar. Dieser Abdampf wird dann im größeren Niederdruckzylinder verwendet, alles das spart Treibstoffkosten. Die Zylinderflächen verhalten sich umgekehrt wie die Dampfdrücke, also 3 : 10, damit dieselbe Kraft an der Kurbelwelle wirkt (Kraft = Druck * Fläche). Diese max. 172 PS starke Maschine ist ein schönes Beispiel tschechischer Maschinenbaukunst.
Oszillierende Maschinen, bei denen die Zylinder um eine Achse schwingen, waren um die Mitte des 19. Jahrhunderts Standard im Schiffsbau und wegen ihrer Zuverlässigkeit beim Personal beliebt. Die Kolbenstange braucht kein Kreuzkopfgelenk, der Kolben wírkt direkt auf die Kurbelwelle, die Dampfzufuhr und -abfuhr erfolgt über das Drehgelenk des Zylinders. Die Dampfsteuerung ist aber durch diese schwingende Bewegung schwierig und verlangt ein Gestänge mit ausgeklügelter Kinematik, das vom britischen Maschinenbauer John Penn um 1850 herum mit einer Bogenkulisse zur Übertragung der Bewegung vom Exzenter auf den mitschwingenden Dampfschieber perfektioniert wurde. Wie das funktioniert, sieht man in meinem Video 'Oscillating Steam Engine With Penn's Valve Gear'.
Die Besonderheit dieser Dampfmaschine ist die Umsteuerung von Vor- auf Rückwärtsfahrt mit Hilfe eines losen Exzenters. (Die elegantere Stephenson Steuerung verwendet statt dessen 2 fixe Exzenter). Hier kann sich der Exzenter, mit dem das Schieberventil gesteuert wird, um einen bestimmten Winkelbereich (ca. 120°) zwischen 2 Anschlägen auf der Kurbelwelle frei bewegen (siehe Video). Je nach Drehrichtung wird dann der Exzenter vom entsprechenden Anschlag mitgenommen. Zusätzlich kann zum Umsetzen die Verbindung zwischen Exzenterstange und Dampfschieber getrennt werden, um diesen Vorgang zu erleichtern (siehe Szene am Anfang des Videos).
Insgesamt wird das Schiff nur von 4 Personen (Kapitän, Maschinist (zugleich Heizer) und Matrose) bedient, eine Dame ist fürs Buffet zuständig. Heuer ist das Schiff im 140. Jahr unterwegs, glücklicherweise wurde sie durch einen Freundesverein vor der Verschrottung gerettet.
Mein spezieller Dank geht an Thomas Gschwandtner, den Engineer, der mir das, was mir nicht klar war, gut erklärt hat.
Die Gisela verkehrt leider nur an den Sonntagen im Juli und August und das auch nur bei Schönwetter. Insgesamt ist eine Fahrt mit der Gisela aber jede Anreise wert. Details über die Gisela und Fahrplan auf www.traunseeschifffahrt.at/
Leider kann man aus Platzgründen als Amateurfilmer nicht in den Maschinenraum, aber ich hab' trotzdem versucht, teilweise mit umgedrehter Kamera an einem in die Nähe der Maschine hinunter gehaltenen Einbeinstativ, das Beste daraus zu machen. Viel Vergnügen!
The Austrian steamship Gisela (the name of an Austrian princess) was built in 1871, the steam engine in 1870. She is the queen of Traunsee, a beautiful lake in the Austrian Salzkammergut. Her length is 52 metres (173 ft) and her displacement 180 tons.
The oscillating compound engine (high pressure 10 bars, low pressure 3 bars, 172 hp) was built in Praha - now the capital of the Czech Republic, the ship near Vienna. The engine's reverse valve gear is a very early one, working with sliding eccentrics and using Penn's sliding link. How that works, you can see in meinem Video 'Oscillating Steam Engine With Penn's Valve Gear'.
It's a hard job for the engineer, to turn the direction of rotation, not to compare with a Stephenson's valve gear. You can see all that with captions in this video.
The steamer is run by four hands: captain, engineer, who is also responsible for the oil fired boiler and one sailor. The fourth person is helping at the ship's bar.
There is one drawback: Only on Sundays in July and August and only at friendly weather conditions Gisela does a 2 ½ hour turn. For a time schedule please look at www.traunseeschifffahrt.at/ .
I can give best recommendations to this trip -- especially when you are interested in steam -- the engineer is an expert, who will answer any questions.
Enjoy the video and thanks for watching!

A lovely lady with a fantastic machine, and a good video. We have a similar steamer in Norway, her name is DS Skibladner and was built in 1854 - 1856. She is the world's oldest operating Wheel steamer in scheduled traffic, and goes with passengers in the summer. She is 165 feet long and 16.7 feet wide, she has a triple expansion machine of 606 horsepower. and the top speed is 14 knots at 44 rpm. She can seat 230 passengers and crew of 20.

Having Seen this boat many times, whilst visiting the area, a little of it's history should be mentioned. The boat sails on the Traunsee in Austria. In the mid 19th Century, it was caught in a storm in tne middle of the lake, and sank. It Lay on the bottom of the lake for circa 100 years before being raised and restored. In summer, it sails most Sundays with a Jazz band on board, and a leisure trip on it is a beautiful way to spend a nice sunny afternoon.

This engine has rocking cylinders. I had a toy steam engine with a rocking cylinder, and the rocking action itself effectively operated the "valves" such as they were. The toy engine could not be reversed.

really neat clip!, I got my little brain wrapped around the basic concepts, I will root around for more information on these type boat engines. query; in one of the small piston cavities, looks like a thick type of oil, is this used to absorb excess heat?

I am of an age whereupon my RCN apprenticeship involved operating a triple expansion engine with the subsequent palm-slap temperature testing of rotating big ends - if I had ever been seen doing that while holding a rag in the same hand - my engineroom CPO would have dented my skull with the Weir's pump spare piston rod.
