Paddle Steamer Uri

Paddle Steamer Uri
1901

oldest operating vessel with a diagonal, compound steam engine, with disc valve gear

This is the oldest operating vessel with a diagonal, compound steam engine, with disc valve gear. Operating at a higher pressure than the oscillating-cylinder engines then used in lake steamers, this type of engine was more powerful and efficient, as well as smaller. The compound engine, built by Sulzer brothers of Winterthur, uses super-heated steam from the boilers in two stages-high and low pressure-before exhausting it into a condenser. The engine produces 650 horsepower, turning two paddle wheels.

Further information on the Uri is available in the Landmark Brochure

In September 2007, at 106 years old, Uri surpassed the 2 million kilometer mark. Swiss press reported the achievement (article in German).
