A Corliss steam engine – the valve gear is on the right of the cylinder block, on the left of the picture. A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the US engineer George Henry Corliss of Providence, Rhode Island.
George Henry Corliss (June 2, 1817 – February 21, 1888) was an American mechanical engineer and inventor, who developed the Corliss steam engine, which was a great improvement over any other stationary steam engine of its time. The Corliss engine is widely considered one of the more notable engineering achievements of the 19th century.
As time passed, owing to developments in technology and the decreasing popularity of the Corliss steam engine, Watts Campbell stopped producing steam engines. The electrification of industry and more efficient steam turbine generators rendered the Corliss steam engines obsolete. After the 1920s, the factory specialized in constructing and ...
The Corliss Engine displayed at the International Exhibition of Arts, Manufactures and Products of the Soil and Mine of 1876. The last major improvement to the steam engine was the Corliss engine. [6] Named after its inventor, George Henry Corliss, this stationary steam engine was introduced to the world in 1849.
1849 (): George Henry Corliss develops and markets the Corliss-type steam engine, a four-valve counterflow engine with separate steam admission and exhaust valves. Trip valve mechanisms provide sharp cutoff of steam during admission stroke. The governor is used to control the cut off instead of the throttle valve.
The Corliss engine had greatly improved speed control and better efficiency, making it suitable to all sorts of industrial applications, including spinning. Corliss used separate ports for steam supply and exhaust, which prevented the exhaust from cooling the passage used by the hot steam.
A steam engine fitted with rotary valves and having variable valve timing was invented by and named for an American Engineer, George Henry Corliss, in 1849. Engines fitted with Corliss valve gear offered the best thermal efficiency of any type of stationary steam engine until the refinement of the uniflow steam engine and steam turbine in the ...
