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. Corliss assumed the original invention from Frederick Ellsworth Sickels (1819- 1895), who held the patent (1829) in ...
William Wright was an American engineer who contributed to the development of the Corliss steam engine in the mid 19th century. [1] [2]Wright also developed several innovative improvements in steam engine design such as the automatic shutoff steam engine which employed a governor to limit the engine's speed.
The drive shaft whose speed is being sensed is top right Porter governor on a Corliss steam engine. The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid ...
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
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.
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 success to come with stationary steam engines was in no small part based on the experiences with the short-lived railway locomotive production: the locomotives had boilers rated for 50 pounds per square inch (3.4 bar), compared to the normal stationary engine boiler rating at that time of 5 or 10 psi (0.34 or 0.69 bar).

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 ...
