Laval, Carl Gustaf Patrik de

born May 9, 1845, Blasenborg, Swed.
died Feb. 2, 1913, Stockholm

Swedish scientist, engineer, and inventor.

Laval built his first impulse steam turbine in 1882. Further advances followed, including a reversible turbine for marine use. A Laval reaction turbine attained a speed of 42,000 revolutions per minute. By 1896 he was operating a complete power plant using an initial steam pressure of 3,400 lbs per sq in. He invented and developed the divergent nozzle to deliver steam to the turbine blades. His flexible shaft and double-helical gear formed the foundation for most subsequent steam turbine development.

▪ Swedish scientist and engineer
born May 9, 1845, Blasenborg, Swed.
died Feb. 2, 1913, Stockholm

      Swedish scientist, engineer, and inventor who pioneered in the development of high-speed turbines (turbine).

      After 1872 he was an engineer with the Klosters-Bruck Steel Works. In 1878 he invented the centrifugal cream separator, and later he applied the principle of rotation to the manufacture of glass bottles.

      Laval built his first impulse steam turbine in 1882. Further advances followed, and in 1893 he built and operated a reversible turbine for marine use. A Laval reaction turbine (patented in 1883) attained a speed of 42,000 revolutions per minute. He continued improving his turbine until by 1896 he was operating a complete power plant using an initial steam pressure of 3,400 pounds per square inch. He invented and developed the divergent nozzle used to deliver steam to the turbine blades. His flexible shaft, used to eliminate wobbling, which can be dangerous at high speeds, and his special double-helical gear formed the foundation for most steam-turbine development that followed.
