tweeplankregelaar
The tweeplankregelaar, also known as a two-plank regulator or two-plank governor, is a mechanical device used to control the speed of steam engines by regulating the supply of steam to the engine cylinders. It was developed in the early 19th century as an improvement over earlier governor designs, such as those by James Watt.
The tweeplankregelaar consists of two parallel, rotating arms (or "planks") connected by a central spindle. These
The design relies on the balance between centrifugal force and gravity. When the engine speeds up, the
The tweeplankregelaar was widely used in early steam locomotives and stationary engines due to its simplicity
