What is hydraulic governor?

A hydraulic governor is a device used to regulate the speed of an engine or turbine by controlling the flow of hydraulic fluid based on the load conditions. It operates by adjusting the fuel supply or hydraulic input to maintain a constant speed despite variations in load. This ensures optimal performance and efficiency in systems such as hydroelectric plants or internal combustion engines. By responding to changes in speed, hydraulic governors help maintain stability and prevent overspeed conditions.
