A Governor Spring is used in small engines to control the engine's speed by regulating the amount of fuel that enters the engine. The governor spring is connected to the governor arm and the throttle linkage and it pulls on the governor arm to control the engine speed. Governor springs are typically made from steel or other high-strength materials that can withstand the stresses of engine operation.Attributes:• Provides very close regulation and pre-compression can be adjusted to give the required speed• Manufactured precisely to exact dimensions and tolerances to give improved durabilityApplications:A Governor Spring is used to control the actuator return which helps to vary the amount of fuel that enters the engine.
