A hydraulic governor involves a rotary shaft carrying a valve body fixed thereto and primary and secondary valve elements slidably inserted into the valve body. A spring urges the primary valve element to produce a primary governor pressure rising from a predetermined speed. The primary governor pressure acts in a direction against the centrifugal force acting on the secondary valve element for producing a secondary governor pressure larger than the primary governor pressure at a varying rate. This governor may produce a stable governor pressure since the governor pressure is not affected by variations in line pressure.
