The invention discloses a propeller speed regulator which comprises an upper shell assembly, a lower shell assembly, a bottom plate, an oil filter assembly, a speed selecting mechanism, a power turbine adjusting assembly, a gear pump, a pressure regulating and beta valve assembly and a reset handle assembly. Engine incoming oil is connected with a low-pressure oil groove in a bottom plate throughan oil filter assembly, and a gear pump outlet is divided into two paths which are connected with a high-pressure oil inlet of a beta valve assembly and a high-pressure oil cavity of a safety valve assembly respectively. A low-pressure oil cavity of the safety valve assembly is connected with a low-pressure oil groove; a high-pressure oil outlet of the beta valve assembly is connected with a high-pressure oil inlet of the speed selecting mechanism, and a high-pressure oil outlet of the speed selecting mechanism is connected with a propeller oil cavity; an oil return cavity of the beta valve assembly is connected with an oil groove II of the speed selecting mechanism; an oil return port of the speed selecting mechanism is connected with an oil return groove of the engine. The speed governorhas the advantages that the speed can be selected, feathering can be controlled, reverse propeller and balance rotating speed can be adjusted and controlled, the propeller using the speed governor ishigh in working efficiency, a large amount of fuel oil is saved, and working safety and reliability are high.
