Claims

[Scope of utility model registration request]

A pump linked to the output shaft of the engine, an orifice installed in the discharge flow path of the pump, and a piston that responds to the oil pressure generated upstream of the orifice and reduces the amount of fuel injection as the oil pressure increases. and an elastic means for biasing the piston in a direction opposing the hydraulic pressure, wherein the elastic means is a first elastic member that is initially loaded via the piston in a direction opposite to the opposing direction. A hydraulic governor comprising at least a body and a second elastic body that is provided in parallel with the first elastic body and is deformed when the piston is displaced from an initial position by a set value or more.
