Claims

[Scope of utility model registration request]

a load shear break signal transmitter that becomes activated when the load on the prime mover is interrupted; an auxiliary relay that is energized when the load sheath break signal transmitter becomes activated;
Means for limiting fuel supply to the prime mover by operating a prime mover stop device when the auxiliary relay is energized; a pressure detection switch that outputs a signal according to the magnitude of the
Based on the output signal of the pressure switch, there is a timer that deenergizes the auxiliary relay at a set time when a predetermined period of time has elapsed since the load was cut off, and when the auxiliary relay is deenergized by this timer, the auxiliary relay becomes inactive and the An over-speed prevention device for a prime mover, comprising means for deactivating a prime mover stop device and supplying fuel corresponding to a no-load rated rotation.
