Claims

[Scope of utility model registration request]

In the fuel injection pump auto-timer, which is installed between the engine and the fuel injection pump and transmits the power of the engine to the fuel injection pump and controls the fuel injection timing, the drive shaft to which power is transmitted from the engine and the transfer injection A pinion that is provided between the pump shafts that drives the pump and selectively engages with teeth formed on both shafts, a spider that supports the pinion via the pinion shaft, and a spider that supports the drive shaft and the pump shaft in common. A bearing device, a reference signal generator that generates a predetermined reference angle signal based on various operating conditions of the engine, a servo device that rotates the spider to control the phase difference between the drive shaft and the pump shaft, and the drive shaft. and a phase difference signal generator for detecting the phase difference generated between the pump shaft and the pump shaft, and a comparator for comparing each output of the reference signal generator and the phase difference signal generator, and the output of this comparator is sent to the servo device. An automatic timer for a fuel injection pump, wherein the servo device is controlled so that the output of the reference signal generator and the output of the phase difference signal generator coincide with each other.
