Claims

[Claims for Utility Model Registration] A cylinder, a timer piston fitted into the cylinder, a pressure oil chamber and a low pressure chamber defined by the timer piston, and a servo valve formed in the axial direction of the timer piston. an insertion hole, a servo valve fitted into the servo valve insertion hole, and an oil path that opens and closes depending on the position of the servo valve to flow oil from the pressure source to the pressure oil chamber or from the pressure oil chamber to the low pressure chamber. an operation main body comprising an electromagnetic operation unit that moves the servo valve, and a position detector that detects the position of the timer piston; a target value calculation unit that calculates a position; an actual value calculation unit that calculates an actual position of the timer piston according to at least an output from the position detection unit;
a target value correction section that corrects the target value from the calculation results of the target value calculation section and the actual measured value calculation section; and an output section that outputs a control signal according to the calculation result of the target value correction section to the electromagnetic operation section. A fuel injection timing control device comprising: a control body comprising;
