を特徴とするタイマの測定具。 The actuator is constructed by fitting a piston that supports a servo valve into a cylinder that crosses the pump body, and the rotational displacement of the roller holder of the cam mechanism that reciprocates the plunger is transferred from the oil pump to the high pressure chamber of the actuator via the servo valve. In the timer of a distributed fuel injection pump controlled by the applied fuel pressure, a guide tube with a spring seat is coupled to the side wall of the pump body to close the low pressure chamber of the actuator, and the guide tube is inserted through the spring seat. 1. A measuring device for a timer, characterized in that a U-shaped body is supported in contact with a piston, and a weak spring is interposed between a detection rod connected to the U-shaped body and an end wall of a guide cylinder.
