Abstract

PURPOSE: To enhance the accuracy of positioning of a plunger, by elastically supporting both the ends of the control valve of an injection time controller for a diesel engine or the like to apply a checking force to a motor.
CONSTITUTION: When a plunger 31 is moved leftward out of a balanced state in neutral position to advance injection time, a left-hand spring 40' acts to apply a checking force and the force of a timer piston 21 energized by a spring 40 becomes extremely greater than that of a motor 32 to that the driving force of the moror 32 and the checking force of the spring 40' are balanced to each other and the movement of the plunger 31 is stopped when the spring 40' is deflected to a prescribed extent. Since the cross-sectional area of passage openings 24a, 24b become unbalanced to each other due to the movement of the plunger 31, the pressure balance between a high pressure chamber 23 and a low pressure chamber 25 is eliminated at the next moment so that the timer piston 21 is moved leftward following the plunger 31. For that reason, the spring 40' loosens again so that the plunger 31 is moved leftward further. Such steps are repeated to move the plunger 31 to an objective position.
