Abstract

PURPOSE:To accurately perform the adjusting work on the gap located between a stroke and ratehes in a short time by a method wherein a constitution is provided in such manner that a stopper material is not contacted to the nut of the plunger to be fixed to a movable core using a nut. CONSTITUTION:The nut 5a of the plunger 5 to be pressed by stopper bolts 14's having the movable core 4 as their stopper member and to be fixed on the movable core 4 with a nut, is released from the stopper member. the gap (g) located between ratches can be adjusted by loosening the nut 5a and rotating the plunger 5 whthout giving an effect on the storke S. Also the stroke S can be adjusted independently from the gap (g) located between ratches by loosening 14a's and by rotating stopper bolts 14's.
