RELIEF PRESSURE ADJUSTER

摘要

PURPOSE:To prevent the danger of wrong operation, by providing a spacer on the back of a support for an elastic member so that the motion of the elastic member in the direction of elongation and contraction is limited to a prescribed quantity and by providing a bolt to adjust the position of the spacer. CONSTITUTION:A spacer 6 is inserted to the back of a member 4 which supports a relief spring 3. A pressure adjustment bolt 8 is screwed into a spacer holder 5 and a spacer cover 7 so that the adjustment of relief pressure is limited within a range from a minimum pressure level to a maximum pressure level. This results in preventing the danger of wrong operation or the like.
