Abstract

PURPOSE:To hold pressure setting value at on and off parts not to be varied, by a method wherein a laminated metal diaphragm is constituted by interposing oil or antiabrasion powder between individual diaphragms of the laminated diaphragm. CONSTITUTION:A laminated metal diaphragm is constituted by interposing oil or antiabrasion powder between individual diaphragms or by applying oxide film to surface of metal diaphragms 31-35 and then interposing oil or antiabrasion powder (e.g. molybdenum disulfide) 5 between individual diaphragms. In this constitution, even if snap action is carried out more than prescribed times, pressure setting value at on and off parts can be held not to be varied.
