A Study on the Diaphragm Used for an Accumulator Regarding its Behavior in Low Temperature Conditions

In a diaphragm used for an accumulator, the relationship between design factors and durability in low temperature is discussed from the occurrence of buckling phenomenon through the observation results.

The durability of the diaphragm which has a sandwich structure of rubber and resin films, is greatly influenced by the buckling phenomenon which occurs during deformation of the diaphragm when used for an accumulator in low temperature condition.
