Definitions
- the lubricating fluid is for example grease or oil.
- the temperature differential for breaking the breakable zone is for example between 200 and 500 ° C.
- the assembly is made of a single piece of nickel-based alloy, for example a C263 type alloy.
- a stress can be generated mechanically at the connecting wall 22, for example by an operator, in particular by applying a shock or a sufficient force on said partition 22.
