Inflatable seal
EYRBALL Eynard Robin Etanchéité

Inflatable joints EYRBALL consist of an envelope in
étastomère (generally out of silicone or EPDM) inflatable with the means
of a valve. They are carried out starting from welded extruded profiles then.
They make it possible to ensure the étanchéitô between two variable components, them
operation is characterized by two distinct physical statuses b>en.
1-state of rest or retracted: The joint is inside its housing,
thus allowing the displacement of the variable component. For reasons
obvious of safety, the joint is always assembled slightly in withdrawal
throat.
2 - State of work or expanded: The joint is developed thanks to the action
fluid of inflation (water. has", gas or oil...) ensuring as follows:
- the sealing enters the interior and the outside of the mechanical system.
it blocking of the variable component.
These two functions take place thanks to the clean elasticity of elastomer.
