SEALING ARRANGEMENT AND PROCESS FOR HERMETIC SYSTEMS

摘要

Sealing arrangement and process for hermetic systems of the type which comprises a hermetic shell portion (10), from which outwardly projects a supply tube (20) for supplying a load of working fluid to the inside of the hermetic system and which is subsequently sealed. Said supply tube (20) comprises a first and a second deformation (21, 22) axially spaced apart and each blocking the fluid flow cross section of the supply tube (20); a plug (30) made of a deformable material and which is housed inside the supply tube (20) between the first and the second deformations (21, 22); and at least one intermediary deformation (23) located between the first and the second deformations (21, 22) and deforming a median portion of the plug (30) in order to hermetically block the fluid flow cross section of the supply tube (20) between the first and the second deformations (21, 22).
