Seal for component passing through wall of thermally insulated housing comprises bellows with non-elastic truncated conical upper section

摘要

The seal consists of lower and upper coupling members (4, 5) connected by a bellows which has its upper section (6) in the form of a non-elastic truncated cone. The bellows is designed to be resistant to temperatures down to -50[deg]C and to allow a relative movement between the two coupling members of at least 15 cm, and preferably at least 20 cm.
