Abstract

Improvements in rotary mechanical surface joints, of the type comprising two concentric sealing surface elements pushed axially in contact with an axially fixed seat, with a coolant present in the annular space between the two elements, where at least one of the two sealing surface elements, which are in contact with a fluid against which the seal is intended to act, are hermetically sealed to their associated component by means of a flexible bellows.
