Abstract
A rotating connection device forming a seal between an inner element ( ) and an outer element ( ) of larger diameter than the inner element, these two elements being co-axial, cylindrically symmetric and rotating in relation to one another. It comprises a shell ( ) placed in the annular space between the two elements, at least a first ring-type seal ( ) secured to the shell, placed between the latter and inner element ( ), at least a second ring-type seal ( ) placed between two opposite walls ( ) of shell ( ) and of outer element ( ), both perpendicular to the axis of rotation, and means ( ) for pressing the two walls against one another by means of the ring-type seal with an adjustable application force. This connection device allows substantial motions between the two elements, radial as well as longitudinal. The device can be used: for example for connecting a pipe linking an outer device and the central part of the rotating ring gear of a heat exchange and/or incineration system.
