Abstract
The seal is composed of butt-jointed segments ( ) in which the bearing surface ( ) on a rotating part ( ) subject to wear, includes a hollow chamber ( ) communicating through calibrated orifices ( ) with a high pressure containment ( ). Therefore, it fills up with gas which tends to force it away from the surface, thus reducing the contact pressure without introducing excessive leaks.
