Zusammenfassung:	A bellows energized seal assembly (150) includes a seal body (154), a main seal (152) that is axially slidable within the seal body (154), and a bellows (156) connected to the seal body (154) and the main seal (152). The bellows (156) both biases the main seal (152) and provides a seal between the seal body (154) and the main seal (152). La présente invention concerne un ensemble de joints activé par soufflet (150) comportant un corps de joint (154), un joint principal (152) qui est apte à un coulissement axial dans le corps de joint (154), et un soufflet (156) connecté au corps de joint (154) et au joint principal (152). Le soufflet (156) sollicite le joint principal (152) tout en fournissant une étanchéité entre le corps de joint (154) et le joint principal (152).
