1. Sealing gasket provided to be placed in a groove (14) of a part (7) distant from a second part (4) by a space (23), an anti-extrusion rod (22) being inserted in a cut (21) of the gasket for bearing against a lateral side of the groove (20) and against the part (4), characterized in that it has a substantially rectangular cross-section, means being provided for maintaining it applied against the bottom (20) of the groove (14) and against one of the lateral sides of this groove so that it will extend through the space (23) and constantly bear in a resilient manner against the second part (4) by one of the small sides of a width/of the rectangle that it delimits, the means maintaining the part of a rectangular cross-section (19a) against one of the lateral surfaces of the groove (14) being formed by small bosses (25) separated by cells (28) and bearing on a lateral side of the groove (20) without bearing on the bottom of this groove or on the second part (4), and the means providing the maintenance of the anti-extrusion rod (22) and ofone of the sides of the rectangular part (19a) of the gasket against a lateral surface of the groove (14) being made by a pressurized hydraulic fluid. |
