Abstract:
A connection device which forms a seal between an inner element and a coaxial outer element with a central opening of a larger diameter than an outside diameter of the inner element which defines an annular space, the two elements rotating in relation to each another, allowing longitudinal and radial displacements between the two elements, the device comprising:a shell arranged in the annular space between the two elements with an outside diameter smaller than the central opening, at least one first seal, placed between the shell and the inner element and secured to the shell, at least one second seal placed between two opposite walls of the shell and of the outer element, extending radially relative to an axis of rotation, and a securing device including a ring secured to the shell comprising split fingers, members and springs, the springs cooperating with the members and pressing onto the split fingers of the ring which press the two opposite walls against each other through the second seal with an adjustable application force while allowing radial displacements of the shell with respect to the outer element, through a displacement of the split fingers with respect to the members.
