Abstract

Rotary fluid shutter, to prevent leakage of fluid between two coaxial elements of relative rotation, of the type comprising a. Flexible circular sealing ring freely positioned to engage in a substantially coaxial manner between opposite axially opposed surfaces of the relative rotation elements, the sealing ring having a pair of annular sealing lips, radially diverging outwards and directed axially in opposite directions, to rest resiliently against the opposing surfaces, respectively, so that the sealing ring is driven by friction, to effect a rotation movement by the action of one or other of the elements after their relative rotation, characterized in that the sealing lips present each one, to the respective counter surface, a fustroconical contact face defined by radially inner and outer peripheral edges, and the opposing surfaces are radially diverging outwardly and fustroconically to make a surface contact with the contact faces is placed in a practical way coaxially by settlement between the opposing surfaces, the effect being the centrifugal force due to the rotation of the sealing ring, which tends to cause the sealing lips to be subjected to angular flexure, projecting outwards and towards a plane radial, that of reducing the support load of the contact faces on the opposite surfaces.
