Abstract

Frontal shutter comprising a rigid sealing ring carried by the free end of a resiliently deformable coaxial sleeve, the other end of the sleeve having means for mounting the sleeve hermetically on an element, in order to present the sealing ring for which is supported axially against an opposite face in another element, of relative rotation, the shape of the sleeve being practically unconstrued that of two axially opposite frustroconical parts of which the smaller diameters are at the ends of the sleeve, respectively, and the parts of larger diameter form a flexible circumferential unión about half the length of the sleeve, characterized in that a circumferential groove defining a pivotal joint for the frustroconical parts is provided around the circumferential flexible joint; a contractile ring sits in the grooves and the free end of the sleeve is supported on the sealing ring in order to preserve, in practice, the frustroconical shape of the adjacent sleeve part, thereby forming the sleeve a joint which, in practice, is exposed to a pressure (p) of the fluid to be sealed and exerts on the sealing ring an axial bearing load that depends on the axial lengths (0, 1, 12) and angles of conicity (0, 1) of the frustroconical parts and the ratio of the diameters of the ends of the sleeve.
