Abstract:
An articulated coupling is provided for a piston sealing device for a piston which includes a fixed skirt and a sliding skirt interconnected by a mechanical inter-skirt connection for axially compressing a continuous extensible segment under the action of a sliding skirt spring, the coupling replacing, on the one hand, the fixed skirt by a ball-joint skirt and providing, on the other hand, a troncospherical piston end which cooperates with a skirt troncospherical bearing surface provided on the ball joint skirt while an articulation unit interposed between the inter-skirt mechanical connection and the piston and/or between the connection and the sliding skirt.

Claim (Index 14):
The articulated coupling according to  claim 1 , characterized in that the piston ( 3 ) comprises, at its periphery and in the vicinity of the troncospherical piston end ( 21 ), a dislocation abutment ( 46 ) which can come into contact with the cylinder ( 4 ) if the contact between the skirt troncospherical bearing surface ( 24 ) and the troncospherical piston end ( 21 ) is totally or partially broken.
