WIPO Patent Application WO/2023/046808
Kind Code:
A1
Abstract:
Device (10, 100) for sealing a leak in a pipe or reservoir wall (70) having an opening (80), comprising an elastomer plate (40) applied to the wall at the site of the opening, a force applicator (12, 14, 16, 50) and a force distributor (20) applied to the elastomer plate and means for applying a clamping torque to the force applicator. According to the main features of the invention, the force distributor (20) has an inner face (28) intended to be placed onto the elastomer plate (40), the inner face having an active zone corresponding to a protuberance (25) and an inactive zone situated around the protuberance, in such a way that, when the clamping torque is applied to the force applicator, the active zone generates a pressure on the elastomer plate greater than the pressure generated by the inactive zone of the distributor (20) on the elastomer plate.
