Abstract
(EN) The present invention provides an expansion joint for hydraulic connectors for connecting a first hydraulic line (41) to a second hydraulic line (42), comprising a fluidic communication chamber (1) securely connected, at a first end, to the first hydraulic line (41), wherein the first hydraulic line (41) is in fluidic communication with the interior of the fluidic communication chamber (1), and wherein the connection between the first hydraulic line (41) and the fluidic communication chamber (1) is of the sealed type; and a plunger (2) inside the fluidic communication chamber (1) connected hydraulically, via a sliding rod (3), to the second hydraulic line (42), wherein the sliding rod (3) is slidably connected to a second end of the fluidic communication chamber (1), and wherein the sliding rod (3) and the plunger (2) provide fluidic communication between the second hydraulic line (42) and the interior of the fluidic communication chamber (1).
(FR) La présente invention concerne un joint de dilatation pour raccords hydrauliques permettant de raccorder une première conduite hydraulique (41) à une seconde conduite hydraulique (42), comprenant une chambre de communication fluidique (1) raccordée de manière fixe, au niveau d’une première extrémité, à une première conduite hydraulique (41), la première conduite hydraulique (41) étant en communication fluidique avec l'intérieur de la chambre de communication fluidique (1), le raccordement entre la première conduite hydraulique (41) et la chambre de communication fluidique (1) étant du type étanche; et un piston (2) interne à la chambre de communication fluidique (1) raccordé hydrauliquement, par l'intermédiaire d’une tige coulissante (3), à la seconde conduite hydraulique (42), la tige coulissante (3) étant raccordée de manière coulissante à une seconde extrémité de la chambre de communication fluidique (1), la tige coulissante (3) et le piston (2) assurant une communication fluidique entre la seconde conduite hydraulique (42) et l'intérieur de la chambre de communication fluidique (1).
