Abstract

Carter comprenant une paroi (2) définissant un orifice (3) débouchant dans une veine et une vanne de décharge comprenant une porte comprenant un premier battant (10) mobile par rapport à la paroi, et un deuxième battant (20) mobile par rapport au premier battant (10), la porte étant configurable dans :- une configuration fermée dans laquelle le premier battant (10) obstrue une première portion (13) de l’orifice et le deuxième battant obstrue simultanément une deuxième portion (23) de l’orifice,- une configuration intermédiaire dans laquelle le premier battant (10) dévoile la première portion de l’orifice (13) pour permettre le passage de fluide, et le deuxième battant (20) obstrue la deuxième portion (23) de l’orifice, et - une configuration ouverte dans laquelle le premier battant (10) dévoile la première portion (13) de l’orifice, et le deuxième battant (20) dévoile simultanément la deuxième portion (23) de l’orifice. Figure pour l’abrégé : Fig. 2Housing comprising a wall (2) defining an orifice (3) opening into a vein and a discharge valve comprising a door comprising a first leaf (10) movable relative to the wall, and a second leaf (20) movable relative to the first leaf (10), the door being configurable in:- a closed configuration in which the first leaf (10) obstructs a first portion (13) of the orifice and the second leaf simultaneously obstructs a second portion (23) of the orifice, - an intermediate configuration in which the first leaf (10) reveals the first portion of the orifice (13) to allow the passage of fluid, and the second leaf (20) obstructs the second portion (23) of the orifice , and - an open configuration in which the first leaf (10) reveals the first portion (13) of the orifice, and the second leaf (20) simultaneously reveals the second portion (23) of the orifice. Figure for the abstract: Fig. 2
