Abstract

SYSTÈME ANTI-OUBLI D’UN ÉLÉMENT FILTRANT Un aspect de l’invention concerne un dispositif de support de filtre sécurisé (1) pour turbomachine comprenant : un support (3) pour supporter un filtre amovible (21,21b) et un dispositif de présence de filtre anti-forçage (4) monté sur le support (3), comprenant : o un doigt de verrouillage (41) mobile entre une position sortie et une position finale, tel qu’en position sortie le doigt de verrouillage (41) fait saillie du support, o un pion anti-escamotage (42) comprenant une première protrusion de blocage (421), le pion anti-escamotage (42) étant mobile entre une position libre et une position occupée, le dispositif de support de filtre sécurisé (1) comportant : - une position dépourvue de filtre telle que le pion anti-escamotage (42) est en position libre, le doigt de verrouillage (41) en position sortie, de sorte que la première protrusion de blocage (421) empêche le doigt de verrouillage (41) d’être poussé vers la position finale, - une position d’installation d’un filtre supporté par le support (3), le filtre (21,21b) étant en appui contre le pion anti-escamotage (42) en position occupée, et le doigt de verrouillage (41) étant déplaçable manuellement vers la position finale, - une position de verrouillage dans laquelle le doigt de verrouillage (41) est dans le support (3) pour permettre le montage du dispositif de support de filtre sécurisé (1).
