Abstract

L'invention porte sur une machine de perméabilité (8) destinée à effectuer un test de perméabilité d'un joint à labyrinthe (1) comportant: - une cartouche (20) comportant un premier élément (2) dudit joint à labyrinthe (1) muni de léchettes dit "élément à léchettes", et - au moins un support (21) portant un deuxième élément (5) dudit joint à labyrinthe (1) réalisé dans un matériau abradable, dit "élément abradable", et - un système (27) de réglage d'un jeu entre l'élément à léchettes (2) et l'élément abradable (5) configuré de telle façon qu'un mouvement de rotation d'une molette de réglage (28) engendre un déplacement en translation suivant une première direction d'un coulisseau (38) lequel déplace en translation un support (21) de l'élément abradable (5) suivant une deuxième direction de manière à pouvoir faire varier de façon continue le jeu entre l'élément abradable (5) et l'élément à léchettes (2). Figure 4The invention relates to a permeability machine (8) intended to carry out a permeability test of a labyrinth seal (1) comprising: - a cartridge (20) comprising a first element (2) of said labyrinth seal (1) provided with wipers called "wiper element", and - at least one support (21) carrying a second element (5) of said labyrinth seal (1) made of an abradable material, called "abradable element", and - a system ( 27) for adjusting a clearance between the wiper element (2) and the abradable element (5) configured in such a way that a rotational movement of an adjustment wheel (28) generates a following translational movement a first direction of a slider (38) which moves in translation a support (21) of the abradable element (5) in a second direction so as to be able to continuously vary the play between the abradable element (5) and the wiper element (2).
