Abstract

L'invention concerne une microsoupape fendue qui comprend un obturateur de soupape (3) et un corps de soupape (1,4). Le corps de soupape (1,4) est une structure fendue et comprend un corps de soupape avant (1) et un corps de soupape arrière (4). Le corps de soupape avant (1) comporte une chambre de soupape (10) qui comprend une sortie de liquide (5) à une extrémité et un filetage intérieur (6) à l'autre extrémité. Le corps de soupape arrière (4) comprend une entrée de liquide (9) à une extrémité et un filetage extérieur (8) à l'autre extrémité. Le filetage intérieur (6) du corps de soupape avant (1) est relié de manière filetée au filetage extérieur (8) du corps de soupape arrière (4). Le corps de soupape arrière (4) comprend un siège de soupape (7) au niveau de son extrémité filetée. Un obturateur de soupape (3) est situé à l'intérieur de la chambre de soupape (10), et coopère avec le siège de soupape (7) du corps de soupape arrière (4). Le corps de soupape (1,4) peut être assemblé facilement et la taille de la chambre de soupape (10) peut être modifiée en remplaçant le corps de soupape avant (1).
