Abstract

Le clapet principal 21 de cette soupape contient une soupape pilote 25, 26, 29 qui peut être commandée par un poussoir 11. L'invention permet d'utiliser une petite soupape pilote qui peut être commandée par de petits efforts, appliqués par un poussoir Il dont la partie avant ne risque pas d'être faussée ou cassée. Selon l'invention, la partie avant du poussoir 11 présente un épaississement conique de renforcement et des surfaces de détente et l'extrémité 33 du clapet principal 21 présente un évasement conique 31 correspondant, de sorte que la partie avant du poussoir Il peut être aussi courte que possible. L'invention est applicable aux installations hydrauliques.
