Abstract

Soupape limitatrice de pression pour étançon hydraulique de taille comprenant un piston de soupape (15) à gradins et présentant des alésages radiaux de décharge (18). Le piston de soupape (15) est soumis indirectement à l'action d'un ressort de soupape (22) qui agit sur un piston à ressort (19). Le piston à ressort (19) est guidé dans la douille formant logement (12) par son disque (20). Le disque (20) du piston comprend sur sa partie inférieure des surfaces déflectrices concaves (21).
