Abstract

a. Soupape combinant une soupape de limitation de pression et une soupape de retenue. b. Soupape caractérisée en ce que le branchement introduisant la pression à limiter est le branchement monté latéralement par rapport au corps de commande principal, tandis que le corps de soupape principal comporte au moins un alésage qui, dans chaque position de ce corps de soupape principal, relie le branchement latéral à l'espace situé en arrière du corps de soupape, la pression par rapport à laquelle la soupape doit agir comme soupape de retenue étant introduite par le branchement menant axialement à ce corps de soupape. c. L'invention s'applique notamment à la commande des moteurs hydrauliques.
