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.at. Valve combining a pressure limiting valve and a check valve. b. Valve characterized in that the connection introducing the pressure to be limited is the connection mounted laterally with respect to the main control body, while the main valve body has at least one bore which, in each position of this main valve body, connects the lateral connection to the space situated behind the valve body, the pressure against which the valve is to act as a check valve being introduced by the connection leading axially to this valve body. vs. The invention applies in particular to the control of hydraulic motors.
