<p>The safety valve is sensitive to cancellation of the flow in a branch of a hydraulic circuit. The valve comprises a constriction (8) (Venturi tube) capable of being inserted in the hydraulic circuit to be monitored, a high-pressure chamber (12) communicating with the upstream end of the constriction, a low-pressure chamber (19) communicating with the downstream end of the constriction, and a delivery chamber (13) and a slide valve (15) regulating the communication between the chambers (12) and (19) as a function of the head loss in the Venturi tube (8). Application to the protection of a power-steering system. <IMAGE></p> |
