ABSTRACT:
The invention relates to a bleed valve for a hydraulic circuit, comprising a piston capable of sliding in a bore formed in a body and actuating a shutter arranged between two sub-circuits and movable between a first position, in which it allows communication between the two sub-circuits, and a second position, in which it prevents this communication, the shutter being movable under the effect of an external mechanical action exerted by an actuating member. According to the invention, the sealing between the bore and the outside of the body is ensured by the actuating member, and the shutter is movable under the effect of a difference between the pressures which are exerted on its two faces.
