ABSTRACT:
The safety valve comprises a body and an obturator movable in the body between a closed position (FIG.2) and an open position (FIG.3). It also comprises means for displacing the obturator in order to displace it towards its closed position when the pressure of the fluid is lower than a threshold value, and the displacement means comprise:a piston for driving the obturator towards its open position, the piston being in contact with the pressurised fluid when the obturator is in the open position, andmeans for returning the obturator towards its closed position.Application, for example, to pneumatic machining machines.
