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, and means for returning the obturator towards its closed position.

Machine comprising a circuit for supplying pressurised fluid, wherein the circuit comprises a safety valve comprising a body and an obturator movable in the body between a closed position and an open position, the valve comprising displacement means for displacing the obturator towards the closed position when the pressure of the fluid supplying the machine is lower than a threshold value, and wherein the displacement means comprise:
- a piston for driving the obturator towards the open position, the piston being in contact with the pressurised fluid supplying the machine when the obturator is in the open position, and
- return means for returning the obturator towards the closed position.
