Abstract (en)
[origin: WO2017064438A1] The fluid valve (10) with hysteresis, comprises: a needle valve (26) capable of adopting at least one closed position and one open position, a piston (30) sensitive to the fluid flow and able to adopt at least one low-flow position and one high-flow position. The needle valve (26) and the piston (30) are arranged in such a way that as long as the piston (30) is in the high flow position, the needle valve (26) is prevented from occupying the closed position.
