Title (EN) FLUID VALVE WITH HYSTERESIS
(FR) VANNE FLUIDIQUE A HYSTERESIS
Abstract:
(EN) 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.
(FR) La vanne fluidique à hystérésis (10), comprend: un clapet (26) apte à prendre au moins une position fermée et une position ouverte, un piston (30) sensible au flux de fluide apte à prendre au moins une position débit faible et une position débit élevé. Le clapet (26) et le piston (30) sont agencés de manière à ce que tant que le piston (30) est en position débit élevé, le clapet (26) est empêché d'occuper la position fermée.
