Title (EN) VALVE WITH SHAPE MEMORY ALLOY WIRE
(FR) VALVE AVEC FIL D'ALLIAGE À MÉMOIRE DE FORME
Abstract:
(EN) A valve (100) includes a housing (111) and the fluid port (121). A plunger (125) is configured to seal the fluid port (121) in a first position (91) and to unseal the fluid port (121) in a second position and to displace along a displacement direction (259) from its first position (91) towards its second position. The valve (100) also includes at least one shape memory alloy, SMA, actuator (151, 152) extending along the displacement direction (259) for at least 50% of its length and configured to exert an actuation force (155) on the plunger (125) to displace the plunger (125) from the first position (91) towards the second position.
(FR) L'invention concerne une valve (100) comprenant un boîtier (111) et un orifice de fluide (121). Un piston plongeur (125) est conçu pour sceller l'orifice de fluide (121) dans une première position (91) et pour libérer l'orifice de fluide (121) dans une seconde position et pour se déplacer le long d'une direction de déplacement (259) de sa première position (91) vers sa seconde position. La valve (100) comprend également au moins un actionneur (151, 152) en alliage à mémoire de forme, SMA, s'étendant le long de la direction de déplacement (259) sur au moins 50 % de sa longueur et conçu pour exercer une force d'actionnement (155) sur le piston plongeur (125) pour déplacer le piston plongeur (125) de la première position (91) vers la seconde position.
