The invention concerns a fast valve actuator, comprising: a member driven (31) by a driving device (35) adapted to shift the driven member (31) by a travel (C1) to a triggering position; a locking and triggering means (31), co-operating with the driven member (31) and the actuating member (21) such that: during the travel (C1), the actuating member (21) should be stationary and the driven member (31) should be mobile; when the driven member (31) is in triggering position, the driven member (31) should be stationary and the actuating member (21) should be pushed by a prestressing means (51) to open or close the valve.
L'invention concerne un actionneur rapide de vanne, comportant :- un organe mené (31) par un dispositif d'entraînement (35) apte à faire passer l'organe mené (31) par une course (C1) à une position de déclenchement,- un moyen (41) de verrouillage et de déclenchement, coopérant avec l'organe mené (31) et l'organe d'actionnement (21) pour que : - dans la course (C1), l'organe (21) d'actionnement soit fixe et que l'organe mené (31) soit mobile, - lorsque l'organe mené (31) se trouve dans la position de déclenchement, l'organe mené (31) soit fixe et que l'organe (21) d'actionnement soit poussé par un moyen (51) de précontrainte pour l'ouverture ou la fermeture de la vanne.
