Zusammenfassung:The invention relates to a quick-acting valve actuator comprising: a driven member ( 31 ) driven by a drive device ( 35 ) suitable for causing the driven member ( 31 ) to travel along a stroke (C 1 ) to a trigger position; and locking-and-trigger means ( 41 ) co-operating with the driven member ( 31 ) and the actuator member ( 21 ) so that: during the stroke (C 1 ), the actuator member ( 21 ) is stationary, and the driven member ( 31 ) is moving; and when the driven member ( 31 ) reaches the trigger position, the driven member ( 31 ) is held stationary, and the actuator member ( 21 ) is urged by prestress means ( 51 ) to open or close the valve.
