The valve operator assembly is provided for a valve and comprises a housing 18, an input member 20 rotatably mounted with respect to said housing and comprising a rotational drive input 72, and a transmission mechanism 22 connected to said input member and comprising a stem 24, said transmission mechanism being adapted to convert applied rotation of the rotational drive input into axial translation of said stem. The assembly further comprises at least one elastic actuator 33 axially located between the input member 20 and the stem 24 to obtain a compression of the actuator during an axial translation of said stem towards the input member and a release of said actuator during an axial translation in the opposite direction. |
