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