  • Roller screw actuator for subsea choke or module
    Patent number: 6585227
    Abstract: An actuator for use with a subsea choke or similar apparatus is disclosed. The actuator uses a planetary roller screw mechanism to allow greater control of the torque output while allowing a fast closing of the choke when well conditions require so. A handle is positioned on one end of the actuator housing for manipulation of the actuator housing by a remotely operated vehicle, when required. A pressure responsive axially reciprocable piston is positioned around the driven shaft and controls movement thereof. Other embodiments show the actuator controlling the position of the cage in a cage type choke. A final embodiment shows the actuator configured for use on a subsea tree.
