The force limited valve actuator operates on light-duty valves. The actuator includes signal controlled motor which drives a two piece threaded screw-nut drive. The nut connected to the motor and the screw connected to the valve stem. The nut has a spring loaded actuation surface/plate. The nut body has a positional indicator stem used as a valve-motor control. Operationally, the screw-nut-set moves between first, second and third positions. First: actuation plate at neutral and valve-stem at valve OPEN stop (example). Second: screw protrudes outboard of nut and valve-stem at CLOSE stop and actuation plate at neutral. Third: plate moves away from valve-stem (beyond neutral) while stem at CLOSE which third movement is a force sensor. First, second and third positions are all one way screw rotation. Force limited on stem by damper-shock absorber action. The positional indicator effects ON-OFF valve control.

Force limited valve actuator and method therefor

An actuated support frame for transmitting motion to a seat with respect to a ground as a function of motion signals associated with video output, comprises a frame. The frame is expandable/retractable along translational degrees of freedom. Support surfaces are provided on the frame. The support surfaces are displaceable with respect to one another by expansion/retraction of the frame so as to be sized to support a seat. Actuators are provided between the frame and the ground. The actuators receive signals and selectively displace the frame with respect to the ground in synchronization with a video output, whereby a seat supported on the frame is displaceable within the frame. A method for installing a seating system of a motion simulator system is also provided.
