ABSTRACT:
A coupling for connecting a movable link member of a valve actuator assembly to a movable valve spool in a fluid control valve includes a swivel spud secured to the end of the valve spool. The swivel spud has a semi-spherical outer end surface and first and second transverse apertures formed therethrough. A first cylindrical pin is retained within the first aperture of the swivel spud. The actuator assembly further includes a movable inner piston having an end portion, which is generally hollow and cylindrical in shape, and a pair of opposed apertures formed therethrough. The semi-spherical outer end surface of the swivel spud is received within the hollow end portion of the inner actuator piston. A second pin is retained in the opposed apertures of the inner actuator piston, extending through the second aperture of the swivel spud. When the inner actuator piston is moved in one direction, the pins engage one another to effect movement of the valve spool in that direction. When the inner actuator piston is moved in an opposite direction, the semi-spherical surface of the swivel spud engages a flat reaction surface of the inner actuator piston to effect movement of the valve spool in that direction.
