ABSTRACT:
A hydraulic servomechanism permitting a wrist like universal motion of an extending member through a generally hemispherical operating range in which a sphere or sphere-like drive member is mounted for movement in a spherical or sphere-like cavity and driven by fluid pressure in intersecting circumferential channels mounted either in the drive member or the support means. The circumferential channels are sealed by curved metal bands with gaskets along the edge. Hydraulic fluid enters the channels through ports in the sealing bands themselves so as to facilitate easier movement of the drive member.
