ABSTRACT:
Each of the head assemblies of a rotary actuator includes a tapered roller bearing in which the shaft of the actuator is journaled and an end plate against the inner face of which the stator and movable vanes of the actuator are sealed by a resilient jacket. A pressure equalizing passageway extends through each end plate from the cavity in which the associated roller bearing is mounted to the gasket which seals the stator to the end plate, thereby to equalize the pressure across the end plate and reduce the torque required to initially rotate the actuator shaft.
