Abstract
A hydraulic actuator for a multicylinder Stirling engine provided to enable modulation of the displacement of the engine. The hydraulic actuator incorporates a rotary vane configuration which provides relative rotational adjustment between components of a swashplate assembly. The relative rotation provides adjustments to the angle formed by the swashplate relative to its angle of rotation, and thus varies the stroke of each piston connecting rod, which thereby modulates the swept volume of the respective piston within its cylinder bore.
