Abstract
This present invention relates to a remote electro-hydraulic actuator for actuating of mechanical devices, such as a valve in an internal combustion exhaust pipe. The actuator includes a multi-vane rotational assembly that flows the working fluid through strategically sized flow channels within the structure of the rotational assembly. The size of the holes are sized to help the stability of the valve and can also be provided with pressure check valves or reed valves to dampen the rotation of the valve and reduce any instabilities due to pulsations driven back via the output shaft.
