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.

Claim (Index 1):
A hydraulic rotary actuator, comprising:\n a fluid input; a fluid output; a main housing comprising a cavity, the cavity comprising a primary chamber and a secondary chamber; a first cover at least partially covering a first side of the main housing, the first cover comprising a cooling circuit formed in the first cover through which a hydraulic fluid flows; a second cover at least partially covering a second side of the main housing, the second cover comprising a cooling circuit formed in the second cover through which a hydraulic fluid flows; a rotational assembly positioned at least partly within the cavity of the main housing, the rotational assembly comprising:\n a hub, \n a first vane that moves within the primary chamber in response to the hydraulic fluid flowing into the primary chamber to impart rotational motion to the rotational assembly, \n a second vane that moves within the secondary chamber in response to the hydraulic fluid flowing into the secondary chamber to impart rotational motion to the rotational assembly, \n a first manifold providing a fluid connection between the primary chamber and the secondary chamber, the first manifold extending through at least a portion of the first vane and extending through at least a portion of the hub spaced apart from the axis of rotation such that the first manifold does not intersect the axis of rotation, and \n a second manifold providing a fluid connection between the secondary chamber and the primary chamber, the second manifold extending through at least a portion of the second vane and extending through at least a portion of the hub spaced apart from the axis of rotation such that the second manifold does not intersect the axis of rotation; and \n a mechanical connection that connects the rotational assembly to a device to be driven in rotational movement; wherein the vanes of the rotational assembly are not evenly spaced around the axis of rotation, and wherein the first and second manifolds are not in fluid communication.
