Hydraulic assembly device, system and method

A hydraulic assembly comprising:

• a housing having a central axis;
• a rotor located along the central axis;
• a first thrust plate mounted at in the housing at a first housing end around the rotor at an angle other than 90 degrees to the central axis;
• a second thrust plate mounted at in the housing at a second housing end around the rotor at the same angle as the first thrust plate;
• and
• double-acting hydraulic actuators slideably mounted between said first and said second thrust plates and fixed to the rotor;
• wherein said double-acting actuators comprise:
• a first set of actuators fixed to a rotatable shaft and engaging said first thrust plate,
• a second set of actuators fixed to the rotatable shaft and engaging said second thrust plate,
• a piston head having a first face on said first side of said double acting actuators and a second face on said second side of said double acting actuators,
• a first push rod extending from said first face and a second push rod extending from said second face, the piston head mounted in a chamber that defined in a bore in the rotor and ported for hydraulic insertion and exhaust between both piston head faces and the chamber;
• wherein said rotor includes a radial port for each chamber of each actuator;
• the hydraulic actuator further comprising:
• pressure channels longitudinally spaced along said rotor and 180 degrees opposite each other and around said rotor wherein:
• a first of the pressure channels is in fluid communication with the radial ports on a first side of a plurality of pistons and
• a second of the pressure channels is in fluid communication with the radial ports on a second side of the plurality of pistons;
• exhaust channels longitudinally spaced along a ported casing wherein:
• each of the said exhaust channels is located opposite one of the pressure channels;
• and
• the exhaust channels are in fluid communication with ports that are not in fluid communication with said pressure channel;
• an I/O casing located around the rotor, the I/O casing comprising:
• a first pressure orifice and a first exhaust orifice spaced longitudinally along the I/O casing;
• wherein said first pressure orifice is in fluid communication with a first pressure groove in an interior face in said I/O casing that extends less than half the circumference of said I/O casing and
• wherein said first exhaust orifice is in fluid communication with a first exhaust groove in an interior face in said I/O casing that extends less than half the circumference of said I/O casing;
• a second pressure orifice and a second exhaust orifice spaced longitudinally along the I/O casing and opposite said first pressure orifice and said second exhaust orifice;
• wherein said second pressure orifice is in fluid communication with a second pressure groove in an interior face in said I/O casing that extends less than half the circumference of said I/O casing and
• wherein said second exhaust orifice is in fluid communication with a second exhaust groove in an interior face in said I/O casing that extends less than half the circumference of said I/O casing;
• and
• wherein said pressure and exhaust channels are defined between the pressure and exhaust grooves in said I/O casing and face of said rotor;
• a set of spherical ball connectors;
• a set of slider components having a flat side and a concave side of the same diameter as the spherical portion of the spherical ball connectors, wherein:
• said rods are each capped by one of the spherical ball connectors and one of the slider components receiving a portion of the spherical ball connectors in the concave side, and
• the flat side of each slider component is in contact with a portion of one of said thrust plates.
