System for the reversible transformation of a reciprocating motion in a rotary motion

A system for a revisable transformation of a reciprocating motion into rotary motion, comprising one or more of actuating devices adopted to cooperate with a rotor having a spiral section and having at least one interaction surface for interacting with said one or more actuating devices;

• wherein each actuating device of said one or more actuating devices comprises a pressurized fluid actuated cylinder and head, and wherein each actuating device is associated with a rod that incorporates a slider engaging with said at least one interaction surface of said rotor, wherein the slide rotatably mounted onto the head, and the head is slidably mounted on the rod;
• wherein the one or more actuating devices are actuated by the pressurized fluid, wherein each hydraulic cylinder and head of a respective actuating device of said one or more actuating devices comprises a first and a second hydraulic cylinder coaxially assembled internally of said first hydraulic cylinder, each being independently slidable relative to one another, and wherein each of said first and second hydraulic cylinder is coupled to an elastic means;
• and,
• wherein each actuating device is configured to employ separately first elastic means of a first hydraulic cylinder and subsequently second elastic means of said second hydraulic cylinder to urge a tubular rod coupled to said first and second hydraulic cylinder, said tubular rod being associated with a head that incorporates the slider, said slider being adapted to transmit a thrust from said tubular rod to said at least one interaction surface of said spiral rotor creating thereby a torque onto said rotor.
