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

A system for the reversible transformation of a reciprocating motion into rotary motion, comprising one or more actuating devices (11) actuated by a pressurized fluid and for cooperating with a rotor (3) having spiral section and which has at least one interaction surface for interact with said one or more actuating devices (11),

• wherein each actuating device (11) of said one or more actuating devices (11) comprises assembled internally a first and a second hydraulic cylinder (12;
• 13) each being independently slidable one relative to the other, and wherein each hydraulic cylinder (12,13) is coupled to elastic means (1);
• the arrangement being such that each actuating device (11) employs separately first elastic means (1) of a first hydraulic cylinder (12) and subsequently second elastic means (1) of said second hydraulic cylinder (13) to urge a tubular rod (6) coupled to said first and second hydraulic cylinder (12,13), said tubular rod (6) being associated to a head (4) that incorporates a slider (5), said slider (5) being adapted to transmit a thrust from said tubular rod (6) to said at least one interaction surface of said spiral rotor (3) creating thereby a torque onto said rotor (3).

A system for the reversible transformation of a reciprocating motion into rotary motion, comprising one or more actuating devices (601) adapted to cooperate with a rotor (603) having a spiral section and having at least one interaction surface for interacting with said one or more actuating devices (601),

• wherein each actuating device of said plurality of actuating devices (601) it is a pressurized fluid actuated cylinder and piston, and wherein each actuating device (601) it is associated to a rod (605) that incorporates a slider (606) that engages with said at least one surface of said rotor (603).
