Abstract
System for the reversible transformation of a reciprocating motion in a rotary motion, which may include one or more actuating devices adapted to cooperate with a rotor which has a spiral shaped section, and has at least one interaction surface for interacting with said one or more actuating devices. Each actuating device of said plurality of actuating devices is an internal combustion cylinder and piston device. Each actuating device is associated with a rod which incorporates a slider with a follower which engages with said at least one interaction surface of said rotor.

A system for the reversible transformation of a reciprocating motion in a rotary motion, which comprises one or more actuating devices (50) adapted to cooperate with a rotor (53;
- 63) having a spiral shaped section, and which has at least one interaction surface (52, 62) for interacting with said one or more actuating devices (50),
- characterized in that each actuating device (50) of said plurality of actuating devices (50) is an internal combustion cylinder and piston device, and wherein each actuating device (50) is associated with a rod (56) which incorporates a slider (5) which engages with said at least one interaction surface (52) of said rotor (53;
- 63), wherein the rotor (53) includes a constant diameter profile section (55), the arrangement being such that during operation said constant diameter profile section (55) keeps the piston in a stopped position at the top dead center T.D.C. for a combustion phase, thus ensuring complete combustion at constant volume.
A system for the reversible transformation of a reciprocating motion in rotary motion, which comprises one or more actuating devices adapted to cooperate with a rotor in an engine block, the rotor having a spiral profiled cross section comprising at least one ramp and which has at least one interacting surface with said one or more actuating devices, wherein each actuating device of said plurality of actuating devices is an internal combustion piston cylinder which incorporates a rod and a slider or follower, and wherein a lever mechanism is provided by which the piston return stroke is performed at the top dead center T.D.C. in the compression phase, said lever mechanism comprising a lever connected in an oscillating manner with said engine block and the lever being fork shaped, said fork having a slider at the end thereof and adapted to cooperate with said interaction surface of said rotor, and wherein said end of said fork lever being adapted to interact with the slider of the piston rod, and wherein during the approach of the rod to said ramp, said lever rises and returns the piston to the T.D.C., and wherein when the cursor reaches the T.D.C. of the piston, said lever disengages from said rod and returns to its initial position.
A system for the reversible transformation of a reciprocating motion in rotary motion, which comprises one or more actuating devices adapted to cooperate with a rotor in an engine block, the rotor having at least one interacting surface with said one or more actuating devices, said rotor (53;
- 63) having a spiral shaped section, and which has at least one interaction surface for interacting with said one or more actuating devices (50),
- wherein each actuating device (50) of said plurality of actuating devices (50) is an internal combustion cylinder and piston device, and wherein each actuating device (50) is associated with a rod which incorporates a slider which engages with said at least one interaction surface of said rotor (53;
- 63),
- wherein the rotor (53) includes a first constant diameter profile section (55), the arrangement being such that during operation said a constant diameter profile section (55) keeps the piston in a stopped position at the top dead center T.D.C. for the combustion phase, thus ensuring complete combustion at constant volume, and
- wherein the rotor (53) includes a second constant diameter profile section (65) extending from the exhaust valve opening position to the initial compression phase position, the arrangement being such that the piston is kept in a stopped position at the bottom dead center B.D.C. for the complete waste/washing/filling phase of the cylinder,
- wherein said rotor includes a compression ramp (64), and an expansion section of the spiral profile (62) of the rotor (63).
