Definitions

• the present invention is related with realizing the production of a more efficient, more powerful and more environment friendly high speed motor, with a spring mechanism that elongates the crank moment arm, independent from the piston stroke and crank shaft rotational circumference in the internal-and external- combustion motors.
• the moment arm length is equal to the radius of maximum crank shaft rotation circumference or to the half of the piston stroke.
• the object of the present invention is to elongate the moment arm in internal and external combustion motors with pistons, by changing the center of the connection rod (4) to the utility direction whereas the two eccentrics in the connection rod (4) and crank shaft center remain fixed, wherein the crankshaft arm axis to which the connection rod (4) is joined and the connection rod (4) axis also remain fixed; and consequently a more environment friendly, more efficient and more powerful high-speed motor production is realized.
• Figure 1 shows the components of the spring mechanism
• Figure 2 shows the crank peg axis, small eccentric axis and big eccentric axis (connection rod axis) at the rotated positions of the crank shaft at 0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°, 360°.
• connection rod center 18) Larger eccentric centers at eight different points (connection rod center) 19) Shows the path (route) of the connection rod center
• the spring mechanism that enhances the motor power, torque and speed by elongatine the crank moment arm, in internal and external combustion piston motors, consists of two coaxial eccentrics (5 and 6) placed on the crank peg (7) in the connection rod (4), and a guiding arm (6) connected directly to the small eccentric piece moving in connection with these eccentrics, a spring compressing arm (5) and spring compressing mechanism (8) directly connected to the larger eccentric, and a spring (11) one end of which is connected to the spring compression mechanism (8) and the other end, to the motor body.
• the guiding arm (5) manufactured with one end fixed to the smaller eccentric, is provided with a channel (15) on its other end.
• the guiding support ball (16) connected to the motor body is engaged into the said channel (15).
• the eccentric (6) moves in connection with the support in the connection rod (4).
• the center of the connection rod (4) changes, furthermore, the spring compression mechanism (8) and the assembly that facilitates the compression of the spring (11) moves around the axis, proportionally as much as the compression arm (5) and the spring compression allows, by being supported from the spring compression axis or from any suitable location.
• the compression spring assembly consists of the larger eccentric and the guiding arm (5) fixed to it, a sliding roller bearing for the spring compression mechanism (13), spring compression joints (12), spring (11), crank shaft rotation circumference (10), smaller eccentric guiding support roller (15) and spring compression mechanism (8).
• the piston (2) pressure acting on the connection rod (4) is greater than the pressure action on the piston (2) at angular positions, due to the eccentrics inside the connection rod (4).
• the pressure turning the crank shaft (20) is more and the moment arm (length t) is longer; thus providing positive gain in significant amounts.
• the spring (11) on the spring compression arm (5) acting on the arm from the spring compression mechanism (8) is fixed and the effect point acting on the crank peg (7) is movable, while tightening the spring (11), the spring (11) can be compressed with a larger moment arm. After the tightening of the spring (1 1) the moment arm remains constant with respect to the support point whereas the other arm is far shorter than the arm which tightened the spring. This situation provides numerous advantages with respect to moment arm and spring selection.
• crank shaft axis and the cylinder (1) and piston (2) driving axis are completely different; this difference causes the piston (2) to provide more effective action of the pressure inside the cylinder (1) in the positive direction.
• the difference between the crank peg (7) center and the connection rod (4) center holds the piston (2) at a position, higher than that of the crank peg (7) and therefore it is more effected by the pressure created by the explosion in the cylinder.
