Patent ID: 8545351

Claim:
A bent tensioner with high damping device for a combustion engine, comprising: a hinged or eccentric arm ( 3 ) having a first end ( 3 A) coupled to a stretching set and a second end ( 3 B) coupled to a damping set, said damping set comprising a rubber device ( 2 ), a base ( 4 ), a sliding bush ( 5 ), a protection gasket ( 6 ), and a retention ring ( 7 ), characterized by the rubber damping device ( 2 ) being gear-shaped, containing one central cylindrical hole ( 2 A) and four symmetrical sections with four deep “U” shaped cavities ( 2 B) and four shallower cavities ( 2 C); wherein the hinged arm ( 3 ) is oblong shaped, the first end ( 3 A) having a smaller diameter and comprising a ring ( 3 A 1 ) and a coupling pin ( 3 A 2 ) for coupling to the stretching set; and the second end ( 3 B) having a larger diameter comprising a cylindrical upper opening ( 3 B 1 ), cylindrically thinner towards the center ( 3 B 2 ), forming the internal wall of a lower cylindrical pin ( 3 C) to which the rubber damping device ( 2 ) is coupled, as well as two prolongations or columns ( 3 D) located in parallel near the sides of the lower cylindrical pin ( 3 C) with rounded internal corners ( 3 D 1 ) for locking and damping the rubber damping device ( 2 ); wherein each of the deep “U” shaped cavities ( 2 B) is between the symmetrical sections and each of the shallower cavities ( 2 C) is in one of the symmetrical sections; wherein the base ( 4 ) is formed by a circular platform ( 4 A), said platform ( 4 A) having a central cylindrical pin ( 4 B) located in the center with upper gutters ( 4 B 1 ) and side ridges having two wall sections ( 4 C), each one with two columns ( 4 D), with rounded internal corners ( 4 D 1 ) acting as a guide for fitting the rubber damping device ( 2 ) wherein the tensioner set is formed by a pulley (B) with rollers (C), a dust-coat cap (D) and a bolt (A).
