ABSTRACT:
The present invention relates to a crank system for the transformation of reciprocating linear motion into rotary motion, particularly suitable for reciprocating endothermic engines, comprising a wheel or rotating connection rod (2), idly provided on the engine piston (5) pin (3), and a cam (1), provided on the output shaft (6), having a perimetric profile made up of at least two segments or cam arches for the optimisation of the engine cycle strokes, said wheel (2) rotating along the profile of said cam (1) with a coupling characterized by the absence of friction or by a minimum friction.
