ABSTRACT:
A modular camshaft comprises at least two modular elements or modules removably coupled together; each module carries at least one cam and comprises two cylindrical elements disposed on the same axis and projecting in opposite directions from opposing faces of said cam, a first cylindrical element acting as a hub and the second being hollow and acting as a seat, the seat of one modular element being arranged to receive the hub of the other module so as to define the camshaft, on each hub there being provided means which cooperate with counter-means provided in each seat to torsionally lock said two modular elements together. According to the invention the camshaft comprises, between two consecutive cams, at least one annular element spaced from said cams and removably mounted on one of the two cylindrical elements of each module, said annular element comprising in its outer edge at least one recess so as to act as an additional cam, and comprising in its inner edge means for torsionally locking it to the cylindrical element on which said element or removable cam is mounted.
