ABSTRACT:
In a mechanical device for changing the phase relationship between the engine shaft and a camshaft of an internal combustion engine, in which the phase change is achieved by a change in the angular position of a body kinematically connected to the engine shaft relative to that of a shaft kinematically connected to the camshaft by the movement of a piston and of an auxiliary annular element which are spaced apart axially and are interposed between the body and the shaft to which they are coupled by intermeshing teeth, a stop is provided for limiting the axial travel of the auxiliary annular element, advantageously stopping the piston owing to engagement in the teeth of the shaft and of the body.
