The chamber is assembled with a core (25) that is provided with a housing (26) for the axis and for an articulation on a crank pin of a crankshaft. The core is displaced with respect to rod`s body. The chamber is assembled with stoppers (27) encircling faces of the chamber perpendicular to a longitudinal symmetry axis (21) of the rod and limiting movement of the core in the direction of the symmetry axis, where the stoppers are constituted by springs.
