A rotary machine such as a pump, compressor or internal combustion engine comprises blades or pistons pivotally mounted on a rotor for cooperation with an inner cylindrical wall of a stator. A mechanism controlling the angular position of the blades or pistons comprises one or more connecting rods pivoted at one end on an axle of the stator eccentric to the rotor axis and at another end on a lever fixed for pivoting with the corresponding blade(s) or piston(s). For a machine with blades, this control mechanism is housed in a lateral cover on the stator, and for a machine with pistons, it is disposed within the rotor.
