1. A device for converting a rotational motion into a rectilinear reciprocating motion, and vice versa, in particular for the use in volumetric internal combustion engines, and in compressors, characterized in that it comprises: only one auxiliary crank (4) and only one rotor (30) containing the axis of rotation of the auxiliary crank (4), which are both arranged on only one side of the auxiliary crank pin (15); means (1, 3) which impose to the auxiliary crank (4) and to the rotor (30) rotational motions such that when the auxiliary crank (4) performs a rotation in one direction, said rotor (30) rotates by half that angle and in the opposite direction; said means (1, 3) comprising a planet wheel (3) integral with said auxiliary crank (4) and which is located between two supports arranged inside the rotor (30), and a ring gear (1) with internal toothing, integral with a housing (7); said rotor (30) being monolithic and located inside the housing (7); the pitch circle diameter of the planet wheel (3) being equal to half the pitch circle diameter of the ring gear with internal toothing; and the input or drawing of power being performed by means of a shaft (16) which is integral with the rotor (30) and rotates with it. 2. A device according to claim 1, wherein the device can be used for the construction of machines comprising several devices of the same kind, which are synchronised with respect to each other by means of a shaft simultaneously engaging the rotor (30) of each of said devices; the axis of said shaft being arranged so as to not hinder the rectilinear reciprocating motions of the connecting rod pin (15) of each device. 3. A device according to claim 2, wherein said shaft, besides performing the synchronisation of the various devices, also collects the torque of each device, and outputs them at a single power take-off.
