An electromechanical power converter for a gaseous or vaporous media, containing a stator (1) consisting of two cup-shaped stator parts (la, lb) which are respectively open in the direction of a front face and adjacent thereto. Said stator parts surround a working area (12) and form a common, magnetically through-flown gap (7) wherein a coreless armature coil (25) is displaceably arranged. A free-swinging piston (14) which is connected to the armature coil (25) is mounted in the working area (12). Also provided is at least one source (21a, 21b) for the medium, two reaction chambers (66a,66b) associated with the bases (15a, 15b) of the piston (14), in addition to control means (17a, 19a, 22a, 23a; 17b, 19b, 22b, 23b) associated with the reaction chambers (66a, 66b) for automatic control of the oscillations of the piston. Said control means are used to open the reaction chambers (66a, 66b) in the direction of the source (21a, 21b) during the oscillations of the piston in order to receive the pressurized medium and in the direction of the working chamber (12) in order to discharge the expanded medium.
