The subject of the invention is a universal method and a device for supporting the process of press moulding of finely fragmented materials by means of mechanical vibrations. The device comprises a motor driving, via a belt transmission, the flow pulse generator (3) connected permanently with actuator. The feeding for flow pulse generator (3) is supplied to port (6), and the outflow to the reservoir occurs via port (7). On the circumference of rotor (17) of the flow pulse generator (3), a plurality of grooves is made. Groove (10), on one side, is connected permanently with passage of port (6), and on the other side, depending on position of rotor (17), it can be connected with arms of the flow guide. Groove (9), on one side, is connected permanently with passage of port (7), and on the other side, depending on position of rotor (17), it can be connected with arms of the flow guide. Passage (12) depending on position of rotor (17), is connected directly with groove (8) or with groove (9). Passage (12) is connected with space (13) above the actuator piston. Passage (14), depending on position of rotor (17), is connected directly with groove (10) or with groove (11). Passage (14) is connected with space (16) under the actuator piston (5). Grooves (8) and (9) are separated from grooves (10) and (11). The unit generating mechanical vibrations is characterised with low flow resistance and high tightness which ensures high energy efficiency and low level of noise emitted by the device.
