Abstract

The present invention relates to a hydraulic device for the synchronization of two interacting hydraulic pistons, preferably at least two counter-impacting pistons for moulding at a high kinetic energy, comprising at least one first hydraulic piston (400) and at least one second hydraulic piston (500), respectively; at least one first (410) and at least one second (510) hydraulic cylinder, respectively; a pressing portion/impact portion (501 and 401, respectively) arranged to each hydraulic piston; a return surface (402 and 502, respectively); and a working surface (403 and 503, respectively); a return chamber (411 and 511 respectively) and a working chamber (412 and 512, respectively) provided in each cylinder; a hydraulic conduit (420, 430, 520, 530) connected to each chamber 411, 412, 511, 512); and at least one valve device (1) for controlling the flow of oil to at least one of said conduits to synchronize the movements of the hydraulic pistons (400, 500).
