A device for regulating and stabilizing the pressing force in machines for the pressure casting of metals with hydraulic drive, consisting of a hydraulic cylinder and a high pressure hydraulic circuit, an investment valve being interposed in the high pressure pipe and a hydraulically adjustable pressure regulating valve, which regulates the subsequent pressure in the high-pressure pipe as a function of the back pressure in the hydraulic cylinder, characterized in that the vacuum regulating valve and the reversing valve are successively arranged in series between a pressure accumulator and a high-pressure pump on one side and the hydraulic cylinder on the other hand, and because the servo-piston drive of the pressure regulating valve is connected in a regulable manner to the high-pressure pipe.
