Beschreibung
Zusammenfassung:	An injection device of a die casting machine including an injecting cylinder, in which a piston connecting to a piston rod is slidably thrust into a cylinder body and in which pressurized oil is fed to the side of the piston from a pressurized oil source and flows out from the side of the piston rod, and a servo valve controlling an injection speed of the injection cylinder device by controlling the amount of flow of pressurized oil that flows out from the injecting cylinder. The servo valve is directly attached to the cylinder body of the injecting cylinder and a flow channel connecting the injecting cylinder and servo valve is shortened.
