  • INJECTION DEVICE AND MOLDING MACHINE
    Publication number: 20220168937
    Abstract: A run-around circuit makes a hydraulic fluid discharged from a rod-side chamber along with a forward movement of a piston in an injection cylinder flow into a head-side chamber. A servo valve is provided in the run-around circuit and is connected to a tank. In a first state, the servo valve permits flow from the rod-side chamber to the head-side chamber, while prohibits flow from the rod-side chamber to the tank. In a second state, the servo valve prohibits flow from the rod-side chamber to the head-side chamber, while permits flow from the rod-side chamber to the tank. The servo valve can control the flow rate of the hydraulic fluid discharged from the rod-side chamber in each of the first state and second state.
