Claims

[Scope of utility model registration request]

The high-pressure air source and the drive-side pressure chamber and the return-side pressure chamber of the cylinder are communicated via a supply/discharge switching valve that switches both chambers into communication between the high-pressure air source and the atmosphere, and the high-pressure air source and the drive-side pressure chamber A throttle for meter-in control of the drive stroke of the cylinder and a pressure accumulation tank for assisting the activation of the drive stroke are connected between the high pressure air source and the supply/discharge switching valve in the flow path between the supply/discharge switching valve and the supply/discharge switching valve. A control valve that controls the return stroke speed is connected between the drive side pressure chamber, and the control valve is connected to a check valve that prevents high pressure air from flowing out from the drive side pressure chamber, and a throttle that restricts the outflow. A synchronous cylinder drive device, characterized in that it is constructed by connecting in parallel an IJ and IJ-f valves that operate in response to pressure increase with respect to a drive-side pressure chamber and a drive-side pressure chamber.
