Claims

[Scope of utility model registration request]

The position of the load driven by a double-acting pneumatic cylinder is fed back, and a control signal corresponding to the error between it and the target stop position is applied from the electric control circuit to the electro-pneumatic proportional control valve to connect it to the control valve. In the above-mentioned pneumatic syringe, the control valve for supplying and discharging pressurized air to and from the head chamber and the rod chamber in the upper double-acting pneumatic cylinder and the cylinder is connected to each port when the solenoid is de-energized. A cylinder control device configured as a center-closed five-port valve in which a flow path between the two is blocked.
