PURPOSE: A driving circuit of a pneumatic actuator is provided to save compression energy by recycling some of exhausted compressed gas. CONSTITUTION: A driving circuit of a pneumatic actuator (30) comprises a first solenoid valve (10), a second solenoid valve (20), the pneumatic actuator, and a power (40). The first solenoid valve has a compressed gas inlet. The second solenoid valve forms first and second passages with the first solenoid valve and is connected to the first solenoid valve. The pneumatic actuator is driven when being connected to the first and second passages. The power electrically connects the first and second solenoid valves. |
