摘要:
A light-weight pneumatic massage apparatus with low operation noise is provided. This apparatus includes a pneumatic massage device and a pump separated from the massage device. The apparatus further includes electromagnetic valves for controlling supply and discharge of pressurized air to and from air chambers of the pneumatic massage device, respectively. Each of the electromagnetic valves includes a displaceable valve member having an armature, and a solenoid for attracting the armature to move the displaceable valve member when a voltage is applied to the solenoid. The apparatus further includes an electromagnetic valve control unit which controls a voltage supplied to the solenoid to open the electromagnetic valves such that the voltage increases from gradually with the passage of time. The armature is attracted onto the end surface of the solenoid within the time period. Then, in a state in which the voltage is reduced to, the armature is maintained attracted onto the solenoid to keep the open state. After that, voltage supply is stopped to close the valve.
