    Abstract: A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. A first chamber is formed between the resonance plate and the piezoelectric actuator. After a gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device includes a valve plate and a gas outlet plate. After the gas is transferred from the miniature fluid control device to the miniature valve device, the valve opening of the valve plate is correspondingly opened or closed and the gas is transferred in one direction. Consequently, a pressure-collecting operation or a pressure-releasing operation is selectively performed.

    Abstract: A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. The gas collecting plate has a length in a range between 6 mm and 18 mm and a width in a range between 6 mm and 18 mm. A gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is driven and after the gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. The miniature valve device comprises a valve plate and a gas outlet plate. The gas is transferred from the miniature fluid control device to the miniature valve device so as to perform pressure-collecting operation or pressure-releasing operation.

    Abstract: A piezoelectric actuator includes a suspension plate, a piezoelectric ceramic plate, an outer frame and a bracket. The suspension plate is permitted to undergo a curvy vibration from a middle portion to a periphery portion. The piezoelectric ceramic plate is attached on the suspension plate. When a voltage is applied to the piezoelectric ceramic plate, the suspension plate is driven to undergo the curvy vibration. The outer frame is arranged around the suspension plate. The bracket is connected between the suspension plate and the outer frame for elastically supporting the suspension plate, and includes an intermediate part formed in a vacant space between the suspension plate and the outer frame and in parallel with the outer frame and the suspension plate, a first connecting part arranged between the intermediate part and the suspension plate, and a second connecting part arranged between the intermediate part and the outer frame.
