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.
