Abstract (en)
A miniature pneumatic device (1) includes a miniature fluid control device (1A) and a miniature valve device (1B). The miniature fluid control device (1A) includes a gas inlet plate (11), a resonance plate (12), a piezoelectric actuator (13) and a gas collecting plate (16). A first chamber (121) is formed between the resonance plate (12) and the piezoelectric actuator (13). After a gas is fed into the gas inlet plate (11), the gas is transferred to the first chamber (121) through the resonance plate (12) and then transferred. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device (1B) includes a valve film (17) and a gas outlet plate (18). After the gas is transferred from the miniature fluid control device (1A) to the miniature valve device (IB), the valve opening (170) of the valve film (17) 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.
