Title:
GAS TRANSPORTATION DEVICE
Document Type and Number:
Japanese Patent JP2019052643
Kind Code:
A
Abstract:
To provide a gas transportation device which controls gas into flow in a single direction, accumulates the gas in a chamber of limited volume or a flow passage, and can raise a gas transportation quantity.SOLUTION: A gas transportation device 1 laminates an entrance plate 17, a base material 11, a resonance plate 13, an actuator board 14, a piezoelectric unit 15, and an outlet plate 16 in order, further contains at least one valve 10. The valve 10 is installed at least either in an inlet hole 170 or an outlet hole 160, and provided with a confluent chamber 12, a first chamber 18, and a second chamber 19. When the piezoelectric unit 15 drives the actuator board 14, the first chamber 18 and the second chamber 19 form pressure difference. Then, the valve 10 is opened, the gas enters the confluent chamber 12 through the inlet hole 170, enters the first chamber 18 via a hollow hole of the resonance plate 13, is introduced into the second chamber 19 through a gap of the actuator board 14, and is finally let out of the outlet hole 160.SELECTED DRAWING: Figure 1
