Abstract
A gas transportation device is provided and includes an outer housing, a valve body and an actuator. The valve body includes a gas outlet plate, a valve plate and a first plate. The gas outlet plate includes plural outlet apertures, the first plate includes plural first orifices, the valve plate includes plural valve openings, the plural valve openings are misaligned with the plural first orifices and corresponding in position to the plural outlet apertures. The actuator having an actuating component in rectangular shape is stacked and disposed on the valve body. When the actuator is driven, through the structure that the plural first orifices and the plural valve openings are misaligned, the valve body is operated to open a flow path when an airflow is in a forward direction, and the valve body is operated to seal the flow path when the airflow is in a reverse direction.
