Abstract

A fluid transportation device (20) includes a valve seat (21), a valve cap (22), a valve membrane (23), multiple buffer chambers (223, 215), a vibration film (241) and an actuator (242). The valve membrane (23) is arranged between the valve seat (21) and the valve cap (22), and includes several hollow-types valve switches (231, 232), which includes at least a first valve switch (231) and a second valve switch (232). The multiple buffer chambers (223, 215) include a first buffer chamber (223) between the valve membrane (23) and the valve cap (22) and a second buffer chamber (215) between the valve membrane (23) and the valve seat (21). The vibration film (241) is separated from the valve cap (22) when the fluid transportation device (20) is in a non-actuation status, thereby defining a pressure cavity (226). The actuator (242) is connected to the vibration film (241). When the actuator (242) is driven to be subject to deformation, the vibration film (241) connected to the actuator (242) is transmitted to render a volume change of the pressure cavity (226) and result in a pressure difference for moving the fluid.
