Fluid system

A fluid system produced by an integrated process, comprising:

• at least one fluid active region comprising:
• at least one fluid-guiding unit enabled to transport fluid;
• and
• at least one outlet aperture through which the fluid is discharged out;
• at least one fluid channel in communication with the at least one outlet aperture of the fluid active region, the fluid channel comprising plural branch channels for splitting the fluid discharged from the fluid active region to achieve a required amount of the fluid to be transported;
• at least one convergence chamber in fluid communication with the fluid channel for allowing the fluid to be accumulated in the convergence chamber;
• a plurality of valves each of which is disposed in the corresponding branch channel, wherein the fluid transported through the corresponding branch channel is controlled by an open/closed state of the valve disposed therein, and each of the valves comprises:
• at least one base comprising at least one first passage and at least one second passage separated from each other, the first passage and the second passage being in communication with the corresponding branch channel, wherein at least one cavity is concavely formed on a surface of the base, and the cavity comprises at least one first outlet in communication with the first passage and at least one second outlet in communication with the second passage;
• at least one piezoelectric actuator comprising:
• at least one carrier plate covering and closing the cavity;
• and at least one piezoelectric ceramic plate attached on a first surface of the carrier plate;
• and
• at least one linking bar having a first end and a second end, the first end of the linking bar being connected to a second surface of the carrier plate, the linking bar being inserted into the second outlet and movable within the second outlet, wherein at least one stopping part is formed at the second end of the linking bar and has a cross section area with a diameter larger than a diameter of the second outlet for closing the second outlet,
• wherein when the piezoelectric actuator is enabled, the carrier plate is driven to move, and the stopping part of the linking bar is correspondingly moved to selectively close or open the second outlet, so that the fluid is selectively transported through the corresponding branch channel.
