ABSTRACT:
Disclosed are a micro-actuator, a fabrication method thereof, and a micro-actuating valve. The micro-actuating valve comprises: a first valve housing having a fluid entrance at the middle portion thereof; a second valve housing coupled to the first valve housing thus to form a space portion therein and having a fluid exit connected to the fluid entrance of the first valve housing; a plate installed at the space portion and having a micro-channel at one side thereof to be connected to the fluid exit; a plurality of micro-driving members installed to be near the plate for discharging a fluid introduced from the fluid entrance of the first valve housing to the fluid exit of the second valve housing by selectively opening and closing the micro-channel of the plate; a micro-mover suspension installed at the plate for supporting the micro-mover; a coil installed at the micro-mover; a magnet installed with a certain gap from the coil; and an electrode portion formed at the plate for is supplying a power source to the coil.
