ABSTRACT:
A valve (actuator) for performing pressurization, decompression and pressure maintenance drives plural spools movable up and down within a housing having plural bores by using linear shape memory alloys, and an anti-lock brake system utilizes the valve, in which respective bores have inlets and outlets, a mechanism for holding a lowering state of the spools is installed to the lower portion of the housing, and the spools return to their original positions by bias springs. A master cylinder, a wheel brake and a hydraulic pump are connected to the inlets and outlets of the valve of the anti-lock brake system and an electronic control unit is connected to the shape memory alloys to actuate the shape memory alloys, thereby attaining the operations of pressurization, decompression and pressure maintenance in connection with a brake pressure of the wheel brake.
