Abstract

A simulator valve and an electronic brake system using the same are disclosed. The electronic brake system includes a master cylinder provided with at least one cylinder chamber having a volume changeable according to operation of a pedal, a pedal simulator connected to the cylinder chamber, configured to provide reaction force corresponding to a pedal effort of the pedal, a hydraulic-pressure supply device configured to provide hydraulic pressure to at least one wheel cylinder, an electronic control unit (ECU) configured to operate the hydraulic-pressure supply device, and a simulator valve provided in a flow passage through which the master cylinder is connected to the pedal simulator, and provided with a unidirectional flow passage that allows fluid to flow from the pedal simulator to the cylinder chamber and a bidirectional flow passage that is electronically opened or closed.
