Abstract
(EN)
A check valve for a brake system is disclosed. The check valve for a brake system according to an embodiment of the present invention comprises: a valve seat having an inner oil passage formed therein; an opening/closing member which opens/closes the inner oil passage of the valve seat; an elastic member which elastically supports the opening/closing member at one end thereof; a valve housing which supports the other end of the elastic member and is coupled to the valve seat; and a plunger which is received in the oil passage and moves according to fluid flows generated when the brake system is operated.
