Abstract
An electromagnetic valve is arranged in a conduit between a master cylinder and an intake side of a pump in a brake control system. In the electromagnetic valve, a main communication path and a restricted communication path are formed. The main communication path is alternatively opened and closed by a main valve body. The restricted communication path is formed in the main valve body and alternatively opened and closed by an auxiliary valve body. A solenoid generates electromagnetic force to bias the auxiliary valve body in a direction of opening the restricted communication path. The auxiliary valve body is provided with an engaging portion for engaging with the main valve body to move the main valve body in a direction of opening the main communication path after opening the restricted communication path.
