Abstract
The electromagnetic valve is comprised of first communication path and second communication path with a throttle connected in parallel to each other, a first plunger having a first valve for interrupting/communicating the first communication path and having a penetration hole extending to the second communication path, a second plunger having a second valve movable in or through the penetration hole for interrupting/communicating the second communication path, a spring member for generating spring biasing force and a coil member for generating an electromagnetic attracting force, when energized, to have the first and second plungers come close to each other against the spring biasing force. The electromagnetic valve may be controlled in a manner that the first communication path is interrupted and the second communication path is communicated at a pressure-increase timing during an anti-skid control.
