Abstract
The present invention relates an antiskid apparatus for an automotive vehicle. The apparatus includes a cut-off valve which is connected between a master cylinder and a wheel cylinder and provides communication therebetween in response to wheel cylinder pressure and cuts off pressurized hydraulic fluid from the master cylinder when an antiskid operation is performed by the control system. A solenoid valve is positioned in a conduit which connects the wheel cylinder to the cut-off valve. The solenoid valve is also connected to a discharge side of a pump which circulates pressurized oil. When the solenoid is in a normal position, the wheel cylinder is connected to the cut-off valve in the discharge side of the pump. When changed over from the normal position, the solenoid valve disconnects the wheel cylinder from the cut-off valve and the discharge side of the pump and connects the wheel cylinder to a reservoir connected to an intake side of the pump.
