A known hydraulic vehicle brake system has an anti-skid valve assembly. By this assembly, the at least one wheel brake can be temporarily disconnected from the master brake cylinder and connected to one inlet of a return pump, which furnishes the quantities of pressure fluid flowing out of the wheel brakes both to a damper chamber and, via a damper throttle, to the master brake cylinder and/or the at least one wheel brake. The disadvantage is that all of the pressure fluid pumped by the return pump can sometimes reach the master brake cylinder, disagreeably moving the brake pedal in the direction of its outset position. This can annoy a driver and should be avoided. The improved vehicle brake system has a valve, which in anti-skid operation can be blocked, located between the damper throttle and the master brake cylinder and also has a bypass throttle bypassing the valve. As a result, during anti-skid operation, the brake pedal is not displaced to such an annoying extent.

Hydraulic vehicle brake system with anti-skid apparatus

A vehicle brake system having a pump drivable via pressure from the master brake cylinder, a reservoir fillable by this pump, and an electrically controllable valve which, in traction control operation, pressure fluid from the reservoir can be delivered to an inlet of the return pump. Via the pressure fluid from the reservoir, this return pump generates pressure for the wheel brakes of the drivable wheels.
