A hydraulic vehicle brake system, which has a brake pressure signal generator which can be activated by a brake activation device, wherein the brake pressure signal generator can be connected to wheel brakes of the vehicle via at least one hydraulic line and is composed essentially of a master brake cylinder and a hydraulic booster which is connected upstream and which has a return flow chamber and a boosting chamber, a working piston arranged therein and a control piston, wherein the working piston is operatively connected in the force outputting direction to a master brake cylinder piston via an activation element, and a hydraulic pressure of a hydraulic pressure source can be applied to the booster via an inlet for the purpose of boosting braking force, wherein an outlet of the booster can be connected to a reservoir vessel.

Hydraulic vehicle brake system and method for operating the hydraulic vehicle brake system

A control valve with a control slider (9) comprising bead-type areas (17, 18, 19), by means of which the control slider is slidably arranged in the cylinder bore (8). The areas (17) and (18) isolate the inlet (2) from the outlet (3), while the area (19) isolates the outlet (3) from the leakage oil port (4). The clearance between the areas (17) and (18) of the control slider (9) and the wall of the cylinder bore (8) is smaller than the clearance between the area (19) of the control slider (9) and the wall of the cylinder bore (8). The output pressure is kept within close tolerances with only minor leakage losses.
