Abstract
A control arrangement of a hydraulic vehicle braking system provided with antiskid control equipment includes a master cylinder device which is actuatable by a brake pedal and is provided with at least one master piston cooperating with an associated replenishment chamber. The replenishment chamber is hydraulically connected through a substantially radial bore with the secondary side of the master piston. An axially displaceable circumferentially sealed positioning piston is disposed at the secondary side of the master piston, and a piston rod of the master piston concentrically and sealingly passes through the positioning piston. The piston rod of the master piston is provided, at its free end which is closer to the brake pedal, with an enlarged circumferential projection which can be brought in engagement with an associated circumferential edge of the positioning piston upon depression of the brake pedal and after admission of the pressurized hydraulic fluid from the auxiliary energy source to the secondary side of the master piston in such a manner that the master piston is moved into a defined position during antiskid control operation. Alternatively, this engagement of the positioning piston can take place with a circumferential projection of a throttling valve which is interposed between the brake pedal and the master cylinder device.
