The control valve is disposed between the master cylinder and the wheel cylinder for controlling the brake pressure. The control valve comprises a differential piston which has a control force applied thereto and a valve which is controlled dependent on the movement of the differential piston. To achieve a very simple construction and a great variation of different control valve types employing largely identical elements, the control valve of the present invention includes a sleeve inserted into the housing bore and a screw-in cap to close the housing bore. Associated with the sleeve and the screw-in cap are spacer members to keep the sleeve in place. The differential piston is a stepped piston having an axial pressure medium channel with the end of this channel in the smaller diameter portion of the stepped piston cooperating with a valve closing member to provide the regulating valve. The smaller diameter portion of the stepped piston is guided in the sleeve and the larger diameter portion of the stepped piston is guided in a coaxial bore of the screw-in cap. |
