Date May 27, 1993.A pressure modulator for a hydraulic brake system having a first cylinder bore with a servo piston, a second cylinder bore with a control piston, and a guide bore connecting the first cylinder bore to the second cylinder bore, in which a control tappet is disposed in a guide bore. An exact guidance of the servo piston in the first cylinder bore of the pressure modulator is assured. A control tappet is arranged, in the guide bore and the servo piston, on an end toward the control tappet, has a tappet extension that protrudes into the guide bore of the housing. In this way, exact guidance of the servo piston is assured. The novel pressure modulator is especially suitable for hydraulic brake systems of motor vehicles.
