ABSTRACT:
In general pressure regulators for motor vehicle brake systems are arranged in the pressure medium line between the master brake cylinder and at least one wheel brake cylinder. The pressure regulator comprises a plunger valve with different pressure surfaces, which above a certain pressure level, reduce the brake pressure of the rear axle compared to the brake pressure of the front axle. In order to achieve a high reliableness and a simple construction of the pressure regulator, a non-return valve in the form of a sealing lip movable by a movable part of the plunger valve is provided. The sealing lip extends into the inlet chamber when the plunger valve is closed and closes a channel which leads through the valve plunger and/or valve body to the outlet chamber.
