Abstract

The invention relates to a hydraulic motor vehicle power brake system having a hydraulic pump which is connected to a hydraulic reservoir as an external energy reservoir and is connected to wheel brake cylinders, wherein the wheel brake cylinders are preceded by inlet valves and are followed by outlet valves. To improve the adjustability of a desired brake pressure in the wheel brake cylinders and to cut costs, the inlet and outlet valves are identical as continuous pressure limiting solenoid valves or as continuous pressure differential solenoid valves.
