Title: Hydraulic brake system for motor vehicles

Abstract: The brake system has at least one brake circuit (I), in which a high-pressure pump is disposed. A self-aspirating charge pump is also provided, which is connected at least indirectly to the intake side of the high-pressure pump by an intake line of a supply container for brake fluid and by a pressure line. In the event of an inadequate supply of brake fluid by the charge pump, the pumping of air into the brake circuit (I) is intended to be precluded. To that end, a siphon is disposed in the intake line of the charge pump. Air aspirated by the siphon suddenly prevents pumping by the charge pump. The brake system is intended for use in motor vehicles with slip control or for automatic brakes.
