Plural circuit brake system

Abstract

Abstract 1. Multiple-circuit brake system, especially for motor vehicles, with a multiple-circuit brake-power transmitter (7) which monitors at least one brake circuit (I) controllable by a pressure medium and an electrically controllable brake circuit (II) for brake actuation, and with brake cylinders (23, 24, 29, 30) following the brake-power transmitter (7), in one (I) of the brake circuit (I, II) there being a first pressure-control valve (19) which can be controlled both via the pressure medium and via the electrical system and to which is assigned a pressure-medium reservoir (5) for supplying control energy, and there being inserted into an electrical control line (11, 15, 16), leading from the brake-power transmitter (7) both to the said first pressure-control valve (19) and to a further second pressure-control valve (20) assigned to the other brake circuit (II), at least one switch element (12, 13, 14) which can be influenced by sensors (13', 14') sensing the driving state, characterized in that the second pressure-control valve (20) provided in the other (II) of the two brake circuits (I, II) can be actuated purely electrically.
