摘要： An electronically controllable brake actuation system for motor vehicles is proposed, with a master brake cylinder (2), with a pressureless pressure medium reservoir (3), with a pressure source (20) which can be controlled by means of an electronic control unit (32), by means of which pressure can be applied to the wheel brakes (7, 8, 9, 10) of the vehicle, which can be connected by means of at least one hydraulic connection (11, 14), which can be shut off by means of a separating valve (12, 15), to the master brake cylinder (2), with a device (13, 33) for the recognition of the driver's wish to slow down, and with at least one separating piston arrangement (16) which is connected before the wheel brakes (7-10), where the first chamber (17) of this separating piston arrangement can be connected to the master brake cylinder (2), and its second chamber (19) can be connected through a valve device (27) to the pressure source (20) or to the pressure medium reservoir (3). In order to improve the ability to control the brake pressure of such a system, the proposal is made according to the invention that the valve device (27) be designed as a multiple position valve of the slide type, and that a switching seat valve (29) be inserted in the connection between the multiple position valve (27) and the pressure source (20).

摘要： The present invention discloses a magnetic valve for liquid and gaseous working media, in particular for hydraulic brake systems in automotive vehicles, which includes a first cylindrical housing part that is encompassed on its outside by a magnetic coil and has a cylindrical recess inside which extends in an axial direction to accommodate and guide an axmature, a tappet which is displaceable by the armature in an axial direction in opposition to a resetting spring, a second cylindrical housing part which is arranged coaxially to the first housing part and includes a cylindrical recess extending in an axial direction, the said recess being in connection to outside valve ports and in which a valve seat cooperating with the tappet is arranged. According to the present invention, the first and second housing parts form a housing which is made in one piece of a ferromagnetic material and encompasses the armature over at least part of its longitudinal extension in the shape of a sleeve whose walls are sufficiently thick to reduce the magnetic short-circuit but are not thicker than required to reliably accommodate mechanical stresses.
