    • The invention relates to an electronically adjustable brake actuation system for motor vehicles, comprising a master cylinder (2) with a pressureless hydraulic fluid tank (3), a pressure source (20) which can be controlled by an electronic control unit (32) enabling pressure to be exerted upon the wheel brakes (7, 8, 9, 10) of the motor vehicle. Said brakes can be joined to the master cylinder (2) by at least one hydraulic connection (11, 14) which can be shut off by a block valve (12, 15). The invention is also provided with a device (13, 33) for detecting the driver's desire to decelerate, in addition to at least one separating piston (16) arranged upstream from the wheel brakes (7-10) and whose first chamber (17) can be connected to the master cylinder (2) and whose second chamber 919) can be connected to the pressure source (20) or the hydraulic fluid tank (3) by a valve device (27, 271). In order to improve the dosing of braking pressure in said system, the invention provides that the valve device (27, 271) is formed by a multiposition valve built like a gate valve, and that a switching seat valve (29) is inserted in the joint between the multiposition valve (27, 271) and the pressure source (20).
    • 本发明涉及一种用于机动车辆的可电子调节的制动器致动系统,该系统包括具有无压力液压流体箱(3)的主缸(2),可由电子控制单元(32)控制的压力源(20) 压力施加在机动车辆的车轮制动器(7,8,9,10)上。 所述制动器可以通过至少一个液压连接件(11,14)连接到主缸(2),所述液压连接件可以通过截止阀(12,15)关闭。 除了布置在车轮制动器(7-10)上游的至少一个分离活塞(16)以及其第一腔室(17)之外,本发明还设有用于检测驾驶员减速的愿望的装置(13,33) 可连接至主缸(2),并且其第二腔室919)可通过阀装置(27,271)连接至压力源(20)或液压流体箱(3)。 为了改进所述系统中的制动压力的配量,本发明规定,所述阀装置(27,271)由构建为类似闸阀的多位置阀形成,并且切换座阀(29)插入所述系统 多位阀(27,271)和压力源(20)之间的接头。
