    • Known vacuum brake boosters are provided with a heavy sheet metal vacuum housing for transmitting reaction forces of the mechanical actuation to the booster carrier plate secured to a vehicle. According to the present invention the weight of the booster is remarkably reduced by providing draw bars for transmitting the reaction forces to the carrier plate inside the vacuum housing parallel to the push rod, penetrating the vacuum piston or movable wall and connecting both transverse end walls of the vacuum housing to the carrier plate. The draw bars are sealed at their point of penetration of the vacuum piston by small rolling membranes which are surrounded by tubular members fastened to the vacuum piston. A base plate assembly is provided including a base plate fastened to the transverse end wall of the vacuum housing adjacent the master cylinder, bolts fastened to one side of the base plate upon which the master cylinder is fastened and the draw bars are fastened to the other side of the base plate.

    • A master cylinder device for controlling the pressure of hydraulic braking fluid in two separate braking circuits of a hydraulic braking system includes a housing having two parallel and co-extensive pressure chambers each movably accommodating one master piston. A pressure element transmits the brake pedal force to one of the master pistons to pressurize the fluid present in a first pressure compartment and thus in the associated first brake circuit. A part of the thus pressurized fluid is diverted to an actuating compartment of the other pressure chamber to act on the other master piston and thus to pressurize the fluid present in the second pressure compartment and in the associated other brake circuit. When elevated pressure fails to develop in the first pressure compartment, the pressure element engages a tappet of the other master piston to mechanically displace the same in the actuating direction and thus to pressurize the fluid supplied to the other brake circuit. A brake booster may be connected to the housing of the master cylinder device and act on the pressure element to boost the actuating force acting on the pressure element.
    • 用于控制液压制动系统的两个分离的制动回路中的液压制动流体的压力的主缸装置包括具有两个平行和共同压力室的壳体,每个压力室可移动地容纳一个主活塞。 压力元件将制动踏板力传递到主活塞中的一个以对第一压力室中存在的流体加压,并且因此在相关联的第一制动回路中加压。 这样加压的流体的一部分被转移到另一个压力室的致动室,以作用在另一个主活塞上,并且因此对存在于第二压力室中的流体和相关联的其它制动回路加压。 当在第一压力室中升高的压力不能发展时,压力元件接合另一个主活塞的挺杆,以使其在致动方向上机械地移动,从而对供应到另一制动回路的流体加压。 制动助力器可以连接到主缸装置的壳体并且作用在压力元件上以增加作用在压力元件上的致动力。

    • In prior art vacuum brake boosters embodying a two-stage reaction, the magnitude of the two-stage reaction is limited because of the small space available for the reaction-delaying spring. Moreover, the lost motion present in the reaction lever mechanism has to be overcome when the braking operation is initiated. These disadvantages are overcome in a vacuum brake booster including a reaction mechanism constructed in accordance with the present invention wherein the reaction-delaying spring is positioned on the side of the reaction levers adjacent the vacuum chamber and by having the point of contact of the spring on the reaction levers at a greater radius than the point at which the levers are in engagement with the movable wall.
    • 在现有技术中体现两级反应的真空制动助力器中,由于反应延迟弹簧的可用空间小,两级反应的大小受到限制。 此外,当制动操作开始时,必须克服反作用杆机构中存在的空动。 在包括根据本发明构造的反作用机构的真空制动助力器中克服了这些缺点,其中反作用延迟弹簧位于靠近真空室的反作用杆的侧面上,并且通过使弹簧的接触点 该反作用杆的杠杆比可操作的壁处于更大的半径处。

    • A brake booster comprising a housing which is divided into a vacuum chamber and a working chamber by a movable wall. A tube is disposed in the housing coaxial of the longitudinal axis thereof having its ends fastened to the end walls of the housing. The tube is provided with longitudinal slots in the vacuum chamber which are open remote from the movable wall. Parts of the movable wall project through the slots and are fastened to a valve housing extending into the tube, the valve housing containing a control valve which controls the pressure in the working chamber. This arrangement allows a short overall length of the booster and enables easy assembly thereof with respect to known prior art brake boosters.
