    • An improved brake hydraulic pressure generating device is provided in which the hydraulic pressure supplied from a hydraulic pressure source is adjusted to a value corresponding to the brake operating force by means of a pressure adjusting valve which is activated according to displacement of an input piston or a simulator piston, and while the device is normal, a master cylinder is activated by the output hydraulic pressure. If the hydraulic pressure source or a hydraulic line connecting thereto fails, a sufficient braking force is ensured with a short stroke. There are provided a shutoff valve which shuts off communication between the simulator chamber and the atmospheric reservoir when the stroke of the input piston has exceeded a predetermined value, and a check valve which permits the flow of fluid from the atmospheric reservoir to the simulator chamber. This suppresses an unavailable stroke of the simulator piston without impairing the return of the simulator piston.
    • 提供了一种改进的制动液压发生装置,其中从液压源供应的液压压力通过压力调节阀调节到与制动器操作力相对应的值,压力调节阀根据输入活塞或 模拟活塞,当设备正常时,主缸由输出液压启动。 如果液压源或与其连接的液压管线失效,则以短行程确保足够的制动力。 提供了一种截止阀,当输入活塞的行程超过预定值时,切断模拟器室和大气储存器之间的连通,以及允许流体从大气储存器流动到模拟器室的止回阀。 这抑制了模拟器活塞的不可用行程,而不损害模拟器活塞的返回。

    • A tandem pneumatic booster includes a front shell having a relatively long cylindrical portion and a rear shell having a relatively short cylindrical portion. The cylindrical portions of the front and rear shells are joined together to form a shell body. An opening edge of a cylindrical portion of a center shell is disposed in the joint between the front and rear shells, together with an outer peripheral bead of a diaphragm of a rear power piston. The cylindrical portion of each of the front, rear and center shells has a frusto-conical shape gradually increasing in diameter toward the opening edge thereof. Thus, when front shells, rear shells and center shells are stacked on one another, respectively, as constituent parts before assembly, the depth of fitting between each pair of adjacent shell elements is increased sufficiently to stably maintain the stacked conditions of the shell elements.

    • A vehicle motion control device reduces noise resulting from operation of a vacuum booster when an automatic pressure control is performed by properly controlling the energization of a linear solenoid of a booster actuator. An automatic hydraulic pressure generator is controlled in accordance with the vehicle motion condition and a hydraulic pressure control valve device is controlled to perform the automatic pressure control. A target electric current of the linear solenoid for actuating the vacuum booster is instantaneously increased to a starting target value which corresponds to an electric current value immediately before starting the operation of the vacuum booster and which is less than a maximum value of the target electric current, and then is gradually increased approximately to the maximum value of the target electric current.
