    • A braking system includes a brake actuator which is moveable in a first direction to cause a brake applying member to apply a braking force to a member to be braked. A master valve includes a piston assembly which upon operation of a brake operating member, directs the hydraulic fluid under pressure to the brake actuator to apply the brake. A charging valve is operable in first and second states. The master valve piston assembly includes a pair of coupled pistons separated by a chamber. In a first state, the charging valve connects a source of pressurized hydraulic fluid to the master valve chamber to move the pistons apart, directing a volume of hydraulic fluid to the brake actuator. In a second state, the charging valve connects the chamber to a lower pressure area to allow the pair of pistons to be moved towards one another by a restoring force.
    • 制动系统包括制动器致动器,该致动器可沿第一方向移动,以使制动施加部件向要制动的部件施加制动力。 主阀包括活塞组件,其在制动操作构件的操作时将压力下的液压流体引导到制动器致动器以施加制动。 充气阀可在第一和第二状态下操作。 主阀活塞组件包括一对由腔室隔开的联接活塞。 在第一状态下,充气阀将加压液压流体源连接到主阀室以使活塞间隔开,将一定体积的液压流体引导到制动致动器。 在第二状态下,充气阀将腔室连接到较低压力区域,以允许一对活塞通过恢复力彼此相对移动。

    • A differential master cylinder includes a hollow primary piston (12) and a hollow secondary piston (13) with different diameters, which are open at least at one end and are mutually associated in telescopic manner so that the primary piston (12) slides on the secondary piston (13), which is stationary, and so that their internal cavities communicate with each other to form a single chamber (15) connected to a user device. The pistons (12, 13) also define, with internal surfaces of a bore (11) housing both pistons, at least one external annular chamber (16) cooperating with the internal chamber during an initial phase of the operation. The invention also relates to a braking system for a motor vehicle comprising the differential master cylinder and to a method of driving a user device with fluid under pressure by means of the cylinder.
