    摘要： A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having first and second ports, a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a first chamber when the piston is moving in a first direction to provide fluid flow out of the first port. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of the second port. The first and second ports are selectively in fluid communication with the wheel brakes.

    摘要翻译： 制动系统包括第一和第二车轮制动器，储存器和制动踏板单元，该制动踏板单元具有壳体和可滑动地设置在壳体中的一对输出活塞。 输出活塞在用于致动第一和第二车轮制动器的手动直通模式期间产生制动器致动压力。 该系统还包括柱塞组件，该柱塞组件具有具有第一端口和第二端口的壳体，驱动致动器的电机以及连接到致动器的活塞。 当活塞沿第一方向移动时，活塞对第一腔室加压以提供流体流出第一端口。 当活塞沿与第一方向相反的第二方向移动时，活塞对第二腔室加压，以提供流体流出第二端口。 第一和第二端口选择性地与车轮制动器流体连通。

    摘要： A pump-less brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons are operable during a manual push-through mode such that the pair of output pistons are movable to generate brake actuating pressure at first and second outputs for actuating the first and second wheel brakes, respectively. The system further includes a plunger assembly having a housing having first and second ports, a motor driving an actuator, and a piston connected to the actuator. The piston is slidably mounted within the housing. The piston pressurizes a first chamber when the piston is moving in a first direction to provide fluid flow out of the first port. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of the second port. The first and second ports are selectively in fluid communication with the first and second wheel brakes for actuation of the first and second wheel brakes from pressurized fluid within the first and second chambers. Fluid may flow from the first and second wheel brakes into the first chamber when the piston moves in the second direction.

    摘要： A vehicular hydraulic braking pump includes a sleeve having an inner bore defining an inner bore surface and a piston having a stop collar and a ramped seal face. The stop collar, ramped seal face, and the inner bore cooperating to define a seal pocket which traps a high pressure seal therein. The ramped seal face provides contact of the high pressure seal to the sleeve inner bore that is proportional to fluid pressure acting on the high pressure seal.
