    • A pump attenuator bypass valve (40/100/200) is located at an outlet of a pump (30) in a vehicle braking system (10) between the pump (30) and an attenuator (34). The attenuator bypass valve (40/100/200) includes a bypass valve housing (41), a first fluid flow path (74, 57/179/220, 208), and a second fluid flow path (80/183). The first fluid flow path (74, 57/179/220, 208) is defined in the housing (41) and is configured to allow continuous flow of fluid when the pump (30) operates at a first pump flow rate. The second fluid flow path (80/183) is defined in the housing (41) and is configured to bypass the first fluid flow path (74, 57/179/220, 208) and to allow continuous flow of fluid when the pump (30) operates at a second pump flow rate higher than the first pump flow rate.
    • 泵衰减器旁通阀(40/100/200)位于泵(30)和衰减器(34)之间的车辆制动系统(10)中的泵(30)的出口处。 衰减器旁通阀(40/100/200)包括旁通阀壳体(41),第一流体流路(74,57 / 179 / 208,208)和第二流体流路(80/183)。 第一流体流动路径(74,57 / 179 / 208,208)限定在壳体(41)中,并且构造成当泵(30)以第一泵流量运行时允许流体的连续流动。 第二流体流动路径(80/183)限定在壳体(41)中,并且构造成绕过第一流体流动路径(74,57 / 179 / 208,208),并且当泵( 30)以比第一泵流量高的第二泵流量运行。

    • 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.
    • 制动系统包括第一和第二轮子制动器,储存器和制动踏板单元,其具有可滑动地设置在壳体中的壳体和一对输出活塞。 输出活塞在手动推直模式下产生制动器致动压力,用于致动第一和第二轮制动器。 该系统还包括具有壳体的柱塞组件,该壳体具有第一和第二端口,驱动致动器的马达和连接到致动器的活塞。 当活塞沿第一方向移动时,活塞对第一室施压,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轮式制动器流体连通。

    • A brake system includes first and second wheel brakes and a brake pedal unit including a housing and a pair of output pistons slidably disposed in the housing, 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, during a manual push through mode. A plunger assembly for actuating the first and second wheel brakes during a normal brake apply includes a housing and a motor mounted on the housing for driving an actuator. A first piston is connected to the actuator. The first piston is slidably mounted within the housing for pressurizing a first fluid chamber in the housing. The first fluid chamber is in communication with the first wheel brake. A second piston is slidably mounted within the housing for pressurizing a second fluid chamber in the housing. The second fluid chamber is in communication with the second wheel brake. A pump-less control valve arrangement includes a first control valve regulating the flow of fluid between the first fluid chamber and the first wheel brake. A second control valve regulates the flow of fluid between the second fluid chamber and the second wheel brake. An isolation valve arrangement switches the brake system between the normal braking mode wherein boost pressure from the plunger assembly is supplied to the wheel brakes, and the manual push-through mode wherein brake actuating pressure from the brake pedal unit is supplied to the wheel brakes.
