The invention provides a redundant brake unit and a brake system. A redundant brake unit for a motor vehicle includes an inlet port configured to receive a fluid under pressure from an external source; an outlet port connected to the supply channel and configured for fluid connection to a wheel brake; a reservoir port connected to the return passage and configured for fluid connection to a fluid reservoir; a pressure increasing valve configured to selectively control fluid communication between the inlet port and the supply passage; and a pressure supply unit including a pump element configured to pump fluid between the return passage and the supply passage. The pump element has an inlet directly connected to the reservoir port with no actuation valve between the inlet and the reservoir port. A normally closed valve and a throttle valve are disposed in a series configuration between the supply passage and the return passage, the throttle valve being operable to control fluid pressure in the supply passage.

    本公开提供了一种冗余制动单元及制动系统。一种用于机动车辆的冗余制动单元包括:入口端口,其被配置为从外部源接收处于压力下的流体;出口端口,其连接到供应通道并且被配置用于流体连接到车轮制动部;储存部端口,其连接到回流通道并且被配置用于流体连接到流体储存部;增压阀,其被配置为选择性地控制入口端口与供应通道之间的流体连通;以及压力供应单元,其包括泵元件,泵元件被配置为在回流通道与供应通道之间泵送流体。泵元件具有直接连接到储存部端口的入口,在入口与储存部端口之间没有致动阀。常闭阀和节流阀在供应通道与回流通道之间以串联配置设置,节流阀可操作以控制供应通道中的流体压力。
