    • A brake oil pressure control device including a main line system for a normal braking operation, and a subline system for antiskid control and acceleration slip control. The main line system connects a master cylinder to a wheel cylinder, and has a first valve which opens the main line for a normal braking operation, and closes the main line when an antiskid control or acceleration slip control is in effect. The subline system has an oil pump connected to the wheel cylinder through a subline having a second valve, which is controlled to open and close the subline for the antiskid control or acceleration slip control. Inlet and outlet ports are connected by a relief pipe having a third valve and a relief valve. The relief valve opens the relief pipe under pressure from the master cylinder when a discharge pressure from the oil pump is higher than the pressure at the master cylinder, to restrain the discharge pressure from the oil pump. The third valve opens the relief pipe for an antiskid control, and closes the relief pipe for an acceleration slip control.
    • 一种制动油压控制装置,包括用于正常制动操作的主线系统和用于防滑控制和加速滑移控制的副线系统。 主线系统将主缸连接到轮缸,并且具有第一阀,其打开主线以进行正常制动操作,并且当防滑控制或加速滑移控制有效时闭合主线。 分线系统具有通过具有第二阀的副线连接到轮缸的油泵,其被控制为打开和关闭用于防滑控制或加速滑移控制的副线。 入口和出口通过具有第三阀和安全阀的溢流管连接。 当来自油泵的排出压力高于主缸的压力时,安全阀在主缸的压力下打开释放管,以抑制来自油泵的排出压力。 第三个阀打开用于防滑控制的释放管,并且关闭用于加速滑移控制的释放管。
