A brake valve (1) comprising a body (10), a shaft (20) movable within the body (10), a spool plate (60) movable between a release configuration and a braking configuration, the shaft (20) being adapted to be connected to a first actuator (70) configured to slide the shaft (20), and a first spring (40) and a second spring (50) arranged within the body (10), the spool plate (60) being adapted to be connected to a second actuator (70) configured to slide the shaft (20). The brake valve (1) comprises a command fluid port (90) connected to the brake chamber (92), a valve ring (95) defining the brake chamber (92) with the body (10) and the shaft (20), the valve ring (95) being configured to move the shaft (20) towards the actuated position or urge the second spring (50) to move the spool plate (60) towards the brake structure when pilot pressure is applied in the brake chamber (92).

    一种制动阀(1)包括主体(10)、能够在主体(10)内移动的轴(20)、阀芯板(60)以及布置在主体(10)内的第一弹簧(40)和第二弹簧(50),其中,阀芯板(60)能够在释放结构与制动结构之间移动,其中,轴(20)适于与被配置为使轴(20)滑动的第一致动器(70)连接,制动阀(1)包括连接到制动腔室(92)的命令流体端口(90),与主体(10)和轴(20)一起限定制动腔室(92)的阀环(95),所述阀环(95)被配置为当先导压力施加在制动腔室(92)中时,将轴(20)移向致动位置或者推动第二弹簧(50)以将阀芯板(60)移向制动结构。
