The invention discloses a brake valve, a brake system and an automobile. The brake valve comprises a valve body, a first piston, a second piston, an air valve and a shielding part. The first piston slides along the inner side wall of the upper cavity, and the size of the first piston is not consistent with the size of the second piston. The valve body is provided with a first air inlet hole communicating with the upper driving cavity, an air inlet hole supporting column extending in the moving direction of the first piston and a second air inlet hole formed in the air inlet hole supporting column and communicating with the lower driving cavity, and the second air inlet hole extends in the extending direction of the air inlet hole supporting column. A supporting column penetrating hole matched with the air inlet supporting column is formed in the first body. The air inlet direction of the air inlet holes entering the driving cavity is set to be consistent with the moving direction of the piston, and the air hole supporting column penetrating through the upper portion is arranged on the valve body, so that the influence on the driving cavity located on the upper portion is avoided, and the arrangement design of the air inlet holes is more conveniently achieved.

    本发明公开了一种制动阀、制动系统及汽车,其中制动阀包括阀体、第一活塞、第二活塞、气门阀和遮挡部;第一活塞沿上腔室的内侧壁滑动,第一活塞的尺寸与第二活塞的尺寸不一致。阀体上设置有与上驱动腔连通的第一进气孔、沿第一活塞的活动方向延伸设置的进气孔支撑柱和设置在进气孔支撑柱上并与下驱动腔连通的第二进气孔,且第二进气孔沿进气孔支撑柱的延伸方向延伸设置;第一本体上形成有与进气孔支撑柱相适配的支撑柱穿孔。本发明通过将进入到驱动腔内的进气孔的进气方向设置呈与活塞的移动方向相一致,并且通过在阀体上设置穿设位于上部的气孔支撑柱避免对位于上部的驱动腔的影响,更方便的实现了进气孔的排布设计。
