The role of the distribution valve:
Into the main control of the compressed air, the main valve underground passage into the main piston above the space, pushing the piston down, compressed air brake spring, until the piston outside the bottom of the body, then the main valve in the inflatable relief position, Deputy air cylinder, pressure air cylinder, auxiliary room inflatable.
(1) auxiliary air cylinder inflatable: brake tube compressed air → a1 → a2 → deputy air cylinder inflatable check valve → b1 → b → deputy air cylinder. On the other hand by the deputy air cylinder inflatable check valve from b1 into the main valve balance valve cavity b2.
(2) pressure air cylinder inflatable: the main piston above the compressed air → a5 → inflatable stem groove a6 → conversion cover slot a7 → a8 → cut off → under the valve body a9 → Bureau of the valve under the main piston c1 → Upper valve body passage c2 → intermediate passage c3 → pressure air cylinder.
(3) auxiliary chamber inflatable: As the brake tube compressed air through a'1 into the auxiliary valve body a'2 (at the same time into the air valve a'3), to promote the auxiliary valve piston up, the auxiliary valve in the inflatable relief position. Brake tube compressed air c4 → auxiliary valve undercuts c5 → auxiliary valve sleeve → auxiliary valve → auxiliary valve above the f1 → f2 → f3 → auxiliary room.
(4) brake cylinder to ease: the main control in the relief position, the main piston to ease the pillar to move down to open the relief valve. Brake cylinder compressed air → d → d1 → d2 → d3 → d4 → relief valve exhaust port arrow → atmosphere. At the same time the main valve on the top of the piston d5 compressed air is also limited by the bottom of the valve to tighten the closure → pressure valve sleeve → pressure valve groove → d6 → d2 → d3 → d4 → ease the valve exhaust port → atmosphere.
(5) Bureau of the chamber exhaust: brake cylinder pressure to 20kPa below, the inflatable valve piston under the action of the spring force to open the inflatable valve stem tail air, the bureau pressure chamber air e → e1 → e3 → atmosphere
