The invention discloses a pressure regulating type relay valve. A relay piston is divided into three sections; a first pressure regulating cavity and a control cavity are formed; a pressure regulatingstructure is arranged between the first pressure regulating cavity and the control cavity; when a brake pedal is stepped down, the air pressure of the brake main valve enters through a control inletto push the relay piston to move; through pressure change of gas entering the control cavity and the first pressure regulating cavity by the pressure regulating structure, output of pressure in the control cavity is realized, and output of different brake pressures by a brake air chamber is realized, so that the functions of gently treading and heavily treading and heavily braking are realized, and the problem of fatigue and weakness of brakes of large heavy trucks and other vehicles in the domestic market is solved.

    本发明公开了一种调压式继动阀,将继动活塞分为三段,且形成第一调压腔和控制腔,在所述第一调压腔和所述控制腔之间设置有调压结构,在踩下刹车踏板时,制动总阀气压经过控制入口进入推动继动活塞移动,通过调压结构对进入所述控制腔和所述第一调压腔的气体的压力变化,来实现所述控制腔内的压力的输出实现制动气室输出不同的制动压力,来实现轻踩轻刹、重踩重刹的功能,解决国内市场车辆大型重卡车等刹车疲软的问题。
