摘要： The valve comprises a relay valve unit constituted by a main valve disc having an axial exhaust bore therethrough, and normally biased to a closed position, and a control piston assembly for adjustably moving the main valve disc to the open position, and a modulated-pressure control valve unit operable to supply a pressure, modulated in accordance with the loading of the vehicle, to the control piston assembly. The control piston assembly includes first, second and third pressure-responsive pistons with the first piston being cooperable with the main valve disc and the third piston being interengageable with the first and second pistons. A loading spring is engaged with the second piston, an indicated pressure chamber is formed between the first and second pistons, and a modulated-pressure chamber is formed beneath the third piston and is in communication with the control valve unit. A stroke adjuster, operable in accordance with the loading of the vehicle, is operatively associated with the control valve unit, and the control valve unit includes a spring biased check valve opened, when the modulated pressure exceeds the supply pressure, to equalize the modulated pressure and the supply pressure.
