The invention discloses a brake valve buffer cavity pressure regulating mechanism and a brake valve assembly, and the brake valve buffer cavity pressure regulating mechanism comprises a shell which is provided with an inner cavity, and an air inlet channel and an air outlet channel which are communicated with the inner cavity; the air valve moves in the inner cavity, when the air valve is at a first position, the air valve closes the air inlet channel and the air outlet channel, and when the air valve is at a second position, the air valve conducts the air inlet channel and the air outlet channel; the opening mechanism comprises a pushing piece used for abutting against the air valve to push the air valve to move and a pressure relief channel arranged on the pushing piece, the pressure relief channel is communicated with the outside, and the pushing piece moves in the inner cavity and is provided with a closing position for closing the pressure relief channel and a pressure relief position for communicating the pressure relief channel with the air outlet channel; an expansion cavity and a control channel communicated with the expansion cavity and the outside are further formed in the shell, and when the air pressure in the expansion cavity is increased, the expansion cavity expands and stretches to drive the pushing piece to move towards the pressure relief position. Adjustment of air pressure in the buffer cavity can be conveniently controlled.

    本发明公开了制动阀缓冲腔调压机构及制动阀组件,其中制动阀缓冲腔调压机构包括:壳体,具有内腔、与内腔连通的进气通道和出气通道;气门阀,活动在内腔中,在第一位置时,气门阀关闭进气通道和出气通道的导通,在第二位置时,气门阀导通进气通道和出气通道;开启机构,包括用于与气门阀相抵接以推动气门阀活动的推动件和设置在推动件上的泄压通道,泄压通道与外界连通,推动件活动在内腔中并具有封闭泄压通道的封闭位置和连通泄压通道与出气通道的泄压位置;壳体内上还具有膨胀腔和连通膨胀腔与外界的控制通道,当膨胀腔内的气压增大时,膨胀腔膨胀伸展以带动推动件朝泄压位置移动。本发明能够方便的控制缓冲腔内的气压的调节。
