An air inlet (13) and an air outlet (14) are arranged on the valve body(]). An ejector rod (2), -7a/valve seat (3) and a sandwich valve (4) are arranged in the valve body (I). A lower portion of the ejector rod (2) is located in the / \ ,. valve seat (3), and an upper portion oftheejctor rod (2)iscon nected to an ejector rod driving mechanism. An ejector rod spring t1(5) is sheathed on the ejector rod (2). Thesandwich valve (4) is provided at a valve parl (6) of the valve seat (3).Asandwich valve 3 /spring (7) is provided under the sandwich valve (4). In a lbst re lief position, the sandwich valve (4) communicates a chamber A (8) with a chamber 13 (11) in a small-flux mode, By providing - the reliefregtlating valve a a relief passage of a vehicle brake system, thecalibre of the relief passage of the brake system can /he changed by means of the operation of the ejector rod driving mechanism, such that the vehicle brake system has different re lief timie periods, the vehicle has the function of having di fferent G relieftime periods wider diftrent working conditions, aid thus \ 4corresponig requirements for the vehicle brake system are met. -_ W O 2018/018744 A l 111111111111111111111111111liiil l i1111|0 HI||| il||101|I111111111111111111111111 11ii (84) jil -(, IMOl ij I412012 h f'c ): ARIPO (BW, GilGM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), IkR (AM, AZ, BY, KG, KZ, RU, TJ, TM), Kk (AL, AT, BE, BG, CI, CY, CZ, DE, DK, EL, ES, FL, FR, GB, GR, IIR, 1U, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, Ci, CM,GA,GN,(GQ,GW,KM,ML,MR,NE,SN,TD,TG) - M ~Lf#£(+ J421&(3)).
