A pneumatic ABS valve arrangement (10) for a pneumatic brake system (8) of a vehicle, the pneumatic ABS valve arrangement (10) comprising: a housing (1) configured to be fluidly connected to a pneumatic brake, the housing (1) having a supply port (2) for receiving pressurized air; a working port (3) for providing brake pressure to the brake actuator (9); an exhaust port (4) for releasing pressurized air from the brake actuator (9); and a flow path (17) defined in the housing (1) and connecting the working port (3) and the exhaust port (4); the pneumatic ABS valve device (10) further comprises a quick release insert (5) reversibly deformable and arranged at least partially in the flow path (17), where the quick release insert (5) is movably received in the housing (1) and configured to move to a blocking position (B) when the working port (3) provides the exhaust gas flow (f2). According to the invention, the quick release insert (5) is configured to deform in a blocking position (B) in order to sealingly bear against a sealing surface (28) of the housing (1) in order to block the flow path (17), and the quick release insert (5) is graded to an undeformed base position (A) in an unloaded or low-loaded state.
一种用于车辆的气动制动系统(8)的气动ABS阀装置(10),气动ABS阀装置(10)包括:壳体(1),壳体(1)被构造成流体连接到气动制动器,壳体(1)具有用于接收加压空气的供应端口(2);工作端口(3),其用于向制动执行器(9)提供制动压力;排气端口(4),其用于从制动执行器(9)释放加压空气;以及流动路径(17),其限定在壳体(1)中并且连接工作端口(3)和排气端口(4);气动ABS阀装置(10)还包括:快速释放插件(5),其能够可逆地变形并且至少部分地布置在流动路径(17)中,其中快速释放插件(5)能够移动地接收在壳体(1)中且被构造成当工作端口(3)提供排气气流(f2)时移动到阻挡位置(B)。本发明建议快速释放插件构造成在阻挡位置(B)变形以密封地抵靠在壳体(1)的密封表面(28)上从而阻挡流动路径(17),且快速释放插件(5)在无负载或低负载状态下缓变到未变形的基本位置(A)。
