Abstract
An axle valve module of a compressed air brake system includes a relay valve with a control pressure input connected to a control pressure line which can be connected via a changeover valve alternately to a brake pressure line conducting an introduced brake pressure or to a reservoir pressure line conducting a reservoir pressure. ABS inlet and outlet valves are each formed as a pressure-controlled diaphragm valve with assigned pilot valve, wherein the pilot valves are configured as cyclically controllable 3/2-way magnetic switching valves, A shut-off valve is arranged in the control pressure line of the relay valve, between the changeover valve and the control pressure input of the relay valve or the branch point of a control pressure line of the ABS valves, via which shut-off valve the control pressure present at the control pressure input of the relay valve can be locked in as required.
