An electropneumatic brake control module () has a supply connection () for connecting a compressed air supply (); a first wheel brake connection () and a second wheel brake connection (); a pneumatically controlled inlet-outlet valve unit () for controlling a first brake pressure (PB) at the first wheel brake connection () and a second brake pressure (PB) at the second wheel brake connection (), which is independent of the first brake pressure (PB); and an electropneumatic pilot control unit () for controlling at least one main control pressure (PH) at a main valve () of the inlet-outlet valve unit (). The main valve () of the inlet-outlet valve unit () is a pneumatically controllable 3/2-way valve () with a main valve control connection ().

Electropneumatic axle modulator with directly controlled valves

A valve apparatusfor a pressure-actuated system has a pressure medium inputand a pressure medium output. A relay valvecontrols the pressure medium input. A pressure-actuatable inlet valveis arranged between the relay valveand the pressure medium output. Each pressure medium outputincludes a pressure-actuatable outlet valvecontrolling a fluidic connection of the pressure medium outputto a purgeleading to atmosphere. At least one outlet valveor inlet valveis formed as a diaphragm valve and has a valve diaphragmwhich lies on a valve seatand opens against the pressure in a purge chamber. For each diaphragm valve, an electrically actuatable purge valvecontrols a fluidic connection of the purge chamberto a purge line controlling the relay valve
