Pressure regulator module for a motor vehicle pneumatic braking system

A pressure regulator module for a vehicle pneumatic braking system for a wheel-slip-dependent controlling or regulating of braking pressures applied to two separate working connections, the pressure regulator module comprising:

• a two-way valve assembly including one relay valve, respectively, for each conduit, each relay valve having a control input;
• wherein, a respective solenoid control valve in the form of a 3/2-way valve having two switching positions is assigned to the control input of each relay valve without inserting additional valves;
• wherein the solenoid control valves, together with only one additional solenoid control valve coupled on an input side of the module, connect the control input of the respective relay valve with at least one of a bleeding system, a control pressure, and a compressed-air reservoir.

A pressure regulator module for a pneumatic braking system of a utility motor vehicle, the pressure regulator module comprising:

• a two-way valve assembly having two conduits, a first conduit including a first relay valve and only one pressure regulating valve in the form of a 3/2-way valve, which 3/2-way valve is assigned to a control input of the first relay valve, and a second conduit including a second relay valve and only one second pressure regulating valve in the form of a 3/2-way valve assigned to a control input of the second relay valve;
• and
• wherein the first and second pressure regulating valves, together with only one additional pressure regulating valve coupled with an input side of the first and second pressure regulating valves, connect a control input of the respective first and second relay valves with a bleeding system, a control pressure, or a compressed-air reservoir.
