Problems solved by technology

Unintentionally high pressures can build up in the control line of the electrically controllable parking brake system in this way, which can lead to unintentional braking of the parking brake system
Furthermore, designed components, especially if they are contaminated or frozen, can lead to undesired formation of noise in the exhaust of the control line

Embodiment Construction

[0032] figure 1 A circuit diagram of an electrically controllable parking brake system is shown. The electrically controllable parking brake system 90 is connected via a non-return valve 10 to a compressed air treatment system (not shown). An optional filter unit 12 is arranged downstream of the non-return valve 10 , through which compressed air is fed to a supply solenoid valve 14 designed as a 2 / 2-way valve. The first working connection 20 of the control valve device 22 is connected to the outlet of the supply solenoid valve 14 via the first supply line section 16 and the optional throttle valve 18 . The line section with the filter unit 12 is indicated as the second supply line section 16'. The control valve device 22 is designed as a pneumatically controllable 2 / 2-way valve. The second working connection 24 of the control valve device 22 leads via a trailer control line branch 42 to the control inlet 26 of the trailer control module 30 . The trailer control module cont...
