Beschreibung
Zusammenfassung:A parking brake device for motor vehicles includes at least one compressed air connection, an inlet venting-solenoid valve unit, a relay valve and at least one first compressed air outlet. The compressed air connection is connected to the inlet venting solenoid valve unit and the relay valve. A control line is provided such that the relay valve is connected or can be connected to the inlet venting solenoid valve unit, wherein the control line has a first branch and a second branch upstream of the relay valve. An output line is provided, which is connected to the at least one first compressed air outlet and has an output branch. A spring brake line is connected via the first branch to the control line and via the output branch to the output line, and a trailer valve line is connected via the second branch to the control line. The parking brake device has a spring brake valve, which is arranged in the spring brake line and is connected to the relay valve, and a throttle unit, which is situated in the spring brake line between the output branch of the output line and the first branch of the control line.
