Pneumatic Electric Braking Systems (EBS) are frequently used in commercial vehicles.
These systems are controlled at about 100 Hz, thus the dynamic behaviour of them is
essential to know. Since solenoid valves are playing important role in control, the
knowledge on the dynamic behaviour of these valves is essential. This paper presents
the development of a computer-controlled experimental facility, for investigation
of the Cq flow coefficient. This documentation presents the comparison of the experimental
methods to international literature and numerical flow simulations.
