<p>The testing unit is intended for adjusting and testing a pneumatically or hydraulically operated valve, which automatically controls the brake force of a vehicle, as a function of its load, or for vehicle brake testing. It comprises a panel (20) with an inlet connection (3) for an external pressure source, and at least three pilot pressure outlet connections (2,4,5). These connections are coupled to the inlet (3) via lines (21), each containing a pressure regulating valve (22) and a stop valve (23). Pressure gauges (24) are connected to the lines, and there may be at least two inlet connections (7,8) for brake cylinder pressure, which are connectable to the pressure gauges by change-over valves (27).</p> |
