Abstract
An automatic single-car test device for a distributor valve of a railway vehicle includes an air supply source, an adapter having a working chamber fitting, a valve chamber fitting, a reservoir fitting, a brake cylinder fitting, and a brake pipe fitting, an operating portion in fluid communication with the air supply source and the adapter, where the operating portion is configured to measure pressure within the working chamber fitting, the valve chamber fitting, the reservoir fitting, the brake cylinder fitting, and the brake pipe fitting and generate an electrical signal representing the respective pressure with the fittings. The test device further including a processing portion having a microprocessor, an input/output device, and a power supply. The processing portion configured to manipulate pressure within the working chamber passage, the valve chamber passage, the reservoir passage, the brake cylinder passage, and the brake pipe passage of the distributor valve via the adapter.
