Title: COMPRESSED-AIR SYSTEM FOR USE IN A RAIL VEHICLE
Abstract:
The invention relates to a compressed-air system for use in a rail vehicle, which comprises a compressor for producing compressed air in the compressed-air system, at least two compressed-air accumulators, a pneumatic engine starter for starting a diesel engine, and a compressed-air line system. The at least two compressed-air accumulators have a main compressed-air vessel and a starter compressed-air vessel, wherein the compressed-air line system connects the compressor, the at least two compressed-air accumulators and the pneumatic engine starter to each other in such a way that compressed air produced by the compressor is stored in the main compressed-air vessel and that compressed air can be conducted from the starter compressed-air vessel to the pneumatic engine starter. According to the invention, the main compressed-air vessel and the starter compressed-air vessel are connected to each other by means of the compressed-air line system and by means of a controllable valve in such a way that compressed air can be exchanged between the main compressed-air vessel and the starter compressed-air vessel, wherein the valve can be controlled in such a way that the compressed air can be conducted selectively from the main compressed-air vessel into the starter compressed-air vessel or from the starter compressed-air vessel into the main compressed-air vessel.
