System

The utility model relates to a system. In one embodiment, a system includes a source providing air; a first compressor stage receiving the air from the source and configured to compress the air to a first pressure; and a second compressor stage receiving the air from the first compressor stage and configured to compress the air to a second pressure. The system also includes a first component; a second member; a valve that controls the flow of the air; and a controller configured to control the valve according to a first control mode in which the air is supplied to the first component by the first compressor stage and a second control mode in which the air is supplied to the second component by the second compressor stage. 本实用新型涉及一种系统。一种系统包括：源，该源提供空气；第一压缩机级，该第一压缩机级从该源接收该空气并被配置为将该空气压缩到第一压力；以及第二压缩机级，该第二压缩机级从该第一压缩机级接收该空气并被配置为将该空气压缩到第二压力。该系统还包括：第一部件；第二部件；阀，该阀控制该空气的流动；以及控制器，该控制器被配置为根据第一控制模式和第二控制模式来控制该阀，在该第一控制模式中，该空气由该第一压缩机级供应到该第一部件，在该第二控制模式中，该空气由该第二压缩机级供应到该第二部件。
