New low loss valves have been designed for an existing railroad air brake compressor. Prototypes of these valves have been built and tested in the laboratory. These valves increase the efficiency of the compressor by 13 % when operating at full load and rated speed with corresponding improvements at lower speed and when unloaded. Total operating hours on the test compressor with the high efficiency valves installed total over 4000 as of 1/1/86.
