    摘要: A centrifugal gas compressor having a shrouded rotatable impeller 14 in an impeller chamber 40, and provided with capacity control vanes 30 and a diffuser passage 18 throttle plate 38, is provided with surge control means including a thermistor 50 which senses a temperature rise beyond a predetermined value in the impeller chamber and exterior of the gas flow path through the impeller, and through relay means such as 52, 58 electrically connected to the thermistor 50 operates to change the compressor operation to a nonsurging condition.
