Abstract

PURPOSE: To prevent dewing by a method wherein a by-path of small diameter is provided in an inlet passage and after closing the inlet passage, the air is sucked through the by-path to obtain a set pressure.
CONSTITUTION: An inlet passage 20 and a by-phth 21 with a smaller diameter than the inlet passage 20 are provided on suction side of a compressor body 2, and check valves 22 and 23 to prevent a fluid from being discharged outwardly from the compressor body 2 are provided on the passages 20, 21. The compressor body 2 is activated by a driving source 1, and when pressures in an oil reservoir 3 and an air tank 9 rise to a value somewhat near a set point on a pressure switch 17, the valve 23 is closed. Since the air is sucked through the by-path 21 of small diameter to compression even after the valve 23 is closed, an operating time of the compressor body 2 is extended and the compressed air temperature is maintained at a dew point temperature or over.
