Abstract
An air compression device includes a rotary compressor, a discharge flow channel, a release flow channel and an operation control unit. The discharge flow channel is connected to a discharge portion of the rotary compressor. The release flow channel is disposed to be connectable to the discharge flow channel. The operation control unit is configured to perform a release operation of releasing a part or all of compressed air remaining in the discharge flow channel through the release flow channel when the operation control unit controls to stop the rotary compressor.
