PROBLEM TO BE SOLVED: To provide a compressor restricting energy loss due to unnecessary load added to a compressor body and a drive source. SOLUTION: The compressor includes, in the path of an unloader pipe 15, a second tank 21 to store compression gas to be sent to an unloader cylinder, an opening/closing valve 22 provided between the second tank 21 and a first tank 17 allowing the compression gas flow to the second tank 21, and an electromagnetic selector valve 23 provided between the second tank 21 and unloader cylinder switching between a state for introducing compression gas in the second tank 21 to the unloader cylinder and the state for discharging compression gas in the unloader cylinder.
