PROBLEM TO BE SOLVED: To provide a structure of a discharge part of an aftercooler drain in a compressor for discharging a drain without freezing. SOLUTION: A drain is discharged from a drain discharge port 56 by merging a branched circuit 70 communicated with an outlet 22 of an aftercooler 20, a drain circuit 50 communicated with a drain collection unit 33, and a bypass circuit 60 communicated with a primary side of the aftercooler 20. The drain is adequately heated by merging hot compressed gas before passing through the aftercooler 20 in the drain, thereby the drain is prevented from being frozen. COPYRIGHT: (C)2004,JPO
