<p><P>PROBLEM TO BE SOLVED: To reliably discharge oil in a secondary storage while suppressing the flow of compressed air into a compressor body when recovering the oil stored in the secondary storage of an oil separator. <P>SOLUTION: A refueling type compressor includes an oil separator 7 that includes a primary storage for storing oil subjected to primary separation, a filter 13 through which compressed gas after the primary separation passes and which causes the oil remaining in the compressed gas to be subjected to secondary separation, a secondary storage 13a for storing the oil separated by the filter, and a recovery pipe 14 for recovering the oil stored in the secondary storage on a compressor body side. The secondary storage is formed in a bottom member 22 for closing the bottom of the filter, the bottom member being provided with an opening 22b for causing the secondary storage to communicate with the primary storage and an opening/closing device 23 for opening/closing the opening. The opening/closing device operates to close the opening while the compressor is in operation, and opens the opening while the compressor is stopped so as to discharge the oil stored in the secondary storage to the primary storage. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
