Abstract (en)

The present invention is intended to provide an oilless scroll-type compressor which can obtain a high compression efficiency with highly accurate sealability retained and particularly has such a constitution that a chip seal (9b) fitted in each of the wrap end surfaces of stationary scrolls and an orbiting scroll is integrated with a backup seal, a discharge port (7) in communication with a wrap groove terminal end through a through-hole (31) is formed in a land section (4) positioned on the interior side of a wrap inner circumferential end on the side of one scroll and situated around a shaft hole (6) through which a main shaft is inserted, and the circumference of said discharge port (7) is surrounded by the chip seal (9a) extended from said wrap. <IMAGE>
