Abstract (en)

A scroll-type compressor having an improved seal structure includes a stationary scroll (11) and a movable scroll (21). Gas is discharged to an inner zone (44) through a discharge port (35) in accordance with orbital movement of the movable scroll (21). The seal structure includes a seal member (46), which is located between a movable base plate (23) and a radial projection (42). The seal member (46) substantially prevents gas that is discharged from the discharge port (35) from flowing radially from the zone (44). The seal member (46) is moved axially by the force of gas pressure. <IMAGE>
