Abstract
In a scroll type compressor, a discharging port in a side plate of a stationary scroll member is formed in an elongated shape, such as an oval, so that a tip-seal element provided in the beginning area of a movable spiral body does not interfere with the discharging port in the course of an orbital motion, whereby damage to the tip-seal element due to a draw-in thereof to the discharging port can be avoided, while ensuring a sufficient fluid pressure and full sealability.
