ABSTRACT:
Disclosed herein is a fixed scroll of a scroll compressor capable of preventing gaseous refrigerant, that is heated in the compressor or contains a large amount of oil scatted in a compression unit, from being introduced into a compression chamber. The fixed scroll includes an open involuted wrap provided at a lower surface thereof, a compression chamber defined in the wrap, a plurality of mounting legs formed at a lower surface of a flange portion around the wrap, and an interceptive guiding portion configured to guide suctioned gaseous refrigerant, introduced to the lower surface of the flange portion, to a tip end of the wrap while preventing the gaseous refrigerant from being circulated between the mounting legs underneath the lower surface of the flange portion, thereby allowing the refrigerant to be introduced into the compression chamber.
