    Abstract: Provided is a scroll compressor. The scroll compressor may be provided with at least one refrigerant accommodating groove recessed to a preset depth in at least one from a side surface of a fixed wrap constituting a compression chamber and a side surface of an orbiting wrap. Thus, a volume of the compression chamber in a discharge area may be increased in correspondence with a volume of the at least one refrigerant accommodating groove, and a space into which liquid refrigerant, etc. may escape may be ensured to resolve excessive compression in the compression chamber. Then, a stress exerted on the fixed wrap is reduced, and a damage to the fixed wrap due to pressure in the compression chamber may be suppressed.

    Abstract: Scroll compressor including
    a casing (110);
    a driving motor (120) comprised inside the casing (110);
    an orbiting scroll (150);
    a fixed scroll (140) through which a suction port (1421) extends from an outer circumferential surface of the fixed scroll (140)
    a refrigerant suction pipe (115) penetrating through the casing (110) and inserted into an inlet end of the suction port (1421),
    whereby a reinforcing unit (145) is provided between an outlet end (1421b) of a suction port (1421) and an outer circumferential surface of the fixed wrap (144) facing the outlet end of the suction port. The reinforcing unit (145) overlaps a part of the outlet end (1421b) of the suction port (1421) in a radial direction when being projected in an axial direction.
