Claim 18:
19. The scroll compressor of claim 1, further comprising a suction guide that is connected to a non-orbiting scroll defining the compression part between the high and low pressure separation plate and the non-orbiting scroll, the suction guide being configured to guide refrigerant suctioned into the low-pressure part to be suctioned into the compression chamber,
wherein the suction guide comprises:
a suction guide protrusion extending from an outer circumferential surface of the non-orbiting scroll toward the inner circumferential surface of the casing, and
a suction guide passage formed through an inside of the suction guide protrusion, the low-pressure part and the compression chamber being in fluid communication with each other, and
wherein the suction guide protrusion has (i) an outer wall surface radially facing the inner circumferential surface of the casing or the inner circumferential surface of the high and low pressure separation plate, (ii) side wall surfaces extending from both sides of the outer wall surface in a circumferential direction, (iii) an upper wall surface connecting the outer wall surface and the side wall surfaces and facing an axial inner surface of the high and low pressure separation plate, and (iv) a lower wall surface facing the refrigerant suction pipe and an inner wall surface facing the compression chamber,
wherein the outer wall surface, the side wall surfaces, and the upper wall surface are closed, and
wherein the lower wall surface is open.
