Abstract: This scroll compressor includes a scroll compression unit including a first fixed scroll including a first fixed base plate and a first fixed spiral wrap, an orbiting scroll arrangement (7) including a first orbiting spiral wrap (14), the first fixed spiral wrap and the first orbiting spiral wrap (14) forming a plurality of first compression chambers. The scroll compressor further includes a refrigerant suction part suitable for supplying the scroll compression unit with refrigerant to be compressed. The orbiting scroll arrangement (7) further includes a first orbiting guiding portion (21) extending from an outer end portion of the first orbiting spiral wrap (14) and configured to guide, in use, at least a part of the refrigerant supplied to the scroll compression unit towards the first compression chambers.
