1. A compressor module, comprising:
a compressor housing having a high-pressure chamber and an outlet for a compressed refrigerant and a separation apparatus being received in said high-pressure chamber for separating a lubricant being mixed with the refrigerant, said compressor housing further having a receiving member, said separation apparatus having a hollow-cylindrical separation portion and a funnel-shaped outlet portion protruding therein with an annular space being formed for the refrigerant, said compressor housing further having a plurality of form-locking contours and a housing wall, at least one of said form-locking contours is provided in said housing wall which adjoins said outlet and which protrudes into said high-pressure chamber;
a lubricant reservoir connected to said receiving member, said separation apparatus resting with a portion end of said hollow-cylindrical separation portion in said receiving member, and with said funnel-shaped outlet portion at least partially in said outlet; and
said separation apparatus being securely retained in said compressor housing by means of a form-locking connection so as to prevent torsion and/or axial displacement, said separation apparatus having in a region of said funnel-shaped outlet portion a plurality of form-locking elements which engage in corresponding ones of said form-locking contours formed in said compressor housing.
