- the invention relates to a compressor for refrigerants, comprising an outer casing, a arranged in the outer casing scroll compressor with a first, fixed in the outer housing compressor body and a second compressor body movable relative to the first compressor body, each one floor and above the respective floor have uplifting first and second spiral ribs, which interlock, that for compressing the refrigerant, the second compressor body opposite the first compressor body on an orbital track about a central axis is movable, a drive unit for the second compressor body with an eccentric drive, a drive shaft, a in a motor housing arranged and flowed around by the sucked refrigerant drive motor and a bearing unit for the drive shaft, which has a first, with the Enclosed outer housing comprises bearing body.
- the drive motor sits in an inner shell, which via a support element an outer casing is supported to the generation of noise and To suppress vibrations.
- the invention is therefore based on the object, a compressor of generic type to improve that of the scroll compressor sucked refrigerant is as much as possible free of lubricating oil.
- the gap could still be unilaterally the drive unit be arranged. It is particularly useful in terms of possible large available space when the gap the Surrounds drive unit and thus runs around the drive unit on all sides, for an optimal use of free space in the outer housing too receive.
- the gap is not only for the arrangement of the oil separator but preferably used in many ways.
- An appropriate solution looks like this in that in the space from the oil separator separated oil in Direction of the oil sump moves and refrigerant toward a suction chamber of the scroll compressor flows.
- the space in more diverse Way using arrangement allows a particularly compact design the compressor of the invention.
- the oil separator at least partially on an outside of the first bearing body is arranged, since in this area suitable Space is available.
- the oil separator can then arrange, if this at least partially surrounds the first bearing body.
- Another favorable arrangement in addition to or as an alternative to arranging the ⁇ labscheiders on the outside of the bearing body provides that the oil separator at least in sections on an outer side of the motor housing is arranged, since in this area much space is made available can, without significantly increasing the size of the compressor. It is particularly advantageous if the oil separator at least partially surrounds the motor housing.
