- the supply of lubricant to the Axialstschreib is favored from an outer side thereof ago.
- the lubricant supply between the Axialstschreib design and the slider can also be further favored by the fact that the Axialstschreib construction and / or the Axialstschreib construction bearing Gleitstschreib products with microwells, for example, material-related and / or incorporated and / or embossed well structures are provided which receive lubricant available hold and distribute.

- Such pockets with the cylindrical receptacles facing openings have the advantage that it is entrained by these lubricants in the orbiting movement of the second compressor body base and thus lubricant can always be transported to the cylindrical receptacles.
- the effect of the pockets is particularly favorable if the openings of the pockets are each overlappingly positionable with two cylindrical receptacles arranged successively in the direction of rotation, that is to say that in this case the openings of the pockets have an angular extent such that they are in the orbiting movement of the pockets Compressor body base in each rotational position in each case two pockets can connect to each other and thus can advantageously transport lubricant from a cylindrical receptacle to the other cylindrical receptacle.

- the pockets 204 are arranged to extend around either side of a geometric arc 208 about the central axis 46, which intersects the holes 202 in the center to always achieve optimum overlap with the receptacles 194.
- the concept of the lubrication of the axial guide 96 and the coupling element sets 162 is particularly advantageous when the central axes 44 and 46 of the compressor body 24 and 26 are normally lying, that is at a maximum angle of 30 ° to a horizontal, extending in the Compressor housing 12, in particular in the region of the first housing body 72 at a lowermost position in the gravitational direction forms a lubricant bath 210 from which swirled lubricant in the operation and is received and distributed in the manner described.
- the drive of the movable compressor body 24 is effected by a drive motor designated as a whole by 212, which in particular has a stator 214 held in the central housing body 84 and a rotor 216 arranged inside the stator 214, which is arranged on a drive shaft 218 which is coaxial with the central axis 44 of the stationary compressor body 24 extends.
- the drive shaft 218 is mounted on the one hand in a bearing unit 222 arranged between the drive motor 212 and the spiral compressor unit 22 and in the central housing body 84 and on the other hand in a bearing unit 224 which is arranged on a side of the drive motor 212 opposite the bearing unit 222.
- the bearing unit 224 is mounted, for example, in the second housing body 86, which closes the central housing body 84 on a side opposite the first housing body 72 side.
- aspirated medium in particular the refrigerant
- the drive shaft 218 drives the movable compressor body 26 via an eccentric drive designated as a whole by 232, which moves in an orbiting manner around the central axis 44 of the stationary compressor body 24.
- the eccentric drive 232 in particular comprises an eccentric pin 234 held in the drive shaft 218, which moves a driver 236 on an orbital path about the central axis 44, which is rotatably mounted on the eccentric pin 234 and in turn is rotatably mounted in a rotary bearing 238, wherein the pivot bearing 238 a Turning the driver 236 relative to the movable compressor body 26 allowed.
- the follower 236 is limitedly rotatable relative to the eccentric pin 234 and relative to the cam receiver 242 and allows for adjustment of the radius of orbital movement of the movable compressor body 26 to hold the spiral ribs 34 and 38 in abutment with each other.
- the second compressor body 26 is provided with a driver receptacle 242 which receives the pivot bearing 238.
- the cam receiver 242 is set back relative to the flat side 98 of the compressor body base 36 and thus integrated in the compressor body base 36, so that the forces acting on the movable compressor body 26 driving forces on one of the spiral rib 38 side facing the Flat side 98 of the compressor body base 36 are effective and thus drive with low tilting moment the movable compressor body 26, as viewed axially through the axial guide 96 in the direction of the central axis 44 between the driver receptacle 242 and the electric motor 212 on the Axialstütz construction 102 and guided transversely to the central axis 44 movable is.
