For example it would be conceivable to design the connection unit so that the Adjustment part with an outside of the recording Element the connection between the suction gas connection and the Intake connection or the cooling duct connection.
  • a particularly favorable solution provides that the recording one Has interior, in which the cooling duct connection and Intake connection open and that in each of the positions of the Adjustment part either the cooling duct connection or the intake connection can be covered. This solution therefore has the advantage that it is very compact because the cooling duct connection is closed or the suction port through a in the Interior engaging area of the adjusting part takes place.
  • a particularly favorable solution provides that the interior the receptacle has an approximately cylindrical shape because in this case the corresponding setting part easy to manufacture.
  • a particularly advantageous solution provides that the Interior of the recording itself as a recess in a partition which extends the cooling duct and the intake duct separates from each other, because in this case the cooling duct connection and arrange the suction port so cheap let them flow into the interior.
  • a particularly useful in terms of compact design Solution provides that the adjustment part in the interior can be used and thus saves space in the inventive Refrigerant compressor is integrated.
  • the adjusting part absorbs a suction gas filter.
  • the setting part can be implemented as simply as desired, if this has a cover body with which either the cooling duct connection or the suction connection can be closed is, so that the suction gas supplied via the suction gas connection enters the connection that is not closed.
  • the cover body could be of any complexity.
  • a particularly advantageous solution provides that the cover body has an approximately semi-cylindrical shape, so that yourself with this in a simple manner the cooling duct connection or the suction port can be covered if this in a cylindrical wall of the interior open.
  • a flange plate is arranged on the adjusting part which is on a connection flange of the connection unit can be placed so that on the one hand with this plate Fixing of the setting part is done and then on the flange plate itself for the supply of the suction gas necessary elements could be connected.
  • the flange plate on one side of the adjustment part has a different shape than on an opposite one Page. This is already the most different Shape of the opposite one another Pages in a simple manner the position of the flange plate and thus the position of the adjustment part is recognizable.
  • An embodiment of a refrigerant compressor according to the invention 10 includes one designated as a whole by 12 Motor unit and a compressor unit designated as a whole by 14, both in a common compressor housing 16 are arranged.

  • the refrigerant is supplied via a suction gas pipe 28, which is led to a suction gas shut-off valve 30.
  • the Suction gas shut-off valve 30 is at 32 as a whole designated connector mounted, which over a Cooling channel connection 34 with a cooling channel 36 in connection is provided in section 18 of the compressor housing 16 is and serves to draw in refrigerant through a the engine compartment 38 accommodating the engine 20 and thus also through to pass the engine 20, the cooling channel 36 the drawn in refrigerant after flowing through the engine 20 a cooling channel outlet 40 leads.
  • an intake duct 46 can be supplied which is led to a compressor stage inlet 48.
  • the cooling duct outlet 40 preferably also opens into the suction channel 46, so that this also through the cooling channel 36 flowing refrigerant to the intake duct 46 and over this can be fed to the compressor stage inlet 48.
  • the compressor stage 26 the refrigerant is compressed, which then via a compressor stage outlet 50 is dissipatable.
  • Fig. 2 and 3 are the cooling channel 36 and the intake duct 46 through one in the compressor housing 16 provided wall 60 separately and following the wall 60 through an outer housing wall 62 and an in Distance from this inner housing wall 64 limited.
  • the wall 60 extends up to the connection unit 32 and is to form a receptacle 66 with a Provide recess so that the receptacle 66 an interior 68 can form, which is between the outer housing wall 62 and the inner housing wall 64 extends and in which the cooling duct connection 34 and the suction connection 44 open.
  • adjustment part In the interior 68 of the receptacle 66 there is a whole with 70 designated adjustment part can be used via an outer opening 71, which, as shown in Fig. 4 and 5, one with its outer surface to a cylinder axis 72 approximately has semi-cylindrical cover body 74, which in turn is firmly connected to a flange plate 76 is.
  • the approximately semi-cylindrical to the axis 72 Cover body 74 can be inserted into receptacle 66 that the cylinder axis 72 is transverse, preferably vertical to the outer housing wall 62 and inner housing wall 64 extends, with the cover body 74 in the direction of Cylinder axis 72 has a length so that it with his the bottom plate 78 facing away from the flange plate 76 in the Recording 66 inserted condition up to the inner housing wall 64 is sufficient, and preferably ends with this.
  • the cover body 74 encloses in the form of a cylinder jacket an inflow space 82 and further points because of it only approximately semi-cylindrical shape still has an opening 80, via which suction gas from that enclosed by the cover body 74 Inflow space 82 can emerge.
  • the flange plate 76 also has an inflow opening 84 on, which represents a suction gas connection, via which the Suction gas shut-off valve 30 in the direction of the cylinder axis 72 Suction gas can flow into the inflow space 82.
  • a suction gas filter 86 can be used, specifically in such a way that of the Sauggasabsperrventil 30 via the inflow opening 84 incoming suction gas first the suction gas filter 86 penetrates and then enters the inflow space 82.
  • the cover body 74 with the flange plate 76 is, as in FIG. 2 and 3 shown, can either be inserted into the receptacle, that the cover body 74, the cooling duct connection 34 essentially covers and thus prevents the suction gas from the Inflow space 82 enters the cooling channel 36, but the Opening 80 faces the suction port 44, so that the Suction gas from the inflow space 82 via the intake port 44 in the intake duct 46 can enter, as shown in FIG. 2 is.
  • cover body 74 in such a way that that this the cooling duct connection 34 or the suction connection 44 only partially covers, so that always a certain proportion of the suction gas enters it, but the larger proportion of the suction gas into the intake port 44 or the cooling channel port 34 occurs. It is also possible to have intermediate positions to provide the cover body 74, in which this partially the intake port 44 and the cooling channel port 34 covers, so that also in the intake port 44 and portions of the suction gas entering the cooling duct connection 34 are adjustable in intermediate stages.
